    Thanks Carl. Your shot is terrific, stunning indeed.
    Which camera/lens did you use?
    What time of year did you visit?

    Thanks, I think that was in September and the camera was a Canon 10D with a Canon 20mm lens.

    Re: A7r - and why I'm keeping it ...

    Got it and have been charging for nearly 4 hours so far. This is a worse wait than waiting for UPS to come with the camera!

    I have the Metabones M-E and R-E adapters. Hope they will be OK.

    Now to my dilemma, like most, what lens do I try first? I'll start with my cheaper lenses.

    R 15/2.8 probably
    then Contax G 28/2.8
    then R 21-35
    then WATE-looks good from K-H
    then 21/3.4
    then 21/1.4
    then Contax G 21/2.8
    then 24/1.4
    then 40/2.0 C Summicron
    then Contax G 45/2.0-looks good from fringe

    My backpack is full.

    Come to think of it, I will run out of daylight before I can get through using just 2 of those lenses. Oh well, tomorrow is another day. Yeah!

    Re: A7r - and why I'm keeping it ...

    One word-fantastic!!!!!!!!!!!!!

    I have seldom enjoyed walking around with my R lenses more. The Contax G lens (although the Techart adapter leaves much to be desired for me) worked, but stutter hunting for focus was annoying from time to time and of course the FE35 which I am now happy I got to be able to experience this cameras AF first hand. I like it. The shutter is a bit loud, but it does not bother me and some candid shots no one even turned around even though I was 2 meters behind them.

    Started with the R 15/2.8 and Metabones adapter. Corners look great on LCD. Played with the f stop in M mode to get what I wanted (I guess) since I have not read or digested the thin manual yet. All this done hand held. Wish I could select speed in M mode. Oops sorry, I have not read the manual yet.

    G 28/2.8 adapter not confidence giving, but AF works OK.

    R 75-210 on tripod with MB adapter and using the adapter QR on my big RRS ball head. Used 7x zoom feature for first time here, red outlines (same as on my M240. but seem to be much thicker and easier to see for my eye), then went to 14x and then I see why I might need it at 210mm, but worked like a charm as I could see my first focus was not pin point on. Great feature. Also want to mention the balance even with this longish lens was great for me and the smallness of the camera is to my liking. I did not miss my M while out with this camera. Frankly, with all the R lenses I have I would not need an M except for the 18,21,24 and possibly 35mm M lenses I own.

    Have not figured out how to make the focus patch smaller, but that will come.

    The EVF viewing was no big deal for me since I have been using the M240 EVF for thousands of shots and it just plain works for me. Sometimes I wonder if we all nit pick way too much instead of enjoying what photographic engineers have designed for us.

    I am not into beta software so cannot look at these on my monitor I guess and have no idea where to get a plug-in that some have discussed as helping.

    All in all IT'S A KEEPER.

    Glad you like the little camera, Lou.
    As for processing the files: I'm using Sony's IDC, then converting the RAWs to 16-bits TIFFs and then into C1. Not ideal but for now it's fine.

    Kind regards.

    Re: A7r - and why I'm keeping it ...

    Besides the Novoflex adapters I really have been enjoying my Phigment LM-NEX adapter.
    Here are wide open WATE shots with the latter adapter on A7R.

    A7R + Phigment Adapter + WATE @ 16 mm.


    A7R + Phigment Adapter + WATE @ 18 mm.


    A7R + Phigment Adapter + WATE @ 21 mm.


    BASED ON THESE TESTS I AM WILLING TO GIVE MY WATE ON A7R A CLEAN BILL OF HEALTH FOR NOW!


    Unfortunately the Phigment LM-NEX adapter seems to cause vignetting in the extreme corners with the Leitz Tele-Elmar 135/4


    whereas the Novoflex adapter doesn't seem to.


    I hope this will be easy to correct.

    I would love to see your comments and pictures concerning the Contax G lenses, especially the 21mm (it is not reported to do very well alas, but I would still like to see the results). Are you using a A7r or a A7 ? The A7 would probably be more forgiving.

    I am using the a7R. Tried the 28 yesterday and LCD looked fine. Have not yet hauled out the 21, but will probably tomorrow. All my adapters are Metabones.

    Today
    M 21/1.4
    M-WATE
    M-MATE
    R 80/1.4 maybe
    R 180/3.4 maybe
    APO50 maybe

    Cannot find the way to turn off as many in camera functions as possible. I am now shooting RAW+JPEG so at least I can see the jpegs.

However, the Summicron 35 asph and Elmarit 24 are not up to what I need. The 24 Elmarit @f8 and stopped down further is ok, but f2.8 and F4 are not satisfactory. The colors with the 35 Summicron are all over the place, I won`t bother with it on the A7r again. I`m interested in others experiences with 35mm RF lenses on the A7r. It seems the CV f1.2 35 does fine, but it is too bulky for my liking. I will try the Summilux 35 asph (not FLE) over the weekend, but do not expect too much after the Summicron 35 experience.
    Wow, this is a real bummer and quite surprising to hear the 35mm 'Cron ASPH is a no go. I have been testing my 35mm 'Cron, an older pre-asph version, and find it positively STUNNING on my A7R. My 28 'Cron ASPH, I don't like nearly as well. My old 90mm Elmarit is also fantastic. So it seems that the pre-asph Leica M lenses I own look much better to me than my one ASPH does.

    Let me get some stuff I shout yesterday worked up, and I can post some example photos.

    Yes the grip is great with larger lenses like most of them that were made for film cameras. Contax-Zeiss, Canon, Nikon, Leica R, all are easier to hold and handle with the grip. Leica M lenses & most of the Voightlanders I do not feel the grip is necessary myself, but your own mileage may vary.

    The grip does give the A7R a real "power camera" kind of look though, so I may just use it on mine all the time.

    Instead of 35mm/2 asph, either 35/2.5 Summarit or 40/2 M Rokkor.

    In place of 28/2 Summicron 28/2.8 M Rokkor.

    Plenty of choices. No one shoots wide open all the time.

    Samys Camera on Fairfax in Los Angeles had four grips as of Thursday. Not sure if any are still in stock or not, but they said more are on order.

    100% Crop, then reduced from 1500 to 1200 Pixel along a side.

    This was easy to focus, noticing the changing colors of CA.
    Zebra also helped.

    I shot this handheld from inside a car, engine running, open window, heating on full blast!

    Wide open all the time? Well, not all the time but some of us do more than we don't

    I haven't tried those Rokkor lenses yet. Will try to hunt one up and do that, thanks for the suggestion Vivek. Looking at all the examples here, that WATE also is looking like a good investment to consider…. but man, what a cost!

    Re: A7r - and why I'm keeping it ...

    Chuck, I have a whole set of explanations behind why the M Rokkors work better but will have to do some measurements and such before expounding on it. You will be very pleased if you try them.

    Yesh, i would like a trielmar as well.

    Re: A7r - and why I'm keeping it ...

    It may be interesting to compare a really long lens on both D800E and A7R.
    Why not the Leitz 560/6.8 (it's wrongly labeled 560/5.6) with Novoflex Slow Focusing Tube.
    Here is one with Olympus OM-D E-M5.


    Now with my additions to avoid oscillations and vibrations to make it useable and with Sony NEX-7.


    The Novoflex Slow Focusing Tube is interesting as it requires a Novoflex Universal Bellows mount.
    The following adapters attach to it, namely:

    • NIKA Novoflex Nikon Adapter for 35mm Camera NIKA B&H Photo Video for attaching Nikon F cameras.
    • LEA-R Novoflex Leica R to Leicaflex SL Adapter for 35mm LEA R B&H for attaching Leica R cameras.

    This image was shot wide open with a Nikon D800E attached to the Novoflex NIKA.

    No vignetting to speak of.

    We might instead attach a Novoflex NEX/NIK adapter and the Sony A7R to the Novoflex NIKA. Shot wide open we get.

    Surprise, heavy vignetting is the consequence. Not good.

    Now let's instead attach a Novoflex NEX/LER adapter and the Sony A7R to the Novoflex LEA-R. Shot wide open we get.

    Surprise, surprise, no vignetting. Very good!

    Re: A7r - and why I'm keeping it ...

    Samy's at Fairfax in Los Angeles has the Sony a7 (and possibly a7R) on sale for 'no tax' through tomorrow.

    After fondling, er, assessing the ergonomics, I took one home. It feels like nothing so much as my Olympus EM5.

    I also took a look at the grip. I can see why some would like it or be attracted to it but I took a pass. When I want a big camera I will use my D4.

    IMO, Sony has got it going. I hope they keep pushing the envelope.

    I agree.
    Ergonomically to me it seems to be somewhere between my EM-5 and E-M1.
    But the A7R has room for improvement to reach the stellar E-M1 level.

    Many thanks Bart. Well, let's see. This is a ten mile distance shot on tripod. Focus was on upper meadow.
    One thing I have to change is to use remote triggering.

    Here is an image at 100% http://winklers.smugmug.com/photos/i.../i-drjVJ4P.jpg

    I also could use a better lens, e;g. APO 280/4 with APO-Extender-R 2x.
    What do you suggest I do differently? I always appreciate supportive advice. Thanks again.

    Re: A7r - and why I'm keeping it ...

    Here are some quick measurements I just did.

    Leica M to Sony E Adapter: Inner Diameter Measurements

    Phigment ............ 30.87 mm
    Hawk's Factory .. 36.01 mm

    Fotodiox ............. 41.54 mm
    Novoflex ............. 41.66 mm
    Fotodiox Pro ...... 41.74 mm
    Metabones black 41.83 mm
    Metabones red ... 41.84 mm



    The inner diameters are not uniform. They vary a little bit.
    I measured the largest diameter of each adapter I could find.

    Based on these measurements my Phigment and Hawk's Factory adapter are too small for FF.
    I have found major vignetting for 90 and 135 mm focal length for the Phigment but not the Novoflex adapter.
    Phigment LM-NEX: Electronic Leica -> NEX Adapter - FM Forums
    The lasted Hawk's Factory adapter inner diameter is now reportedly 40.00 mm.

    The diameters of the other adapters seem fairly close to each other.

    Thanks for posting these measurements, Karl-Heinz. Might be worth while posting this in the adapter thread, too.

    Thanks. I agree, together with Paul Habsch's explanations of phigmenttech.ca that he posted here.

    Leica User Forum - Einzelnen Beitrag anzeigen - The Sony A7 thread [Merged]

    Somebody else also posted measurements for the Voigtländer adapter here.

    http://www.l-camera-forum.com/leica-...-post3682.html

    Again, as with the Phigment adapter, the plastic circuit board has a narrower inside diameter as the wider metal part.

    Re: A7r - and why I'm keeping it ...

    This evening I had time to shoot the Sony A7R with the Leica Vario-Elmar-R 1:4.2/105-280 wide open and an Novoflex adapter on a tripod.
    Facing away from the Sun within a matter of just a few minutes colors changed
    from this to this . The last
    image was taken in the same light with the Universal Lens Calibrator from Capture One Complete.

    These images are OOC JPGs and only reduces in size, no further processing. AWB was used.

    Facing towards the Sun I captured these spectacles.

    The intensity and fidelity of the colors are truly amazing.

    Re: A7r - and why I'm keeping it ...

    Here is a shot with my Sony A7R + Leica WATE 16-18-21/4 @ 21 mm, reflecting pretty well what I saw with my eyes. Image not cropped, but of course downsized.


    Now let's make the image waaaaay too bright. Image still seems to be fairly well behaved though.


    So far my Sony A7R + Leica WATE 16-18-21/4 seem to have passed all my tests with flying colors!

    Leica WATE - Universal Lens Calibrator • Observation

    When I used the Universal Lens Calibrator ULC from CAPTURE ONE COMPLETE for the Leica Wide-Angle-Tri-Elmar WATE 16-18-21/4 lens on a Sony A7R camera I noticed the reference image was asymmetrical. Not good!

    Hmm. CAPTURE ONE COMPLETE has ULC Tips for use. Simple use 1 tip states: "When taking a reference image, the board should be as close to the lens as possible. If possible, remove the lens hood." Hmm.

    Well, the problem with the WATE is that the front lens element protrudes for 16 mm focal length if one removes the hood. Removing the hood makes it difficult to put the white plastic ULC board in front of the lens for accurate measurements. So I left the hood on.

    Next observation is the lens hood has a triangular shaped hole only in the upper left hand corner so that the hood doesn't block the view too much when used with a rangefinder. Could it be that this hole in combination with the white plastic ULC board gives rise to the asymmetry in the resulting reference image?

    Short answer: Yes, at least in part. Here is the proof for the wide open lens at 16 mm on A7R.

    First, reference image for unmodified hood.


    Second, reference image for modified hood, hole covered up with black electrician's tape.


    Voilà, asymmetry partially explained. However, there still seems to be another smaller component, probably due to other factors like adapter and/or lens.

    Next question, how should one use the hood in actual shooting, with or without hole?
    Answer: Better with taped up hole in hood, reflecting the reference measurement situation.
    But it probably doesn't make a significant difference. Reason being:
    Without the white plastic ULC board in front of the lens, light entering from behind through the hole doesn't get reflected back towards the lens.
    So, typical rangefinder use should be unproblematic. But when taking the reference image, the hole in the hood should be covered up with a non-reflecting material.
    That would be my guess.


    Here is an example, going back to the 16 mm image in post #57.

    This image was shot with the hood, the triangular shaped hole not covered up.


    Now we apply the first reference image that was generated with the triangular shaped hole not covered up.


    Finally we apply to the original image the reference image that was created with the hole in the hood covered with tape.


    In the last image the upper left corner is just a tad brighter, similar to the other 3 corners.
    One can easily see the difference in brightness by loading these 3 images into Preview and flipping through them.

    Re: A7r - and why I'm keeping it ...

    I agree with all the above K-H… of course, best practice is always to shoot the reference frame exactly as you'll shoot the shot itself but the 'hole in the hood' scenario is an exception. The other thing these perspex sheets can do, and you have to really look out for it, is catch light from their own sides: if the sun is glancing strongly off one edge it can transmit through the sheet and change the result quite strongly. It's a real 'gotcha' and one of the reasons to use the smallest sheet you can correctly deploy and to make sure that it is properly shaded.

    Thanks Tim.

    The sun from the side was the first thing I learned to avoid. That sure did mess up one of my first reference images. So, I now take these reference images in a place with an open sky and a building between me and the sun, or at a minimum i use my own shadow to avoid this issue.

    I also would like to thank you for having expounded repeatedly on this method. That's how I learned about it. It's easy to do and very convenient.

    Thank you.
    With best regards, K-H.

    A7R+Vario-Elmar-R 105-280/4.2 - Shutter Shock?

    Similar to post #74 of http://www.getdpi.com/forum/554027-post74.html one can also try to stabilize a Sony A7R and a Leica Vario-Elmar-R 105-280/4.2 when used on a tripod.
    The system then looks something like this, supporting the center of gravity..


    In order to answer the question how this setup performs I took photographs of a kitchen scale like this.
    Focus was near the top of the printed text.


    To cover a wide parameter set for exposure times I then took 54 shots according to the following table.


    The OOC JPGs from the A7R are available here: 2013-12-22 A7R Shutter Shock - winklers' Photos

    Please let me know if you see any signs of shutter shock in these full size images, arranged by ISO and aperture. Thanks.

    KH:

    That is a very solid looking support. I was looking at the RRS site a couple of days ago looking for a way to join the camera body to a lens foot mount to eliminate vibration. I was figuring a rail arranement might be available but what you've got there looks very custom and optimized for that lens. Was it custom made?
