Sharpest Light Limited posted that new video shot on the Commlite Nikon F autofocus adapter:
Commlite Nikon F to Sony E Electronic adapter will be shipped out of the factory in next week. The adapter firmware to be launched will be version 2.0 rather than version 1.0 currently on our hand. Commlite promises that focus performance for the long range lens will be improved. The supporting list will be finalized in this week.

The performance looks awful!!!!
Miles from Chen Steel ‘s adapter! Why They dont Even make him a phone call?
CHEN? What about you? We Need you!
The firmware at this moment still haven’t make adjustment for Tamron lens。We will test it again after firmware update. The priority is original Nikon lenses. The adaptor shipping out next week will be loaded with firmware 2.0。We will test it again ASAP。Please LIKE our facebook page for latest information. Than you!
PLEASE !!! Ask Commlite to support Sigma 800mm f 5.6.
We will put up a poll on facebook later to see which lens should get update first. Thank you!
Oh, an disappointment!
Guess we will have to wait for another generation or two to get acceptable working adaptors.
Won’t be long! Right now we tested with adaptor firmware 1.0. The adaptor shipping out next week will be loaded with firmware 2.0。Commlite is making improvement on long range lenses. We will test it again ASAP。Please LIKE our facebook page for latest information. Than you!
It does seem the A7R II AF performance is not great on long focal length lenses from Canon and Nikon. Is this something to do with the optical geometry of the on-sensor PAF (which may not be as optimal as a dedicated PAF array that isn’t compromised by needing to double as an image sensor), or is it an adaptor issue? Do adapted A-mount lenses of comparable focal length exhibit the same sluggish behaviour (using the non-SLT adapter of course).
I have used SAL70200G and SAL70400G2 on my A7rII with LA-EA3, and it most certainly is not as bad as this. They are slower than native SEL70200G, but SAL70200G is completely usable and SAL70400G2 is very usable with high contrast subjects in decent light. The main problem I have with adapted SSM lenses is aperture closing delay when not shooting wide open. That adds to shutter delay and also AF does not seem to track while the aperture is closing, so it often misses focus by a tiny bit on subjects which move towards or away from camera. Also, time-lapses end up with flicker because the adapted lenses are focused wide open with aperture snapping shut on each shot. I wish there was an option for adapted lenses to keep aperture closed down while focusing, just like the camera does with the native lenses.
Nice to see a third pardy helping out with the testings, and they really should, because it’s the easiest way to open the market for more people.
it looks like it’s not good at all to bother buying it even for a Nikon fen..
Well if you want EXIF data from the lens in your files, it could still be useful but an awfully expensive way to do that.
Admin, it is the Nikon 14-24mm not 12-24mm that is tested. There is no Nikon 12-24 f/2.8G.
In my experience with my A7r2 one has to try different settings for AF field size like S, M or L: IMO he chose a too small setting.
This will be available soon.
How do I preorder one ?
Its amazing that it says “Still doing good” on the 300MM lens. I would hate to see what the video creator would thinks “bad” AF looks like. Looks like it will be a VERY long time(if ever) before we see lenses over 200mm for the A7 series of cameras from Sony as well. Is anyone learning why we don’t see the “pros” using any A7x’s to photograph sporting events?
and people will buy them, then complain and blame it on the cameras rather than the pairing of adapter / lens.
I wondered about keeping my Nikon lenses vs. selling/re-buying A-mount. I think this just sealed the deal to go through the hassle of selling gear. Ugh.
