hi everyone I am looking for a 'normal prime' for my SLT and was wondering if anyone has done a bit more research in the mid-low cost range. I bought a 35mm sony (SAL35F18.AE) and I'm not very happy with what it does. I was wondering if the 30mm sigma 1.4 was any better or anything else out there is good. thanks for your views

Hi everybody, I got a second hand Sigma 30mm f1.4 which is in good shape except one minor problem: it squeaks like a seal when focusing and hunts quite a bit because the friction of the focussing mechanism causes stick-slip effects. I can feel the friction is higher that it should be when I focus manually. In good light the focusing work better simply because the motor works harder. Still focus is a bit of hit and miss. Now I had a similar problem with a sigma 50-500mm of which the af motor...

I am a new owner of a Sigma 30mm f/1.4 EX DC lens and I am trying to figure out its performance right now. I am aware that a lot of people who accuse their Sigmas of having front/back-focusing problems are actually witnessing a camera body calibration problem in phase detection autofocusing and only noticed it with the Sigma because its shallow DOF at f/1.4 exposes camera calibration issues much more than standard aperture lenses do. I decided to test my new lens on my Rebel t4i and I’m a...

I have a crop sensor 4ti and looking at Sigma's 30mm 1.4 The 30mm F1.4 EX DC HSM has been out for years and seems well loved. They just announced an update to this 30mm F1.4 DC HSM. I think the EX means it will work on crop sensor or FF and I like that flexibility though I have no near term goals of going FF. My question is if this is worth the wait, anyone have any sense for this. The price has dropped on the existing 30mm F1.4 EX DC HSM on Adorama and thats a good discount...unless the...
