Hi, I purchased this and like it, I have a question about the 40x objective lense. No matter what I do, I can not get it to focus even after cleaning?

I did not have any problem using the 40 X objective lens. I suggest you call AmScope. They are helpful. Jim

Did you try cleaning the lens. Try a Q-Tip and some alcohol. See it that works.

Check out photography-on-the-net forum - some discussion there. I have used the 10x zoom to check focus, but with the incredible depth of field for this lens, it is seldom an issue.

I didn't ask about their warranty, but when I received mine, the objective lense wouldn't go past 100. I contacted the vendor and told me to send it back (their cost) and they would correct the problem. Due to a misunderstanding with the customer service person they reimbursed the entire cost. I called and complained to the manager who instructed me that if I still wanted one, he would sell it to me at a discounted price directly through them. I received the scope and am very pleased with it. Hope this helps. I did ask the manager about warranty, and there is one, unfortunately, I don't remember the duration; it is directly through the vendor.

I've been using mine for a long time now and never had any focusing issues. One of my favorite lens. I was so pleased with it I also now have the 30mm f1.4

Your sensor might be dirty - this requires professional cleaning. The battery would have nothing to do with it. Your lens might be set to MF (manual focus) on accident too!

What do you mean by it doesn't recognize? If you're talking about the aperture control auto focus etc its normal because its a manual lens everything is controled on the lens. dont forget you have to enable the feature "release without Lens" otherwise you can take pictures :)Hope it helps

Do you have a filter on the lens? If so, try it with no filter. Something might be interfering with lens movement.

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.

I haven't gotten mine yet, but I ordered it. I think I read that the silver ring on the front of the lense is how you adjust the focus...give it a try! If it doesn't work, contact the seller or something.

It just doesnt seem like any of my pictures are focused well and that includes ones taken on a tripod with IS turned off of course. I keep reading and trying everything to no avail. I may contact Olympus and see if something is wrong with the camera. I entered a question about my problems in a forum and the responses were so cruel that I wont ever go back to that forum. There is a review that says the E520 pics can be soft... does that mean out of focus too?

You might want to make sure you have the AF turn on both the camera body and the lense. They are two separate settings.

I have the same problem and mine miss focuses too. I have contacted Nikon, but I'm still waiting for a reply. I'm curious if this lens is a waste of money? Did you guys ever find out what was wrong?

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

My EOS-1Ds Mark III arrived about two weeks ago around the first of Dec. Certainly there are no focus problems on any lens I've tried, and I have 8 or 10. In fact, one can "tweak" the focus for each lens. I've not seen the need for this rather technical step, however, and should I, then I'll do it professionally with correct charts, lighting and so on. It can be redone, though, so any errors can be corrected.
