A7M

[uhoh7]

Hi everyone.

My camera is back from Kolarivision with thin sensor cover mod complete. We have decided to call these the A7M A7rM etc. M is for Mod, M-mount and Michael who got the ball rolling with Kolari. The mod costs 400USD.

28 cron anyone?

You guys tell me, how's it doing?

Darn. When I saw the "A7M" title, I was hoping to see an announcement from Sony that they were going to produce a monochrome version of the A7.

Your pics look very good to my eyes.

What Gary said.

Here is the ZM35/2 which was also bad before:

these at f/5.6

I think we are seeing a big improvement, the M240 is still a bit better on the edges, I'd guess, but suddenly the camera is quite decent with these two lenses. Had it been this good stock I doubt I would have bought an M9. I love that camera and am glad I have it now.

AF seems to work fine with sony lenses as well.

Consider: an A7 used is 900ish + 400 = 1300 for a pretty decent M240 alternative.

Here is ZM18

this lens shows a big colorcast, as it does on M9 without correction. But edges are way way better.

Thanks. How does the 35 Summilux ASPH do?

Just send yours over and I can test it extensively :angel:

Don't have that one, Sry

But someone will. There are a number of these cameras out already and within a month I'd expect there will be 100.

Okay so I would be interested to see how the 28 summicron asph performs at f2 when compared to the M240.

Me too.

 

[jlm]

this is the anti-aliasing conversion?

It's an improvement but it looks like there still a color cast and smearing problem in the corners. I'm awaiting my full spectrum conversion on my A7R which will be here next week hopefully but I generally only use my rangefinder lenses that play nicely on my A7/A7R.

These lenses also cast colors on the M9 and 240, uncorrected.

If the smearing is only seen in the corners and it is more subtle, that is huge since it has been on the edges to date.

This is a 1300USD camera. It will outperform any A7 version with any lens designed for film. In the case of RF wides and the 50 Lux asph it will outperform them by a long ways.

It is not better than the M240. It is not better than the M9.

But it's pretty good

When you say it will "outperform", does it include moire?

BTW, is the dust shaker still there or gone? Can you post a picture of the camera showing the sensor? TIA!

No moire will be worse for sure. I just mean sharpness.

I think dust shaker is gone. I will try to get a pic of the sensor.

Also I was just peeping one of the 5.6 cron shots and could not find outright smearing in the corners.

But I need some long landscapes to really tell and we have bad weather here now.

Now, I could always be wrong I just report my impressions so far from testing and interaction with others. I'm not afraid to amend my opinion in future

Camera seems very much improved in sharpness, especially on edges. The FM thread has some close crops with and without Mod on 50 Lux asph which are crazy.

Also in case anyone wonders: I paid full price for the Mod. I have no business association with Kolari.

 

[Vivek]

I, for one, do not mistake your enthusiasm for a commercial plug. I applaud that you went through with the mod and thank you for showing the results.

The 28 M Summicron does look better on the modified camera with no obvious corner mush.

Hi There
It looks interesting BUT it was always at infinity that the M lenses performed really badly on the A7 . . . do you have any landscape shots near infinity?

 

[Vivek]

Were the Leica M lenses, especially the unit focusing ones, ever designed to be shot at infinity?

IIRC, Jack wrote (posted) a very nice and succinct piece about how the Leica M lenses shine at around 1/20 to 1/30X magnifications and why.

 

[cam]

Thank you for sharing. Have you noticed it behaving any differently with your FE lenses? I can see the sharpness, etc., just wondering if AF is affected.

Hmmmmmm… and still can't help wondering if anybody has done this mod on the A7S.

You are exactly right. The f/8 28 cron shot is at infinity. My was problem a storming coming in. I will be sure to get you guys proper infinity shots with my M wides.

Here is ZM 18 at f/8 inifnity. Hair on sensor confirms vivek's prediction we will see more dust

Yes, colorcast. This lens must be coded as 21/2.8 pre-asph to shoot clean on M9.

 

[iiiNelson]

I don't know if you use LR5 but if so do the lens profiles correct the images further for you? I know they helped on some M mounted lenses for vignetting and light color casting.

 

[Vivek]

uhoh7, If you have the NEX lenses 16/2.8, 20/2.8 (rear baffle removed) and the 10-18/4, it may be worth checking them out on the modified camera.
