How to adjust the focus of Olympus lenses?The E-30 has a Focus Adjust feature but how do you determine if a lens back or front focuses? Then how do you properly use the Focus adjust feature?

Let me start with a guess. There is a diopter adjuster just behind the viewfinder. If it is adjusted way off from the correction you need, everything will look no better than out of focus though your photos may look fine. Google how to adjust the diopter setting on the D3200 and see if that won't take care of the problem.

Here is one of the secrets: your camera has so many adjustments that if someone else picks up your camera, they may change a setting leaving you wondering what happened and why. Be cautious.

If that guess is not the cause, let us continue. Are you saying that when you switch the lens setting from A to M, it still will not manually focus? Some of the lenses are mostly made for autofocussing, so the focus ring that you have to turn for manual focus could be narrow and out at the very front of the lens. If you cannot manually focus, something may have happened to the inner works of your lens. Try another Nikon lens to see if it will autofocus. If it does, your lens requires servicing or replacing.

Good luck. Hope you get back to shooting soon.

That's the backfocus problem. Take your camera to a Sony service.
If the lenses are ok, they will do an adjustment. If the lenses are defective, they will
replace the lenses, but that costs much.

If you take it to pieces, you will end up with a (hopefully complete) kit of parts which you will have to pay a repairer to re-assemble for you. Your choice.

since you have then lens out, get a wide blade flathead and insert it in the smallest part if **** that it will fit into behind the focus ring and turn the blade like you are trying to widen the **** all the way around until it pops out into it's normal position. Getting the entire lens back in properly is a bit tricky since the threads are easily stripped. First screw it all the way back on and then check the focus on the screen. You want to see a crisp image in 3 if not 4 of the outer corners of the screen. It is best to use something with text that fills the whole screen so you can see the 4 corners as you adjust the focus. If the focus is good in the corners, leave it alone. If not,hold the back of the projector in one hand and forcefully push the lens into where you screwed it on and see if it pops into place. It really is trial and error. Once you have a clear picture it is a good idea to remove the top cover and glue all around the base of the tube where it screws on so it doesn't come loose again.

When you say a shift focus issue, what exactly is the issue? Will it not focus to infinity? Is it never in focus, no matter what? Is it an AF lense that is searching for focus?

Either way, it really requires an experienced tech in all but the last case. There are cases where AF simply doesn't work well. You can have it checked, but its likely nothing.

The other issues, it's likely either a misaligned element, an element that's come uncemented, etc. You may be able to look through the lense and see if you can see any separation in the elements, though sometimes it's not terribly evident.

Unfortunately, often unless it's a simple issue lenses are more expensive to open up and do major repairs to than they are to replace. If you'd really like it looked at, contact Nikon for a service center, a local reputable shop, or contact KEH Camera in Atlanta, GA.

Not focusing at every distance - close to far ?? That seems like a lens problem to me and how the lens is focused, once its fully extended, varies between camera brands. .
Have you dropped this camera or knocked the lens when it has been open ?? Or have you dropped it at the beach and got sand or grit in the lens ??. If it is a lens problem it will have to go back to the service agent for repairs - ther is nothing you can adjust inside unless you are a camera technician

If the AF is set to release then the camera will release the shutter before focus is attained. Set it to focus only and see if it improves. Don't leave it like that, you will miss pictures.
Shoot some pictures with the center AF point only in single release and see if the focus is consistently landing in front of or behind what you wanted in focus. A penny on the sidewalk shot at a 45 degree angle in aperture priority with the lowest A number possible is a good quick one. For super fine tuning with a f2.8 or faster use a fuzzy plant branch like a tomato plant. If whats in focus is always in front of or behind what you focused on then you need too adjust the focus(back focus) in AF fine tune until it lands where it should. It's an annoying process that involves shooting, adjusting, shoot again, see if its better or worse, adjust, shoot and repeat. On zoom lenses use the middle on the zoom range because it will usually go from back to front focusing on the long and short end. The camera remembers each lens and the process must be repeated for each lens.
Last thing I can think of is the one that no one wants to hear and is most likely the problem, Camera Handling. People have a tendency to get sloppy after getting use to a camera. I have noticed that the VR lenses don't like people that stab the shutter button. It wants to remove fine vibration and a harsh stab makes it jump back to center and if the shutter opens at the same time it will put fine motion blur in the picture and looks out of focus.

will watch this post have same problem with focus especialiy indoor flash shots. a lot out of focus

Yes, this is normal. Some zoom-lenses adjust the focus when zooming, to always keep the subject in focus. Those tends to be the more expensive lenses.
So you don't have to worry, nothing is wrong with your lens.

Just returned from trip to Cuba..most photos taken outside and few inside...all photos were exc. or good except the ones I used with the telephoto feature. Had I left it on the W feature,these photos would have been ok...also make sure the focus ring lens adj. is not on the macro imaging feature..found that focus ring lens setting sometimes moved when I put the camera into its case
Pancho-poppa..
