Anyone tried the Sigma 35mm f1.4 Art on the K-3II?

schnitzer79 · 05-13-2016, 04:14 AM

Ive been wanting for some time to replace most of my cheap primes with a quality prime lens and was looking at some of the Ltds but ended up buying the Sigma 35mm f1.4 since i found a great deal on a new one. hopefully i made the right move since its not a cheap lens by any means. Anyone tried it on the K-3II?

I will very soon and will share some images asap. It wasn't quite a toss up with the FA31mm, coz I didn't have the readies. I'm hoping the extra bulk and weight won't get on my nerves.

Fan-tastic lens on the K-30 that I'll be using on the K-1.

I have it on the K-3. It's a very sharp lens, and optically great.

My only gripes are:
(a) it's large, heavy and not at all discreet;
(b) the AF has been very inconsistent on my K-3. As in 'shoot the exact same target 5 times, 2 shots will miss focus'. It's a nuisance.

My most used lens on K3!

Unfortunately, Sigma recommend against using it on the K1.

I've already put it on and taken test shots without problem, Paul. ☺

The lens might scratch the camera a little due to the slightly bigger mount. I think Sigma is dressing the issue and will soon give some sort of repairs, modification kit. There is PF front page post about this and also a big thread, since Sigma issued a warning regarding using certain lenses on the new K-1.
They might cause a scratch, and they might slightly push the mount. Just so you know, do as you wish

I have it on second K-3 and it is amazing. Do not have any issues with missfocusing. Excellent sharpness.

I don't think I would take the risk. It's not so much the mark on the body; it's the stress placed on the mount by having the lens wedged against the body. I'll wait to see the "fix" that Sigma is promising.

Here is my very first shot. Wide open and hand held. My desk isn't the most interesting place but I think the shot is worth a share. The blue things are file boxes, not fringing.

Yep, it's chunky but about the same as my Sigma 70mm macro, which I frequently use as a walk around lens. The FA 43mm will probably stay my go to lens when I'm doing serious walking and want to go as light as possible. Otherwise I can see this lens getting pretty frequent use, particularly when I want quiet AF.

interesting shot.
mine came as well and I agree, it is quite chunky but it feels great on the K-3II with the grip. didnt get a chance to test it properly but from a few quick shots, the AF is ever so silent and fast and was surprised by the sharpness even at f1.4. From f4 onwards, I think its my sharpest lens to date. Still want to check if it misses focus occasionally as reported by a few. Will post a few pics when I get the chance.

OK, I have only gone from my messy desk to my messy coffee table but I cleared the kittens off it and plonked a souvenir donkey (I think from Greece) on it.

Here's the K3ii, Sigma 35mm F1.4 combo with a pixel shift shot from around about minimum focus distance.
