Sony A7 users...

ChrisWilsonEos · 12 Mar 2015

Hello, I'm currently using a canon 60d which as you may know uses ef-s lens', my most used being the 10-18mm.

Now it looks like a Sony a7 may be coming my way with a kit lens, I will eventually purchace the 17-?? Wide angle FE lens but I'm just not ready to spend £1000+ just quite yet.

So what I really want to know is how my efs 10-18 would work on the a7 using a good quality lens adapter in the meantime... What would be the actual focal length? Would I encounter much vignetting? Etc..

Thanks in advance for your help.

Even if you were to get a full image circle, you could only use the lens wide open which would be somewhat limiting.

Not quite correct, he can use an adapter with contacts (metabones) to change the aperture on the body.

The lens will have vignetting, wether the crop mode on the A7 will work with an EFS lens Im not sure, it works with native though.

Whoops, forgot about that! £280.00 for the adapter mind.

Nope, there are copies available on Ebay that are much cheaper.

I saw a video sample of the 10-18 on the a7 and it had very bad aliasing, is that something that could be a problem for stills? As I understand it, aliasing is jagged diagonal lines right?

that could of been theencoding, and should be no issue for stills or 4k, as full sensor readout

Crikey you are right, can be had for under £70. Watched a video review though and AF was like using liveview on a DSLR. Certainly makes the lenses fully usable for landscapes and portraits I guess.
