    I finally got this lens today, I ordered it but was offshore so just back.

    I had read several articles where it was used with the A7R and A7 and they found it was fine as a full frame lens between about 12-16mm but on the A7Rii it really only works from about 14-16mm :-( I bought it as a wide zoom for the A6000 and was hoping it would be OK on the A7Rii in full frame mode and could replace the CV12 but alas not.

    It's a nice lens though, well built and finished, not too big or heavy.

    I was hoping to get out and gets some shots with it but thunderstorms and rain here today.

    Silly me, ignore that first post, I had the lens hood on, the hood is fine for cropped mode but needs to be removed for full frame, now I can get 11-17mm.
    I need to do more testing outdoors and checke the corner sharpness etc but looks like it will be OK.

    Interested to see some shots and hear your thoughts on its performance on the FF ;)

    I managed to get out this afternoon after the rain finally stopped. The corner blurring is the biggest problem, it depends on the shot and what distance the stuff in the corners is. I need to play about with it more, I think the focus point is crucial to minimise the corner blur so need to experiment with different focus. It's so nearly an excellent FF lens that gives coverage between 11-17mm but depending on the shot the edges let it down.
    I've been comparing it to the CV12, the CV12 MK2 is a really good lens, the corner distortion and blur is minimal, the 10-18 has a monumental task to match it.
    I'll post shots later.
    It's a cracking lens on the A6000 though when used as its meant to be used on a cropped sensor camera.

    That was my experience as well. The 10-18 was the only lens I kept when I replaced my NEX-6 with the A7. But the smearing in the corners in even the best of circumstances made me eventually give up on it. There's only so much "good enough" compromising I'm willing to do.

    Here's 6 sample photos using the 10-18 on my A7Rii, all the shots @12mm f16 with the camera in full frame mode (not APS-C), all PPed in LR and lens corrections applied (although for the lens used on a crop sensor).
    Some of them are quite acceptable but others are let down by corner smearing unfortunately.

    Thanks for sharing these!
    Yeah, there's quite a lot smearing and some softness at the corners but I think that's also cause this lens is so wide. It would be nice if this lens was as good on FF as it is on apsc, as it very affordable :(
    Would be nice to see some other FL examples as well (15mm) but no pressure :D

    From the results of my testing I'm keeping the CV12, it is a really good lens with excellent corner sharpness etc, the 10-18 can't compete with it at 12mm full frame.
    I'll keep the 10-18, it's an excellent lens for APS-C but I don't think it will get a lot of use as a full frame lens.

    On APS-C, if you could only have the CV12 (or CV15) or the 10-18, which would you keep? I like my 10-18 well enough, but have considered selling it to fund one of those.

    The 10-18, it covers the equiv focal range from 15-27mm, the 12mm is equiv 18mm and the 15 equiv 22.5, neither offer particularly wide angles if used as APS-C lenses.
