p.17 #1Techart PRO AF adapter now In Stock!
HI all
I got the adapter today and have been spending time with it using the Leica WATE. I first updated the Firmware and went through a number of the posts in this thread to figure out what to do. IF you read sequentially I can see how one gets very confused. I think in the end, the techart has a great product but should provide more information in a pdf. Now after initial confusion, I have a better understanding. However I still have a few questions.

1) Do i set the aperture in camera to F2 (for all lenses) or do I use the max aperture of the lens (f4) or the max aperture of focal length provided in the manual for 18mm----f3.5?

2) I still do not understand the importance of the factory settings. Specifically it states-- set the aperture on the camera body to the corresponding aperture value of the lens data-- so do I set the camera and lens to the specific listed aperture and take one shot?

3) To clarify no matter what I do-- the in camera exif information will not provide the true aperture setting dialed into the lens.

Thanks in advance..

1) f/2 for all

2) settings are optional. If you want to store focal length in EXIF and/or use Steadyshot in auto mode then follow the procedures (set the aperture using the camera dial & fire a frame.)

3) correct, the adapter won't know what aperture that is used, so it won't show up in EXIF.

Look at the center crop picture. I focus on grey building with HSBC logo on top of the building. I think the corner on Techart may look a bit better but the center is really suffering. To my eye, center cropped on techart is softer and if you look to the left of bulding with HSBC logo building, the short building with HSBC name, the lettering is easier to to read with CV adapter, also phone number on billboard further left. The detail of all the trees right in front of the building is also more blurry with Techart. You might have to download the picture to look on your computer though. I am not sure why but picture shown on the forum on my computer is not being displayed at a proper size. Looking at original jpg in photoshop on my computer, the center portion really was significantly different. Pretty much anything from roof on foreground, trees leading up to the building is sharper with CV adapter.
The corner difference is much much less, I agree. May be a tad better on Techart.
The only reason I noticed this was when I was trying to compare 50/2 and Sony 50/1.4za. Using Techart initially, when I look at the picture, I actually thought that 50/1.4 za was so much sharper that I was really surprised. But once I switched to CV adapter, then I could see a lot of difference between Techart and CV adapter output. Focusing with 50/1.4 za on the same HSBC logo building also gives much sharper foreground similarly to using CV adapter than with Techart adapter focusing on the same building at F2 also.

Just got my adapter for the Zeiss Contax 35-70/3.4. Motor drive sounds like all the other lenses so it doesn't appear to be too heavy. Having AF on this lens is going to be fun.

Also, remember to set steadyshot to manual, and set the proper FL for your IBIS, if you use a lens other than the FLs listed in the factory settings for the adapter.

Your exif data will read whatever was last set for the adapter, but you can use LensTagger to update it in LR. And you can also enter the aperture manually, if you like.

And yes, the documentation is horrid, but the adapter seems to work quite well.

Nice!

I've got one "on the way" (he said, waiting impatiently), and am very much looking forward to it.

Also, I picked up a few non-Leicaist branded adapters (various branding) from eBay and Amazon, and they seem to work well.

Just make sure they have that deep, hook-shaped notch on the mount and you should be good to go.

This post is pointless without a pic.

Edit: I could swear there wasn't one. OMG the sharpness of this lens @F4

In all seriousness this adapter is not the easiest in low light but first glance at a lot of wedding images, it was nailing it most of the time but you really have to watch yourself in low light. Its either this or do it yourself. Now down the road my bet this will get better. But Im pretty good but this shoot was not a cake walk either with this combo. you need to stay above 5.6 at least to get the focus

I have a lot more to post in the next couple days but this Tech Art is making my day.

Here are a few tidbits of info.

I have been using it on an A7II with a lot of manual lenses and actually prefer the hands on feel. But it is really more of a AF assist especially after you get over 50-60mm since you have to put the lens into the right focus zone manually.

AF-S is not accurate enough for me, at least with my copy on the A7II so it's best to use AF-C then its pretty accurate.

My copy eats the battery overnight. Lose maybe 10-15% overnight = annoying.
Seems to tax the battery but I have never counted the photos to dead.

There is a particular L-bracket sold on ebay that is barely thick enough to allow normal tripod use.

I have probably 10-12 lenses I use it with, from the Canon FD 17mm F4 up to an Adaptall 80-200mm F2.8 and an Adaptall 60-300mm macro.

Some lenses work better than others.

I wish they made one of these for MFT.

I just discovered something

On AFS you cannot change Priority Set AFS you can not set balanced emphasis but on AFC you can.


You can in AFS only have 2 options instead of 3
AF
Release
Balanced emphasis you cannot use

On AFC

AF
Release
Balanced emphasis you CAN Use
