    Manual focus lenses


    Poor man's Noctotus

    The AI-S Nikkor 50mm f/1.2 wide open - here on a 12Mp cropped DX sensor camera (D300, it's all I've got for the moment).

    Still-life with reference to Jorge's Otus illustration .-)


    You can take a closer look at the RAW file to judge aberrations and sharpness (or lack thereof) etc.

    Jack, if you like the AI-S Nikkor 50mm f/1.2 you will also like the AI-S Nikkor 105mm f/2.5, I think.

    Here the AI-S Nikkor 105mm f/2.5 wide open - and again on a 12Mp cropped DX sensor camera (D300).

    Steen,

    I agree it's lovely, but I already own it's younger but larger brother, the 105 DC -- same basic design as the 2.5, but slightly faster at f2.0 and then has an adjustable front group for varying the spherical ab's effect at the focus plane. (It also adjusts the focus plane at the same time, but the effect is stellar when not overdone.) Also a laser stopped down a few, though slightly lower contrast than the newer offerings. It also has the built-in retractable hood --- really like that feature from the bygone era.

    Anyway, if you like your 105/2.5, you really should try the 105 DC! It is one of my favorite lenses...

    Re: Manual focus lenses

    Just for thread posterity, here are a few from the 50/1.2 wide open as well -- all from the D800 and all hand-held:



    And a center crop from that one for pixel performance:



    The lens obviously has a ton of falloff wide open, and the effect is exaggerated when the key light is in the center frame -- note there is no added vignette in post in these images:






    Finally, an example that was an attempt to show what IMO is outstanding (even though a little swirly swirly -- which I happen to like) front bokeh:



    And then a center crop at the focus plane from that image for pixel performance -- I was pretty impressed with this distance performance at f1.2, even if it is just center field:

    Re: Manual focus lenses

    And again for thread posterity, some sample 105DC images -- wide open at f2.0 and also f2.5 to compare more directly to the 105/2.5. Processed in C1 with identical base settings, only difference between images is aperture and ISO. Focus point was center of yellow flower. Posted on top of each other for easier comparison, both with zero DC offset (sharpest setting):




    And crops for reference:




    While DoF does not appear to change much in the main image, you can see it in the crop. Also a few other notable observations are 1) how much it sharpens up at the pixel level stopped down just that 2/3 stop -- it is initially sharp, but gets notably more so just 2/3 stop down; and 2) the change in falloff is relatively major, close to a full stop, lifting foreground corners on tabletop.

    Re: Manual focus lenses

    Evening gents (and ladies)

    Great recommendations, I now have an offer for a 105 f2.5 plus, I know it's not a manual focus lens exactly but just got a great deal on a 200 f2 that should be arriving next week, very excited! It's a version 1 but I don't think that'll be an issue, it looks new!

    Thanks for all the advice, hopefully I'll get lots of pleasure from these new purchases.

    Re: Manual focus lenses

    The 105 DC is very good but much bigger than the 105 f2.5 AIS. I so love manual focus lens !! If someone have one 105 f2.5 AIS in excellent condition and want to sell it, let me know (would need a little fly over Atlantic ).

    I'm just lucky enough to have found a 50 f1.2 brand new under Nikon warranty some months ago but I would like to had a 105 f2.5 AIS to my collection.

    Yes, if size and weight is important, then the 105/2.5 is a good choice. Both the 105DC and 105/1.8 are about 1cm wider, 2cm longer and weigh about 160 grams more. But if you look at Photozone and Photodo, you'll also find that both are a little better performers.…

    Manual focus lenses


    ok, Jack, I surrender
    that 105mm DC optic sure looks sharp even wide open
    very nice indeed

    and your 50mm f/1.2 samples from the woods are so magic and dreamy
    I am still thinking about these nice AI-S optics mounted on a Df body
    if only the Df wasn't so ridiculously overpriced
    but perhaps it can be had at a more reasonable price in a couple of years

    Re: Manual focus lenses

    Steen -- funny you mention the Df for the 50/1.2… Right now, it's basically permanently bolted to my D800 non-E, so I have been thinking the same exact thing with a Df -- and a chrome one, of course!

    Seriously, the 105DC has a few things going for it. Firstly, it does have AF, albeit slow and buzzy, but it works well. Secondly it's built like a solid piece of industrial equipment. And lastly of course, you can vary the bokeh effect and bias it to the front or rear depending on your needs -- though admittedly I almost never use this feature, preferring the natural balanced bokeh as it is. One other little tidbit is the DC is actually a G-B Achromat with the R channel focus slightly behind the B and G -- this supposedly is one of the reasons it renders human skin so well…

    Some from this afternoon: Nikkor-S auto 1,4 from the early 60's on the D800, all at F1,4.
    I love this lens, especially for video.

    whoa, some absolutely wonderful aberrations there, Y Sol

    love it, and your beautiful captures as well

    I wonder if it is still possible to get an AI kit and have it mounted somewhere in Europe ?

    Re the 50/1.2 lens.....I found this site with full size images/examples.

    Full-size sample photos from Nikon 50mm F/1.2

    The thought of using this lens on my D700 really interests me, although in truth, for the kind of photos I usually take, the Zeiss 50/2 Makro-Planar makes more sense.

    With a little filing on the metal ring around the rear element, they can be made to work. I have such a lens, and use it on my D800. I also own the Zeiss ZF.2 35/1.4, and given the number of other ZFs I have, I might sell the Leica.

    As re this Sigma 35, it's quite possibly too darn good wide open to deliver what I'm looking for, and I may in fact be stuck going after a 35 Lux R and converting it…
    I am a bit surprised that no one mentions the Zeiss 35mm f/1.4 Distagon in this thread. Beautiful boke, some aberrations, but very worth it. Personally, I find the boke in the Sigma a little "thick" and unpenetrable. Hard to describe properly. The f/1.4 lens is very different than the Zeiss 35/2, less vignetting, finer detail rendering, not so crunchy or punchy, more subtle.

    Re: Manual focus lenses

    Whew, I have to find them! I am between two computers right now, and these days the good light is from about 12:30 to 12:38, but I should have something somewhere...

    And this is one of the reasons I have some misgivings about my new A7: no EXIF. In the future, I will not be able to find anything after the fact.

    Here is a boring comparison between the Leica and Zeiss ZF 35mm f/1.4 lenses, over on that other forum:

    leica vs zeiss - FM Forums

    I will see if I can find some more beautiful photos.

    Re: Manual focus lenses

    I have copied the post here, although it might be worthwhile heading over anyway to read the comments.

    Well, I shuffled my day today and went out explicitly to test the Leica Summilux-R 35mm f/1.4 against the Zeiss Distagon 35mm f/1.4 ZF.2. The light today was very flat, but bright enough to provoke some CA in branches against sky. I tried to shoot at various distances, focus in various parts of the frame, and also tried to provoke some 3D (the latter largely without success in any significant way).

    Keep in mind when reading this that I would rate both lenses as being among the best I have ever owned, both better than 9/10 (but both not reaching 10/10). Also:

    • This light is only one kind of light. Other kinds might yield different results.
    • This is only one style of shooting. Other styles yadda yadda.
    • I have only one copy of each. I believe them both to be good, but it is possible that one is better than the other.
    • My Leica-Nikon replacement mount appears not to quite reach infinity. It did on my D3, but not on my D800. I will have to adjust it.
    • I did not compensate for slight colour differences, since I do not want to fiddle much with Lightroom, for fear of introducing bias.
    • The focus point moves around a little, despite an effort to use the same focusing spot for each shot. I think in one shot it may even move a lot, due to operator error.


    I would summarise the lenses as follows (some of which is personal, and thus debatable):

    Mechanical:

    • The Leica is smaller (half the volume perhaps?) and has a built-in hood. The weight is not so different though.
    • The D800 interacts fully with the Zeiss, but does not even know when the Leica is mounted. I set up a non-CPU lens slot to get EXIF.
    • The Zeiss focus movement is lighter and smoother, but the travel is much shorter, and thus a bit less accurate.
    • The Zeiss focuses to 29cm or so, the Leica to 50cm or so.


    Rendering:

    • The Leica has more resolution near the middle, less near the edges, when near wide open. In other words, the Zeiss's sharpness is more evenly distributed.
    • The Leica can have kinda messy corners wide open.
    • The Zeiss appears a little warmer, but see caveat above.
    • The Zeiss has a fair amount more CA, as much as double (measured by width in pixels in OOF regions).
    • The Zeiss has higher contrast, i.e. the Leica has more detail in the shadow regions.
    • The rendering characteristics make the Zeiss easier to see focus accurately with.
    • Both have field curvature, the Leica more, and I think in opposite directions. I am not sure if I am judging this right due to limitations of the samples I have available.
    • The Leica has quite a bit more vignetting, but it is often attractive.
    • When out of focus, the Leica gains "haze", the Zeiss "softness". It is hard to describe what I mean by this, but I see a distinct difference when focusing with live view. This helps make it harder to see if the Leica is in focus.
    • Stop for stop, the Leica exposes a tad darker (1/4 stop maybe), and carries more depth of field. The further away from the plane of focus, the more similar the amount of blur is. The Leica's DoF region is somehow fatter in the middle, but overall similar.
    • The Leica's depth of field rolls off slower (probably another way of saying the same thing).
    • The Leica has a couple of mm shorter focal length. I do not know which is closer to 35mm.
    • The Leica is sharper when stopped down. In fact, it is bloody sharp. The Zeiss is only very sharp
    • The Leica has noticeably less distortion.


    It is not possible for me to overstate how much of this is just small tendencies, nothing that I would really notice, except by comparing directly. Both lenses are awesome, really amazing glass. A few of the differences are larger. Overall I would say that the Leica is better optically, but this does not necessarily make me prefer it. I am still undecided, but leaning very slightly towards preferring the Zeiss for its overall balance of pros and cons compared to the Leica (before seeing the results today, I preferred it even more, but the Leica is very impressive). Note that I own 6 other Zeiss ZF.2 lenses, so the Zeiss fits better in my collection. I am also a bit lazy and prefer electronically coupled lenses.

    Here are some samples to demonstrate some of these points, Leica always first. These are all un-processed, other than importing into Lightroom 4.2, occasionally bumping the Leica exposure one notch, and then exporting. I do not know if Lightroom auto-corrects the Zeiss...

    Not all have identical focusing points, so don't obsess about small differences (hard not to do when all there is is small differences ). Also, most are unfortunately in portrait orientation, so I cannot make them as large as I otherwise would.

    I do need to go out one day when the light is harsher, and I also need to compare skin tone rendering. I think the Leica may win both of those contests.

    Let me know if you want me to split this up a bit. These are shots I have previously selected for posting, but if you feel that there is something specific missing, I could take a look and see if I can find something. EXIF should be present, all are on the D800.

    I just got the 105/2.5 today, did some basic testing and I'm very excited to see in person what it can do! I'll post some pictures once I get home (after New Years),
