Unless I'm misunderstanding what you have in mind, having a micro USB port on the adapter to enable lens data programming would either require multiple adapters (one for each lens), carrying a small notebook PC to enable lens changes in the field, or settling for a single lens/adapter combination for each photo session.

---------------------------------------------

I'd prefer that Techart offered a stripped down TAP without autofocus together with a new smartphone app that allowed one to manually enter and save lens data to be transmitted via Bluetooth. This would not only eliminate the wobble problem but would also allow quick and easy lens...Show more →

I guess, that what is meant is an M to E adapter that reads the Leica 6-bit code system and can relay that information to the Sony camera to write into the EXIF.

I don't think the Leica 6-bit code system would be so nice as it's only supported by Leica lenses (I have no Leica lenses, but I do have about 15 other M or LTM lenses). Something that would allow lens name and focal length and possibly other lens parameters could be nice if the adapter was still small and of high build quality.

Clearly you're not familiar with the Techart PRO because what I suggested has nothing at all to do with the Leica 6-bit code system. My simplified (no AF) but enhanced (additional EXIF data) TAP adapter would support not only M and LTM mount lenses but also other legacy lenses via X -> M mount adapters, as does the current TAP.

The 85/4 ZM is likely never to go away for me unless I stop hiking/climbing/backpacking for some awful reason. It's too good and too light weight.

Now if someone would just come out with a M to E adapter with electronics that will give the camera something to write EXIF data and correctly tell IBIS what the focal length is I would be in heaven. Put a micro USB port for lens data programming. Is that so hard a thing to do that no one has done that yet?

Most of us already have great 50mm and 85mm lenses and therefore adding a 65mm was unexpected. However, this lens is so good, I decided replacing both my 50 and 85 lenses for it.

The 50mm went out easily but when it was time to put the ZM 85/4 on the chopping block, I got cold feet.

For its IQ and Macro abilities, the CV 65/2 APO is really a steal for the current $999 price.

Did you already sell your 50lox Fred?

Please don't assume what I'm familiar with. Ok?

While I don't use the Techart Pro adapter myself, I know of its' functionality. The Leica 6-bit code system could be applied any way you want, even with any legacy lens. Adapters are cheap and could be six bit coded any way you like, and you could assign to a 6-bit code reading adapter any lens you would like according to your puroses instead of Leica's purposes. Then, if you use Lightroom, you can assign your own custom profile based on custom EXIF. I've once done this, teaching LR to assign Leica R lens profiles to Leica R lenses mounted via chipped Leitax adapters on Nikon DSLRs. Your imagination is the only limit.

In summary you could automate the EXIF assignment process, even for legacy lenses. You would need to take control of the 6-bit code assignment definitions yourself. You would have 64 possible combinations. The now defunct Phigment Leica M to Sony E did what I have just described. If only that could be grafted into the Techart Pro adapter.

Yes, I did. It was a golden copy but to be frank, I didn't find much variation with this lens.

I'm not Genji but from my perspective Techart Pro is an M to Sony E-mount adapter so if this new "Techart adapter" that Genji thought about would still be an M to Sony E-mount, I don't see how we can use additional adapters between it and M-mount lenses that are not coded with 6-bit codes to provide those 6-bit codes. (Maybe possible with LTM lenses via LTM to M rings.) On the other hand I don't think this new Techart adapter would be so cheap that you'd like to have one for each lens either.

I'd personally be happy to use a smartphone app to signal to the adapter the right lens information every time I change a lens if it would then record that in EXIF and apply that as focal length etc. if this was made easy and didn't require complicated operations like taking a shot at certain special aperture to set the adapter in the right mode to communicate via Bluetooth etc.

If you would be happy with that approach why not use the lens compensation app for this task?
On the Gen2 bodies the Exif is written in the files and the focal length is also used for the IBIS.

Back in December 2013 I did get the app and I tried it out on my A7r. At least at that time you had to run the app and use its' menus/settings when taking photos instead of the regular menus/settings. That wouldn't be the way I'd like to shoot regularly. Anyway, I think I never tried it on my A7II (didn't know that the app was writing EXIF and using focal length info for IBIS in 2nd gen bodies). Now my main camera is A9 where this app can't be used.

As long as such a process is not automatic, you will forget to do it at some instance and end up with confusion about which lens that was actually used.

The CV 65/2 does have great IQ, but limited macro ability. I can get the same macro ability with two small extension tubes on the Loxia 85, and it is close enough in IQ to the 65 for me. I also prefer shooting macro (and other mild telephoto subjects) with a 85. I'm also convinced the bokeh at macro distances is nicer with the Loxia 85+ tubes. than the CV 65, but that is from online samples I have seen.

It's true, but it wouldn't be that bad to have that happen occasionally. Now when I'm shooting with manual lenses it's mostly with fully manual adapters (no lens or FL info in EXIF), or with TAP (FL in EXIF as long as I remember to set it up correctly, most of the time I do). So another solution like described could be an improvement over those current scenarios if designed/implemented well

Not saying that it would be strictly essential.

Anyway, sorry to OP about writing so many comments on this thread that are rather off-topic from original subject...

I see this exactly the same way.

For me and what is seen around, it's the other way around, Paul, but it's a little more complex. L85 is a startling optic across the board and much less narrow focus than the great CV, which is optimized like most current lenses for nearer distances and near wide open usage. But large landscapes and portraits are strengths of just one of these two, that's the choice, IMO. But it might come down to focal length differences which is easily overlooked. Are you an 85mm or a 65mm person?
