    Jono, not sure if you saw that I posted a load of 35 Lux FLE test shots… my feeling was that it was a 'not quite' due to colour cast issues, and that F5.6 for a lazy eye is just about OK but that diffraction is too notable above that to feel that one is getting value for the sharper edges...

    Jono,
    The Summilux 54 FLE is a lovely lens, unfortunately I tend to prefer the 50 mm as focal length and therefore I am not using it as much as it deserves.
    Also on the Sony A7r it performs beautifully, as far as I have seen insofar.

    @rayyen:
    That's a fantastic "product photo"!!
    Beautiful combo, you should offer it to Sony
    BTW, love the red hand-strap - what is it??

    Thank you. Extremely helpful. Especially interesting is the 24 elmar (a lovely lens). How did the 35 lux perform?

    .......... And a big welcome, this is a civilised place! (Well, usually!)

    All the best
    Thank you. I have a half time test in 2 days, of some training I do right now, so not too much time right now to post.

    Will come back next week ;-)

    Hey !
    I dont own an AF-Adapter so I use a "Kipon" one from ebay.

    Hi Tim
    I did indeed see and examine your results.......... But I know you aren't fond of the lens anyway, so I was wondering what Ario thought.

    Just this guy you know

    Chromatic Aberations are higher on the A7R !

    (...)

    A7 and


    Contax G 28mm
    A bit of colour cast but smearing wide open
    Much better @ 5,6 but still not that nice...

    Contax G 35mm
    No colour cast and minor smearing wide open
    perfect at 5,6

    Contax G 45mm
    No colour cast and a tiny bit of smearing wide open
    perfect at 5,6

    Contax G 90mm
    No colour cast and no smearing wide open
    the same @ 5,6

    Hope this is helpful :-)
    It is very helpful. Many thanks for sharing your experiences. I'm particularly interested by your tests with the Contax G lenses. Since I own the 16mm, the 21mm, the 28mm, the 45mm and the 90mm.

    I know the 16mm will block the shutter on the A7s, too bad. I wonder what the 21mm will produce, whether it will be much worse than the 28mm or not.

    For those Zeiss lenses, would you get the A7 or the A7r ? I'm a little reticent to the size of the A7r files. But on the other hand, the 45mm and 90mm should shine on the A7r..

    Re: Fun with the A7/7R

    There are some fine examples with G45 on A7R. My guess is that G90 will require some caution, because it is a reavealing lens and A7R an unforgiving camera, so good shooting technique is required.

    Re: Fun with the A7/7R

    Well, Mr. Schierbeek is on his way back home. I tried his FE 35/2.8 briefly. AF is very fast in indoors (not very bright light) as well. Tomorrow he will have his A7R and will post pics from it.

    The Contax 18/4 is a fabulous lens on the A7R. He made several pics with it and perhaps we will get to see some samples soon.

    Fantastic person!

    MMmm what do you mean exactly ? That one need very steady hands or a very fast speed ? Or do you mean that it would be tricky to focus correctly ?

    Do you think that the. A7 would be more forgiving ?

    Re: Fun with the A7/7R

    I have that lens. The adapter (Metabones) that came with it makes the focusing quite an experience. It is easy to work with (if one gets used to the adapter) and is very sharp by f/5.6. It is a bit too sharp and the boket isn't like a classic Sonnar.

    Things that people keep forgetting is that the A7R is more forgiving than even the NEX-6, is far better constructed than any NEX, heavier and is easier to hold more securely.

    Well, 36Mp of resolution is going to show a lot of detail, and 100% magnification will be more than on A7, so, yes, it will be more demanding. You won't get away with almost-good focus, or almost-stable handling, or almost-good lenses.
    Similarly, many people complained about Nikon D800 early on, and now much less so. What needs to be done to get sharp pics from that body has pretty well become a fact of life. The same happened with NEX 7, and it took a while, and I expect a similar learning curve with the A7R.
    So, why single out the G90? Because a longer lens needs more stability, and because focusing the Gs (I have a Kipon) isn't as smooth and delicate as a Leica M or Zeiss ZM.

    Hey,
    I don't own the 21mm so I can just guess.
    Normally the 21 was always the same as the 28 or worse so I have no hope for using it on either A7s.

    My opinion on A7 vs A7R in general :
    Get the A7.
    It is
    cheaper
    has faster flash sync
    more fps
    build feels the same as the A7R
    same weight as A7R
    picture quality is the same (even though the A7R has more pixels)
    usability is better with RF lenses. (much less hassle with magenta cast)
    smearing seems to be the same with both A7s
    AF is a tiny bit faster
    smaller file sizes

    I will keep my A7 and my friend with the A7R is about to send it back and getting a A7 too.

    Re: Fun with the A7/7R

    First tests with the Canon 24mm T/S mkII lens.
    I much prefer the overall look of the Sony compared to Nikon D800, colors, mid tones are a lot more in my taste.
    But not sure to like what I see at pixel level. Some soft micro contrast mixed with jaggies from LR 5. Really not impressive. Don't know how much of this is related to the Canon lens (that is supposed to be very good) but I suspect LR raw conversion not being optimized at all yet for the Sony files. Image data converter from Sony gives better results at pixel level for what I have seen so far. But these really are 1st tests.
    Did anybody else made the same observation ?
    (Unfortunately I have no other lens yet to eliminate that variable).

    Full image:



    Crop 100% from LR5 with very conservative sharpness parameters (31/0,7/40/20) (clarity + 10) no photoshop



    See jagged edges on the background colums and on the red plastic thing (focus on that red piece @f8 on tripod using live view)

    Now with Sony IDC:



    Sharpness settings are more pushed but less jagged edges are visible.

    Re: Fun with the A7/7R

    Back home after a pleasant (Photo) visit at Senor Iyer.
    So nice to have a preview with his new A7r. Couldn't wait until tomorrow.

    Nice camera! Here are some snaps with 2 C/Y Zeiss lenses taken on a walk with Vivek. Look @ the ISO figures. Couldn't do it with the NEX-7.

    Will be continued tomorrow if the postman can find the right door.

    Could you play with the contrast (LR, lowering the contrast)) and see what happens? I know that the EOS lenses have higher contrast (to compensate for the thick layers on their sensors) than most other lenses.

    I am keeping my A7R and am glad that I went with this than an A7 (still can buy it but very unlikely). Here is why.

    Re: Fun with the A7/7R

    And would be almost the same on A7. lol

    36 MP to 24 MP sounds awesome but in reality this is kind of a minor difference.
    6000*4000 to 7360*4912 sounds not too awesome, isn't it?

    I really thought the difference would be much higher but reality struck me before I bought from Sony, haha.
    But if the A7R works for you, everything is good. It is a fine camera indeed.

    Humm, in fact the pictures do lack some contrast in LR. The micro contrast is not very highly set (clarity +10). The problem at pixel level I see seems more related to the 'detail' cursor of the sharpness tool. Only way to reduce jagged edges significantly is to put it to '0'. Thin wires on another picture also clearly shows those jaggies from LR, better controlled in Sony raw developer.

    While I have yet to take any images of my own with the A7R, the A7 and A7R samples I've seen, downloaded and worked with lead me to a different conclusion. I think the examples below, converted from RAW test files obtained from imaging-resource.com, speak for themselves.

    From my point of view, the decision between A7 and A7R depends on whether you have a need for 36MP (now or in the foreseeable future), i.e. whether your photographic subjects can benefit from the extra resolution (which IMO is real, and is due to both the higher MP count as well as to the lack of an OLPF).

    File size and associated processing speed are fast-moving targets: hard drive capacity and CPU performance are growing at a steady pace, and a file that you may consider large and somewhat unwieldy to process today will be the norm tomorrow. For photographers who process very large numbers of images on a regular basis, this is certainly something to consider, but for the rest of us probably much less so.

    I am really poor when it comes to PP. Despite the rudimentary PP I do, I must say that I never liked the clarity tool of LR. I also hope that the LR5.3 RC will improve with the final version.

    Fotoingo, There are other factors as well. Run the camera for 1 hour continuously and see where the heat gets dissipated. The whole of the front metal plate of the A7R gets warm. I am not sure how well that happens with the A7.

    The crop shown is less than the pixel count differences between the 7 and the 7R.

    Oh, I forgot to mention that the adapter used was a Hawk helicoid adapter, the one that apparently attracted big threads and discussions (elsewhere) on how unsharp it would make the pictures because of wobbles. :-)

    Re: Fun with the A7/7R

    Thank you very much, Vivek and Michiel, for your fascinating images. I wonder whether you could answer a question. Both of you have shot NEX cameras in the past, using relatively quiet shutters. In your street photography, did you notice whether the somewhat noisier A7R caused your subjects to react differently, relative to how they reacted when using the NEX? Nettar

    How about the shutter sound and performance. Doesn't the A7r have a different shutter design from the A7. From what I have read the A7 allows for electronic first curtain, which in turn not only reduces vibrations, but also has faster shutter response time. Also the A7 shutter is meant to be less audible than the A7r

    Anyone tried any WA Leica R lenses yet? Saw the 21-35, but how about fixed WA?

    Nettar, When I first met Michiel, I handed him the A7R and the couple shots he was taking (I was ~1 meter away), I could not hear the shutter. While I take a shot I always hear it very distinctly.

    For this shot: http://www.getdpi.com/forum/550498-post343.html

    I did not hear the shutter (approaching tram) at all. Hope, this gives an idea.

    My testing with the NEX-7 showed that the electronic first curtain certainly does help reduce vibrations. However, I found the difference to only be relevant when shooting from a tripod at shutter speeds between 1/f and ~1.5s. Shorter and longer exposures are largely unaffected. Since the A7R uses a different shutter mechanism, its effect on camera shake will likely be considerably different. Whether that's for the better or worse is impossible to tell without testing...

    From my point of view, the decision between A7 and A7R depends on whether you have a need for 36MP (now or in the foreseeable future), i.e. whether your photographic subjects can benefit from the extra resolution (which IMO is real, and is due to both the higher MP count as well as to the lack of an OLPF).



    File size and associated processing speed are fast-moving targets: hard drive capacity and CPU performance are growing at a steady pace, and a file that you may consider large and somewhat unwieldy to process today will be the norm tomorrow. For photographers who process very large numbers of images on a regular basis, this is certainly something to consider, but for the rest of us probably much less so.





    These tests have to be so secure to really tell the truth. To me it looks like they have diffrent focus points. How can it be that the top of the third layer of cloth in the A7r picture looks worse compared to the A7, the second layer better and the top layer much better?

    Pixel peeping it's hard, also because of the different magnification because of the difference in amount of pixels between the 2 cameras.

    Re: Fun with the A7/7R

    Hi Angy,

    I did indeed mention the jaggies further up the thread and postulate that it relates to the LR 5.3 RC processing. I can even see them on a Retina at 1:1 so it's not just a 100% thing and they annoy me. I agree with you that the pixel level detail is not as stellar as I expected (why I suggested to Jono that he might wait but as usual he ignored me!).

    As for the mid range, maybe, I'm not sure, but it does look as if they might have put some more 'math in the middle' because the shadows aren't as clean as a D800… which could also be because the sensor is on all the time and therefore on average warmer...

    I much prefer the overall look of the Sony compared to Nikon D800, colors, mid tones are a lot more in my taste.
    But not sure to like what I see at pixel level. Some soft micro contrast mixed with jaggies from LR 5. Really not impressive. Don't know how much of this is related to the Canon lens (that is supposed to be very good) but I suspect LR raw conversion not being optimized at all yet for the Sony files. Image data converter from Sony gives better results at pixel level for what I have seen so far. But these really are 1st tests.
    Did anybody else made the same observation ?
    (Unfortunately I have no other lens yet to eliminate that variable).

    Again, it is measurable, but whether it is of practical significance is debatable.

    Agree.

    I must add here that those who want to do tripod mounted work should consider contacting places that offer modifications (active cooling). Creative amateur astronomers have done wonderful things with their Canon cams. I have a project ongoing for this to suit my needs.

    I fully agree. Such tests are challenging even when comparing the same camera/lens combination to itself. OTOH, despite the slight difference in focus points between the images, I would say it's undebatable that the A7R image shows significantly more detail and to me, it also shows more 'presence' and three-dimensionality.

    Looks like it in the clouds...so go to PS and use the color sampler...read on lt and rt in the sky/clouds and in the trees....should show a shift in R values if this is so.

    The A7r leaves more room for cropping.

    The A7R image seem to have sharpening applied to it. There is also more contrast in the A7R image. That might be in-camera and to do with differences in exposure and optic. Those alone will give the appearance of it being "better" than the D800e. That can be be changed in Photoshop in seconds.

    I don't think your conclusion is "undebatable."

    We were discussing the difference between A7 and A7R. The same lens was used on both cameras. I provided the D800E image for reference only. A valid comparison is impossible in this case, since a different lens was used for this image. The same sharpening settings were applied to all three images in LR, and WB was set using the color checker present in the test scene. Otherwise, all settings were at their LR defaults.

    Edit: I attribute the increased contrast in the A7R image to the difference in sensor toppings between the A7 and A7R, but that's just a guess.

    Bob,
    I had already done that. I'm not seeing the shift on my NEC. I will re-calibrate it tomorrow and see if I can see it. The values on the left were 181, 189, 206. On the right 170, 180, 199. About an inch lower on the left 165, 179, 206 and on the right 145, 163, 196. I am thinking that if this is significant, it is indicating that my sensor is not sitting straight. I had a different lens and adapter on the camera today.

    I really doubt that this is shift caused by the lens or adapter.

    Cindy, if you have doubts, just take two pictures back to back, one with the camera upside-down.

    The sky is not perfectly even in terms of color, people. If there was no measurable difference in color between over here and over there when the sun was at an oblique angle, that's when I'd get worried!

    Which is why I suggested earlier to shoot a white target

    Re: Fun with the A7/7R

    Taylor, I would not have noticed it until it was brought to my attention yesterday. That is very sensible advice that you have given me. Before I put this to rest, I am going to shoot a white background as Ron previously suggested, and I will turn the camera over as you suggest. Then I can go back to enjoying this camera.

    Re: Fun with the A7/7R

    Hi everyone,
    I have been busy this week-end shooting the A7R and a HOST of M lenses...I am satisfied that everything 28 mm (summcricron) and above would suit my purposes, and in particular, the longer lenses work great, with precision focus.... I am definitely getting one, at this point, not that there was really any doubt...

    I plan to post my comments and thoughts along the way, but I am impressed....it's not, by any means, a faultless camera, but the sensor shines in many regards!
