    Best lens I own

    I have 3 Zeiss lenses for the NEX APS-C  (12 2.8 touit, 24 1.8 and 16-70 F4) and now the 35 FE2.8 and the FE5 1.8 for my A7r. Others than that I used several older manual Zeiss lenses on the NEX-7 and experimented with some on the A7r as well. To make it short: This lens is nothing short of amazing! It's the best Zeiss lens I have used so far! All the pictures I took with this and the A7r I made wide open have such a high level of crispness, detail, colour and contrast, I don't know how a ...

FE 55mm diaphragm noise when focusing.

I got my Fe 55mm yesterday, I have tested it on my old nex5 (a7r is coming). When I focus (autofocus), the diaphragm opens and closes more or less and make a relative loud noise I have never heard  with other lenses on the nex5 or with an other lens. Is it normal or should I return it for an exchange ?

like my sel sounds like you's happening, when the aperture is very small, like F8 - F11....during AF, lens goes to F1.8 to collect more light, during this change, you hear it..however, if you're at F2.0-F2.8, which is close to F1.8, you cant hear it...try it and let me know :) Continue Reading

yes it is like you described, when focusing in A mode with aperture set to f2 there is no noise but at f11 the noise gets loud and annoying. I wonder that this happens with a so expensive lens. Continue Reading

Are the new Sony full frame FE lenses compatible with existing NEX cameras?

I'm in the market for a premium lens for my NEX-6, and so am interested in whether I should be buying FE lenses instead now, so that if I ever decide to upgrade to full frame Sony mirrorless in the future (which I think I probably would like to do), I wouldn't have to buy (as many) new lenses again.

Yes, FE E-Mount lenses are backwards-compatible with NEX E-Mount cameras. Continue Reading

Question, if full frame lenses work the same on crop APS-C sensors, then why do companies like Nikon offer different variants of lenses? i.e. FX and DX lenses, because they're pretty much the same physical size. Why not just make everything FX? Continue Reading
