FotodioX LM-SNE-PRN-MKII Overview

The PRONTO Leica M-Mount Lens to Sony E-Mount Camera Autofocus Adapter from FotodioX allows traditional, manual-focus Leica M-mount lenses to function as autofocus lenses on select Sony E-Mount mirrorless cameras. By utilizing the camera's phase detection autofocus (PDAF) system, this adapter's helical focusing mechanism physically shifts the lens position up to 5mm on the Z axis, enabling autofocus even on manual-focus lenses. It supports both AF-S and AF-C focusing, in addition to face-detect autofocus and 5-axis image stabilization on enabled cameras. An integrated function button allows the user to enter various focus modes as well as setting the focal length and maximum aperture of the lens used on the adapter for optimum compatibility. Also, by utilizing separately available lens adapters with a Leica M-mount, various other lenses may achieve AF with this adapter.

When the lens is set to its close-focus position, the adapter's extension can be used to achieve macro capabilities, or set the lens to the infinity focus position to enable autofocus within its entire focusing range. Performance is optimal with 50mm lenses and wider, telephoto lenses may require coarse lens focusing before using the adapter for fine tuning via autofocus. This adapter is designed to support lenses weighing up to 1.3 lb.

Works with new gen. cameras

By Zeljko
Rated 5 out of 5
Date: 2022-05-01

I have original Techart Gen 1 that worked fine with A73 and A7C. That stopped as I upgraded to A7R4 and A1, it was near useless, only sometimes nailing focus after lots of searching. Techart isn't updating that version or offering new one. This Gen 2 pronto works perfectly with A1, and quite fast, though it seems to be a bit quicker and more sure footed with longer (physical forward, not rotational) throw lenses like Voigtlander Ultron 35 1.7 and 50 1.2, as compared to Leica Summarit 35 2.5, which exhibits miniscule movement back and forth in order to focus. Anyhow, it does work with all my Leica lenses, including Leica 50 2.5. 90 2.5, Minolta Rokkor 4.0 and old Leica Thumbar(?) 90mm 4.0 (from 50s?). I don't have A7r4 anymore, but failures of first gen adapter were the same on both A1 and A7r4, so I assume it would work everywhere. It's quite a speed beast on Ultron 1.7 and A1! Compared to Gen 1 and A7c/A73 Now I wonder if Techart was ever real inventor, and Fotodiox one to copy design, as was popular lore?! Or firmware developer moved the company, or some sort of for pay development between these two companies etc...

A nice update to the M lens to E mount autofocus adapter

By Amos

Date: 2021-04-15

I have 3 of the original Techart Pro M to E adapters but I have found that with they don't work well with the newer Sony A7R4, A9m2 and A1 cameras. They either cause the camera to lockup, are unable to focus or even with a focus lock the image is not sharp. I have not experienced any of the problems with this version of the adapter.

Will this be usable on the new Sony a7 iv? Will it work with Eye AF?
Asked by: Jordan
It works on mainly on Sony bodies that have Phase detection AF.. The A7IV fits the compatibility requirements, but we will have to see once the camera is fully released or FotodioX updates their compatibility list.

Will turning off the camera also turn off the adapter ; or will it keep draining batteries as all other Techart style adapters do ?
Asked by: Markus
Are you 100% sure? Did you test this ? I am asking because with all the previous Techart/Fotodiox adapters you needed to take the battery out after shutting the camera off and then reinsert it again. Or you would end up with a DEAD battery.
