Techart Pro LM-EA7 M to FE autofocus adapter owners thread

[Suras]

Hi all,

I just received my adapter from techart (for you who are still waiting, i was no 603 in que).

My initial impressions is pretty good. Only tested it indoors in quite dim conditions and it perform pretty good.

As stated earlier, it also acts as a close-focus adapter which gives pretty crazy effects and bokeh with for example the CY 85/1.4.

The Zeiss 85 is a relatively heavy lens, and it works no problem. It has a pretty long focus throw and the adapter doesnt seem to cover the whole focus range when set to infinity, but its easily fixed by simply using it combined with coarse manual focus. the focus appears accurate to me.

 

Its also clear, that while some generic adapters works well with the adapter others wont. 

Id imagine Im not going to be the only one with theese problems, So i suggest we just list experience here.

You CAN buy Techarts own special adapters which are guaranteed to work.

 

Let me start:

Fotodiox C/Y to M  WORKS.        I have so far only tested my CY 85/1.4

Fotodiox FD to M   do not fit 

 

Next up ill try my canon ltm 50/1.5

 

Cheers

Suras,

 I would be curious to get an update now that you've had the adapter for a week.

I am still sitting on the fence on this one, since I'm actually not unhappy with my hit rate with MF. What other CY lenses do you use? I have:

Distagon 2,8 / 28   

Planar 1,7 / 50    

Planar 1,4 / 85    

Tele Tessar 3,5 / 200   

Vario-Sonnar 4.0 / 80-200

Varion-Sonnar 3.3-4.0 / 28-85 

 

Cheers

Hi Marc,

Sorry for not replying.

I only got the 85 1.4 (love your collection...)

 

It handles the weight well i think, and it does focus very accurately, and relatively fast. 

I think its also in credit of the very good contrast of the lens (as are the rest of the CY...)

I tried it on my canon LTM 50/1.5 and it works well too but my feeling is that it needs more light for the same focus speed compared to the 85.

This pretty much mirrors my experience focusing theese lenses manually. If they have the super crisp characteristics like the CY85 its a very clear transition for the adapter to optimize against (im speculating).

Also, for lenses with long focus distance you will have to assist it manually to be in the right range as the 4?mm the adapter is able to move isnt enought to cover the whole focusrange for longer lenses.

To me its not a problem at all as im used to manually focus theese lenses anyway.

The whole combo (Techart, Fotodiox M to CY) isnt noticably heavier to me than the quite chunky FE to CY adapters i used previously (metabones), but on the other hand, the package isnt particularly slim anyway with the big honking 85 at the end...

Thanks - Looking forward to some pics and more real life experience

All the best
