Having trouble with manual focus. Lens does not move forward without excessive force. What am I doing wrong. Thanks. Ed

You have disengaged the Auto Focus on your camera? The pin motor might still be engaged. Pushing it could do significant damage to the lens and the camera.

Ed. It's really hard for me to ascertain what the problem is from your inquiry. Are you having a hard time moving the focus ring forward and back? The one on my Tokina moves smoothly and locks into place with a nice snap. You jut pull the ring toward you when you want manual focus and push away from the camera for auto focus.

The push/pull focus barrel on the Tokina 100mm f2.8 macro takes a bit of effort to engage and disengage. It has a positive click when shifted in and out of manual focus. If yours takes an extreme amount of effort than something is obviously amiss with the focus clutch on your lens. I would not force it in and out. If it requires too much brute force it would be advisable to have it serviced. It is unusual for the focus clutch to develop a problem but having said that anything made by man isn't perfect. Tokina lenses are very robust as I use the 11-16mm and the 100mm macro and have never had a problem (touch wood) and the 100mm macro gets lots of use of the focus clutch.

The lens itself must have manual aperture. I returned this.model for a.more.expensive one with five settings.

I have not been happy with the auto focus. I have used this lens with both a cannon T3 and a cannon 70D. The problem is it will no come into focus. I have contacted sigma asking if there is anything that can be done about this. I have not yet gotten a reply.

Yes, you can focus manually. Manual focus is on the lens. Just circulate the lens, and you will manual focus the camera.

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.

Its a macro lens. Try getting as close as posible , you almost have to be touching the object with the lens for it to focus

Peterson:I have the same lens and want to buy a D40 - have you figured out yet if it works. From everything I read it should work on manual focus only ?

Exactly, I have the same experience. Once the lens focusing is a bit stiffer then the follow focus jumps up and down.The only solution is to replace this follow focus with the one without the quick release, as I did and I am quite satisfied now:Fotga upgrade DP500IIS dampen follow focus with A/B hard stop for DSLR CameraFotga upgrade DP500IIS dampen follow focus with A/B hard stop for DSLR Camera

It's a great lens if you can get it to work without any issues. Please make sure that the lens focuses currently.

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 likely have to use the manual focus ring on the lens itself. This adaptor doesn't allow for auto-focus capability.

I have the gf3 and mine will say that if I have it on autofocus. Put the focus in manual and click away after getting the focus, shutter, iso etc how you want for your photo. Fun lil lens. Ive gotten some great shots with this.

You've probably figured this out by now, but in case anyone is browsing this forum later on and still wants the answer, I thought I'd post. I use old manual focus Nikon lenses on this camera all the time. There is no auto focus, but they work perfectly fine in manual mode. I have a 10 dollar wireless remote I bought off of Amazon that works great for long shutter exposures.

Yes I have the same issue. There is nothing wrong with the lens. It is a third party lens and is totally manual. Flip your camera to manual mode and adjust your settings. The camera will fire is this mode.

Anything you do to inhibit lens placement will cause zoom error. If you aren't doing anything to inhibit lens movement, maybe there's a bit of schmutz?Otherwise, call olympus and please post reply.Peter

Sorry I just saw the incoming email. Let me understand first. Are you saying that there is no way to do an "autof" on your camera with the lens? Try half way press the shutter see if the focus can be achieved.

The only thing I can think to try is turn off your auto focus to see if that helps. Good luck
