    24mm PC-E Episode 2

    OK so I got a replacement and had a chance to do a quick run of shots today: I wanted to ensure that it was at least satisfactorily sharp from edge to edge at f5.6 before I got into seeing how it is when shifted. Unlike my first copy, it is indeed acceptably sharp all over. In fact I think pretty darned good. You have to focus it VERY carefully: I think there's some field curvature so you have to make sure that the centre and edge are both in focus in LV within the available DOF (or you have to get lucky!) but get all that right and the signs are pretty promising. Interestingly, though there are mild signs of diffraction when stopping down to F8 or even F11, they are pretty insignificant and you do get a lot more DOF to play with and a touch more corner sharpness at F8.

    Many people, including me, have reported problems with this lens on the D800/E but I had heard a couple of people saying it was great. So far, shift tests pending, I am really pleased that I tried another one.

    Hi Tim,

    Of course I"m expressing the obvious when I say the real test is how it performs when lens is shifted to various degrees. Still it's a promissing start and one would like to first observe that unshifted, it appears to be a good sample. Looking forward to you additional tests.

    having never owned a tech cam... I'd be pretty happy with that as a starting place!

    Re: 24mm PC-E Episode 2

    OK guys ('n gals)

    More tests. I shot with shifts up and down (not showing the downs, they're irrelevant because of DOF and foreground) at up five and ten, and left and right five and ten. I also did my 'parallel floor' test where I tilt the camera down on the cube as far as it goes without the extension, then tilt the lens movement down a little, and use LV to focus in an attempt at getting the whole of the ground from very near to far in perfect focus.

    It was a doddle and worked well at both F8 and F11 and I suspect would have been great at wider apertures too.

    The shots are all linked here. The shifts were all done at F11 and please start at the second frame, since the first frame was shot yesterday and focussed differently. The shots are in 80% JPEG quality and are at 50% size so as to emulate a 200DPI print and so as to save on huge upload times!

    My conclusions: this is a good copy. I would happily use it for five and seven rise and for ten rise if the top of the frame was sky, or only had substantive subject in the centre 2/3rds of the frame. I would also happily use it for shifts of seven left and right; at ten shifts, it shows vignetting and the sharpness isn't great. Could it be better? Yes. Do I still hope to eventually see new PC lenses in Nikon mount that are wider, more flexible in terms of combinations of movements, and optically even better? Yes. But I also want world peace....

    uploading now...

    Tim, from your detailed descriptions, this copy sounds promising. I realize the reasons for not posting at 100%, which is where I would personally (and sure you have) evaluated a lens like this.

    I'm not sure with regards to the Current Nikon 24mm PC-E lens, if there is a better performing copy when a near-full shift is attempted, regardless of f-stop. I question if even used on a D700 and defraction limits occured at a smaller f-stop that on the D800 would it result in much of an increase of sharpness at the sides?

    Thanks Tim, it looks a lot better than your previous copy and give me heart for possibilities in building my own kit, where a 24mm and 45mm PC-E would be my prime go to lenses.

    And it's also fun: even as a walk around you can get some great effects and can do so without live view with a bit of practice. In this shot I was trying to nail a narrow band of perfect focus running right down the tunnel and I sort of got it!

    Re: 24mm PC-E Episode 2

    Absolutely lovely image. Your success in finding a good copy inspires me to look again at this lens. In shifting at f/5.6 and f/8 are the corners and edges becoming sleazy? Is f/11 required for optimally balancing sharpness over the full frame? I assumed so but would rather hear it from you. Thanks for these.

    Tim,

    You've given me hope -- I found a used 24PC the owner claimed was a very good copy, had him send me some pics and it looks as though I have a better than average copy arriving as well. If it works as well as I hope, the D800 becomes a *LOT* more versatile for me and MF+tech becomes less attractive to schlep...

    Thanks!

    I think the key thing is that this lens is very sharp indeed on centre, but that you really do need to stop down for sharpest edges and corners when shifting. I need a lot more shots under my belt to get the extreme specifics but I suspect that the need to stop down is at least in part a DOF issue: basic trigonometry shows that if you are bang in front of a building and have your sensor exactly parallel to it, then the top part of a shifted frame is a lot further away from the nodal point than is the part of the building directly in front of you. So I am next going to experiment with re-focussing between shifts, which I did not do in the series I posted.

    In any event, the resolution of the lens is good enough to withstand a stop down to F11. Sure you lose a bit, it starts to undersample the sensor, but it's still pretty good, and... it IS the only game in town!

    I hope yours is a good 'un!

    It is SO easy to accidentally leave one of the movements not exactly neutralised and then think you have a sh1t copy...

    I am headed the same way as you: this lens on this camera will not match MF but with careful technique and a good copy, it might just be close enough often enough to make some changes... possibly just to what I take where and when, and possibly even to what I own...

    Re: 24mm PC-E Episode 2

    I've had the Hartblei on both the Contax 645 w/ P25 back and the newer digital version on the Pentax 645D. I've owned the 24 PC-E and use it on both on the D3x and the D3s, I can tell you the MF versions of shift lenses are markedly inferior. Until Stefan starts making T/S lenses from Zeiss glass for medium format, the Nikon 24MM PC-E is the only game in town. The 24MM PC-E coupled with the D3x or D800 is an unbeatable combination - until Leica introduces the 30MM Elmar shift for the S2. Given their production record, that should be by 2029.

    I am so with you on that: I had the first S2 in the UK and even then, they were blandishing the TS lens as something on the near rather than far horizon!

    Re: 24mm PC-E Episode 2

    One thing I've been curious about is how a moderately shifted 24 PC-E would compare to the 14-24 zoomed out to encompass the same top-to-bottom/left-to-right area when cropped. Where it gets intriguing is when distortion correction is applied to both, especially since the 14-24 begins to noticeably distort afer 24mm and the 24 PC-E doesn't produce rectilinear results, at least by architectural standards, so lens correction is a foregone conclusion for each. Landscape use is a secondary concern for some. Existing resolution tests reveal the 14-24 is sharper towards the shorter focal length so I expect this could potentially be a bit of an eye opener.

    Tim, this was precisely what I was going to ask you when I made my first post on this thread earlier this morning. Then I deleted and rewrote my post and had forgotten to restate my question.

    I recall an earlier (fast and dirty) try of mine where I shifted approx 3 degrees and then refocused and compared to the the version that was not refocused. I repeated this with varying degrees of shift. From what I recall, depending if subject was flat field and in a single plane or not, it did make a surprising difference...but at the same time (depending on aperture), it also resulted in other moderately sharp parts of the image to go soft. Subject dependent and often times there will be some tradeoffs.

    I too was thinking about this when I had the 14-24...as to whether one could shoot wider than the 24 shift lens and then adjust for distortion and crop. I didn't have the 24mm PC lens at the time, so I couldn't do a direct comparison....but the 14-24mm is generally sharper on the wider end as you stated.

    Re: 24mm PC-E Episode 2

    And in the case of the rented 24PC-E I had, the 14-24 was already notably sharper at 24mm so... ??

    I played with a friend's 14-24 last week -- the center was great, but the corners were not much better on it than my 20 AF-D. I need to see this better 24PC on my D800, but my guess is it's eons better that squeezing and stretching pixels in post.

    I would agree, but I would also expect it to be somewhat dependent on the particular lens sample one tested for each and separately what camera this comparison was tried on...say a D3/D700 vs. D800? The 14-24mm corners on a D700 (especially at 24mm) when shot at f2.8 are somewhat soft but even f4 is quite acceptable and beyond, very good. This isn't quite the case when that lens is used with a D800. So the 14-24 may be an acceptable substitute for the 14mm f2.8 PC-E on a D700....but possibly somewhat more questionable if a D800 is used.

    Re: 24mm PC-E Episode 2

    Rather than doing any perspective edits (in all cases, starting with a level and plumb camera) I'm thinking simply comparing a vertical camera and subject with the 14-24 zoomed out as much as necessary to cover what the 24 PC-E sees and cropping. I'm guessing that as one zooms out the 14-24 to cover the equivalent angle of view of the shifted 24 PC-E that the barrel distortion will be very approximately equal with both lenses requiring a measure of lens correction for a truly rectilinear result. From what I've seen this doesn't seem too far fetched a notion.

    Tim,

    Your experience has given me renewed interest in the 24mm PC-E. I once owned this lens but sold it in one of my annual "purges" to lighten my bag. Now with the D800, I've been taking a new look at the lens, hoping that it had the potential to give me a T/S alternative to lugging the MF tech cam. The problem I'll be facing is how to get a good copy, relying on online retailers like B&H and Adorama. My local camera stores don't stock many lenses and rarely have anything this "eccentric".

    Cheers,

    Joe

    The story started here and ended via one dodgy lens, a centrefold problem with the sensor, and a decision to stick with Phase and upgrade to a 65+

    I'm a congenital early adopter, but that was my biggest mistake. The only reasons to be in that system were the glass and the ergonomics. The glass was very slow to be delivered and though the ergonomics were much nicer than a Phamiya body, the teething problems annoyed me and it was just too big to be a walkaround system. And if you're not walking, you might as well take the best tool for the job, i.e. the 65+. (at that time).

    Finally, I fairly quickly realised that the TS lens was essentially vapourware.

    Re: 24mm PC-E Episode 2

    I am curious as to why anyone would compare the 14-24 to the 24MM PC-E. You couldn't have two lenses whose purpose by design is more opposite each other, one a zoom AF and the other a manual lens designed for precise use exclusively on a tripod. While I have used the 14-24 for architecture it was only because the 24 was not wide enough and I was in a situation to where the shift wasn't a factor as in this image I shot (in 9 layers) of the lobby of the Comcast HQ in Philadelphia. The shot did require distortion correction of course, but the end result was fine.

    Re: 24mm PC-E Episode 2

    Thanks, Tim.
    Maybe you have said somewhere before, but what is your subjective opinion on base ISO IQ between the two cameras? I know this seems a bit (far?) OT, especially in a thread regarding a 24mm PC-E lens, but I'm interested in how the two camera bodies compare if used on tripod, in natural light and in a considered and deliberate manner as you would with such a specialist lens.
    If you'd prefer not to water down this thread with a reply, feel free to PM me if you have time.
    Thanks,
    T

    Aboud, I personally couldn't agree with you more in that both lenses are designed for very different purposes and use....not even close. The only reason I mentioned the possibility of using the zoom at a wider setting and then correcting distortion in post processing, is simply that samples of the 24PC I tried, were often subpar when shifted.....and in terms od edge to edge sharpness, the 14-24 was often superior. Short of switching systems, it was just a possible stop gap measure until Nikon possibly addressed the uniformity in sample to sample performance in the 24 PC.

    Well Dave, this lens has been available for a long time. It is obvious that Nikon's standards for consistency are wanting, even for a lens that costs about $2,000 a pop. Do I think they will raise their standards? If they haven't by now, I don't expect so.

    If you'd prefer not to water down this thread with a reply, feel free to PM me if you have time.

    Happy to answer Buddy... at base ISO (and I have never shot them both at the same time so this is memory against the present) there's effectively bugger all difference other than the fact that the D800 shadows push better and the Leica has better glass. Some prefer the colours of one versus the other. That's it!

    You make a very valid point Aboud. What I find interesting and a bit perplexing is some Nikon lenses have exceptional sample to sample constancy while others are fair at best. Generally wide angle zooms are the most difficult, since they deal with many small elements and groupings that are hard to align properly, whereas single focal length telephoto"s are generally the easiest, relatively speaking. One lens that also seems to have a lot of variability is the 24-70 f2.8 zoom. The Nikon 24PC I presume is a special case since achieving on axis performance may be relatively straight forward to achieve good performance, but requires considerable more effort and optical know-how to keep optical standards high when shifted. What exactly is the production issue is with some Nikon 24 PC samples, I simply don't know.

    Re: 24mm PC-E Episode 2

    Nikon turned the heat up on themselves by introducing this 36 megapixel body. That ought to cause some stir at the meetings around lens QC. Knowing there's likely even denser sensors on the way must have some influence in their future plans for lens resolution goals and manufacturing tolerances.

    Update: how to focus this lens

    This is really complicated. Really.

    Talking about shifts, rise in particular and in landscape orientation:

    I have shots where the top is in very good focus at 10 rise and F8. And this is on a planar subject (a building in front of me to which I am well aligned). Repeat: there is NO significant edge weakness even at extremes of shift. However, to get those sharp tops you have to focus in the middle of the top third of the frame in LV, and then the bottom third of the frame looks soft. If you focus in the centre of the frame you get an acceptable level of sharpness throughout, judges at 50% on scree, though the top is less sharp than before.

    At five rise, focus in the same way, maybe a touch lower, and all is good.

    At no rise, focus on the top third line and you're about right.

    Now switch to a distant landscape. WTF! Still at F8, focus on the centre of the frame and the edges are a bit fuzzy. Focus on the edges and the centre is really quite fuzzy. Focus on the right or left hand third, all is acceptable. Then the madness starts: focus on the bottom third line, even though the subject at that point is much near, and that point is sharp, the centre is sharp, and the edges are perfectly reasonable...

    So the general rule is: don't focus on the centre. More specifically, for shifts, focus on somewhere near to but not as far as the part of the planar subject which is furthest away from the nodal point.

    A really good technique, and on my lens this guaranteed to give you one good fame, is to set your shift, set your aperture, then focus one on each of the following spots:

    centre
    half way to the top third line
    the top third line
    half way between the top third line and the top of the frame

    No doubt time will refine my technique but blimey, this lens has a non-planar, non perfectly curved DOF which varies with aperture, shift and distance to subject.

    Bracket. But at least it can be done: here's a crop from the extreme top of a frame with ten shift, at 100% - and I must say, I can live with this!
    (focus was on the pale stone just under the base of the flagpole...)

    Thats pretty common with wide angle of view, retrofocus designs, and you need to keep in mind the total IC on the 24 PC makes it extremely wide angle of view. You see the same thing in wide tech or LF lenses if you look for them. (3rd order waveform PoF's, where sometimes the tail runs off to beyond infinity )

    It' precisely why I lauded Nikon's Live View for use with the PC lenses. I have my custom function set "B" dedicated to tripod mounted, live view capture: 3 second delay, AF on rear button only, center button jumps to 100% view to aid manually focusing.

    Re: 24mm PC-E Episode 2

    Here's a full frame at F11. This is about the best I can get, and to me is entirely satisfactory though clearly not perfect. Shoot at low ISO and you can even use a selective sharpening brush at the extremes, which I have not done here.

    POF was where the white blob is.

    one tip about the most wideangle TS lenses, don´t correct the lines for 100% I do always leave a tiny littly bit of tilted angle, this simply looks more natural. Additionally it helps with the cornersharpness .

    About the Nikon PC-E´s take care you have a version with intact mechanics !
    The locking screws at worn out lenses are lifting the front lens and leave it down when opened significantly. (this was also described in Detail by Diggloyd.com) of course this will result in moved sharpness planes and have worst possible results as a correct focus and tilt will be moved significantly !

    and further: all users of the 3 new PC-E lenses can be having a tripod clamp now. I´m happy to tell that we are selling a new product see images
    The price off germany will be 335,- € (+19% VAT if sold to Germany/ in Germany) plus shipment .

    Thanks Stefan,

    I totally agree and would do ths in practice, but it presented too many variables in a test situation. In reality I would probably get round 'difficult' shots by shooting with less shift and more camera angle, then partially correcting in post to allow slight converging verticals, allowing processing to take some of the strain off the shift performance of the lens, but I think my test today shows that with care, you can get perfect verticals in camera with full shift and acceptable resolution!

    Re: 24mm PC-E Episode 2

    I was nearly 100 % sure you knew this ! But maybe it helps some other people reading this.
    And yes- the postprocessing in combination with an optical tilt/shift lens can do astonishing things. I would even go as far as to say , nearly 90 % of what could have been done with a (full movement) viewcamera.

    Well, that's pretty much the most extreme shift I'd ever want to do. Even then, I'd only do it once in a blue moon. The top of the frame is pretty mushy as you say but in the overall scheme of things not too bad.

    Re: 24mm PC-E Episode 2

    So, fully shifted it's either a 44x36 or 24x56 frame? How hard would it be to rotate the lens and stitch a 44x56? Is that likely to run into geometric distortions (like barrel)?

    This looks pretty darn attractive...

    Hello Tim, I am sorry I didn't have time to do the promise experiment yet, however I posted some PC-lenses pics in my blog here, in case you're interested (note: they aren't of much use re: sharpness on shift though, they mostly show off some tilt )

    Jack,

    Thanks for the tip. It might be helpful to start a new thread on D800/D800E settings tips.

    Stefan, how about building a shift lens for the S2 since Leica is sitting on the idea?

    Re: 24mm PC-E Episode 2

    Some years ago when Leica was showing the first models( and a wood dummy of a TS lens) we were doing first talks with them, but we never got further than this as they announced they want to do it themselves.
