I'm having trouble focusing with the lens - I've read online that the lens needs calibration when first opened. How do I calibrate the emount version?

I have a nex-6. It's manual focus. I've never calibrated it. You can do this for distortion correction but I just use Lightroom to lessen the distortion.

It sounds like you have a bad copy, i never had to calibrate mine and it is very sharp from pretty much wide open.

I have this lens and like the wide-angle nice pictures it gives, but it does not have auto-focusing, you should focus manually. and I never heard about calibration (at least I never performed it) - just switched to M (manual) focusing when using this lens.

Twist the lens. It may be that it is indeed too low to get a good focus. If you twist the lens on mine, it comes into focus.

When we first got ours we had the same problem with clarity and had searched all through the menu options with the blurry image trying to find it. The plastic part around the lens is what you use to focus the image. The first time it felt like that wouldn't move but if you keep at it gently it will work and then you won't have any problems moving forward. Once you fix the clarity you can read the menu better to adjust the image size. Good luck.

I as well have a focus problem, I have to bump the zoom a bit when I first start the camera. Not aware of any solutions and am looking for a warranty fix.

Thanks here too. Pulled on the lens. Worked first time, then got another error next on/off. Tried a few more times. So far so good now.

You have to be able to turn the lens incasement in order to adjust focus.You also might need to clean the lens with soft lint free cloth to remove any fingerprints that may be on the lens. If you haven't got too far on the install, you maybe able to adjust then reinstall. I hope this helps.

This superb lens is slow to focus on most four thirds cameras. On the E-M5 focus is accurate, but slow. On the E-M1 it focusses much faster and accuracy is high. My new EM1 is superb, by the way.

Wow, that's a lot of information to digest! I can tell you really enjoy photography though-thanks for the help! I must have read your latest post like five times!Since I'm still I beginner, I have no idea how to operate the camera in A or M mode so I guess I'll leave the purchase of a prime lens for later on.~ Dan

I second guessed myself as well in the beginning. The lens has a pretty long manual throw. i.e. it takes some big turns to get things into focus manually. Keep trying and it should eventually get things into focus.

Has anyone else found it impossible to get the fisheye to focus? It's blurry as heck.

Basically, when you point the camera to a distant target (like a cloud, stars or the horizon) and you can focus on it successfully. Keep in mind that there are lenses with distance rings that can 'focus' before or past infinity. This doesn't necessarily mean the lens is not calibrated, in some lenses this is to allow for thermal tolerances. In case of adapters, if you have a lens that can focus to infinity just fine in a camera; but can't in another once is attached to an adapter, then the adapter itself might be defective. While rare, it doesn't take much of an error on flange distance to cause focusing errors in that case.

i was confused the first time i used it. you focus with the lens attached. but i still had to get in really close to the subject in order for the camera to autofocus properly

Hello Martin, Go to your menu and navigate to the number one page. You'll see "Release w/o Lens", change that to enable and you're set! Hope that helps!

Hi. I purchased the same lens 2 days ago and yes, I am a novice using a D300. I have the same 'err' reading but when i switch and locked to f/22 i realised that the camera body electronically controls the aperture setting - which you can obviously set in 'A' mode. I assumed that the manual a f adjustment ring on the lens then was only for cameras that do no have electronically controlled A settings via the body.

Yes! You screw it off completely! It shows up blurry if you're trying to take normal pictures, but when you angle the camera close to something, its supposed to focus and look zoomed in! Keep trying, or look up info about macro lenses!

My Sigma 1.4 lens isn't focusing properly. Purchased it Oct.9th. Won't focus past 6 feet. I have to send it to Markam Ontario for repairs. And it will cost me for repairs. No warranty?????

Hi personally it did not work for me. The camera becomes set back so far as a result of the mounting that focussing is a problem. For me other than macro work it was not suitable and certainly not as all round useful as I understood it to be. I returned mine for a refund
