Agree I think he should give that lens away to his neighbor dust bowl desert dweller.The only convincing thing the WATE closeup shows me is that you need to clean off some of that AZ dust from the outside of that lens.
K-H,
That is a wonderful display of what this camera can do. I am amazed at the way it handles lights.

It was windy?Here are two shots and their crops from A7R + APO-Extender-R 1.4x + APO-Telyt-R 280/4.
First WO at f/4, then stopped down a tad at f/5.6. Here we go.
It was cold and a little windy when I took the shots across a canyon between two mesas.
I tried to focus on the word DIRECTV.
At f/4 I see vignetting that has nicely cleared up at f/5.6.
I also think I can detect a little more DOF at f/5.6.
Is this the kind of sharpness performance one would expect when adding an APO-Extender-R 1.4x to an APO-Telyt-R 280/4 on A7R?
How would this lens/extender combination perform on an M240 in a similar situation?
Do you think there is any shutter shake visible in the images? If yes, how do you notice it?
I appreciate your feedback. TIA.

Olympus OM-D E-M1 + 75-300/4.8-6.7 II @ f/5.1, ISO 200, 1/90 s handheld, FL in 35 mm film 200.
Sony A7R + Leica Vario-Elmar-R 105-280/4.2 @ f/4.2, ISO 100, 1/125 on tripod, FL 200 mm.
100% Crop @ f/8
EXIF reads:
F4.0 -> 1/400 sec, ISO 50 (left)
F5.6 -> 1/160 sec, ISO 50 (right)
So, the set up was a R to E adapter, 1.4X, and then the lens. Almost 400mm with a lot of connecting points. That'd be a mighty demanding set-up even if it were a straight 400mm.Thanks Bart. That's correct.
Those were the settings on the lens.
(I didn't bother to add the 1 f-stop for the 1.4x extender)
I didn't notice any wind for the first shot, but did notice a wind gust for the second shot. Aside from the wind induced vibration is the overall performance what you would expect? Thanks again.
Hi K-Hawinkler,
Thank you for this very interesting comparison : would it be possible to get a 100% crop of the E-M1 results as well ? I don't see much difference between the two shots at the reduced size you have shown. And the fact one can more easily shoot the MFT system handheld is a big plus.
I own an E-M5 plus an EOS-6D and was first interested by getting an A7 to finally be able to shoot my Zeiss Contax G lenses at their real focal length. I did even sell my M6 and 35mm Sumicron in order to fund that (yet kept the 50mm F1.4 and 90mm F2 both pre-aspheric). But the short flange distance have the effect I feared when using wide angle RF lenses. So this has considerable tamed my enthusiasm.
So for the moment, I have an appreciable credit at a brick and mortar camera shop, but have put everything on hold.
Don't you fear that your E-M1 will remain on a shelf now that you have an A7r ?
Correct.So, the set up was a R to E adapter, 1.4X, and then the lens. Almost 400mm with a lot of connecting points. That'd be a mighty demanding set-up even if it were a straight 400mm.
Yes, I have, but only for birding.Have you ever considered a Wimberley head? I had a 400mm I couldn't get a tack shape image from until I got one of them. But maybe that was just me.
Excellent points. I agree.Curious why you used ISO 50 which is a pulled speed, and not optimal? I think 50 is okay in the studio with very controlled light, but not so sure it is for ambient ... plus you could get the shutter speed up a bit.
Indeed, a pleasure it is and I feel very privileged having acquired some of these special lenses recently.As to your question ... I wouldn't have a clue what to expect. I've never had the pleasure of using such a stellar long lens :thumbup:
