M2 vs SGpro
 

Assumed that they are almost identic, and assumed that i will only use 1 lenses brand, are there some differencies in quality? Some grain visibility difference? Some vignetting difference? Some focus difference?

If you are looking for easier setup and a very nice film bokeh, the SGpro is a good choice. The M2 has been around for longer, though.

It could just be me, but all the test shots I've seen with the SGpro have far superseded the M2, in lightloss, bokeh and sharpness. Darn fine adapter if you ask me.

I can't speak for the M2 -- because it's just too expensive to buy two adapters to compare -- but in regards to the SGPro, the customer service is superb. And the SGPro is definitely incredibly easy to set up. I'm pretty much an idiot when it comes to adapters, but I've gotten nice pics from it, even using cheap lenses. I have the early model of the SGPro and it's pretty nice -- but the new version is supposed to be even better.

Honestly, you probably won't be disappointed with either adapter; but when I was debating adapters, the main reason I went with the SGPro over the M2 was a lower price, better looking footage (in my opinion), turn-around time (when I was shopping, the M2 had an incredibly long backorder list), and quick answers to queries.

I only tried the M2, wich had a good image, but with wide angle lenses i found it difficult to have the image focused at infinity. Is it the same with the SGpro?

Hi,

I have not had a problem with wide lenses on the SGpro. The M2 needs the user to set the GG FFL in a rather hit and miss fashion, this is probably why you saw the infinity was off with your wide lenses.

And how does the Letus35 FE compare with them?
