Question about Casio Exilim EX-Z750 Digital Camera

Out of focus - "shortsighted"

First camera - slammed it in a car door, kept it for parts. Bought another one, because I liked it. Dropped it with the lens open, then all images were very out of focus. Decided to try to fix it using the old parts. Changed the lens assembly - just a matter of careful disassembly and reassembly, little screws and tiny ribbon cables which you unlock, pull out, put back, lock. Got a camera that was much better - usable, but still somewhat "shortsighted". When focusing over about 2 meters away, images came out with a slight blur, small enough to be invisible unless zoomed in. Investigated to see if I could recalibrate the firmware - no easy fix. So I thought about it. A shortsighted person has an elongated eye - retina too far back. I tried tightening the 3 screws on the sensor at the back of the lens assembly - no. So I put a piece of paper, folded to about 1.5mm thick, in between the lens assembly and the LCD. Much better - now I can take up to 3 MP photos without noticing the blurry focus. 7 megapixels is still blurry beyond 2 meters. (I also thought about glasses, but that would have looked really silly.) ... just sharing my experience. The problem is 90% solved as far as I'm concerned, the camera is still very useful for video where the resolution doesn't matter so much, and short range shots of documents, the two things I used it for mainly anyway. But if you have some advice, I'd love to hear it.

Re: out of focus - "shortsighted"

You seem to be on the right trach I would have thugh- just packing out the lens ass until it is the right focal length Is the focal length mentioned on the mount anyplace? Then you could measure exactly what the rear element distance should be from the CCD

I have a Casio Exilim EX-Z33 and i dropped it a while ago and it continued to work (kind of, the images were a bit blurry). i took a picture five minutes ago and then turned it off. the lens went in but...

Sounds like the focus motor came loose - you need to take it apart and repair the gear that drives the lens assembly for focusing. The noise you're hearing is the motor trying to focus but since the lens cannot focus it continues to run and signals an error.

Camera dropped into water: HD movies are ok, but pictures are bed

First of all, no, you can't open the lens to clean it...the tolerances between the lens elements is so tiny you would never get them right. Second, salt water is "ate" your circuits. Even if Canon fixes it, it will still give you trouble in the future...usually right after their 30-day repair warranty is up. You need a new camera and possibly a new friend.

Focus problem olympus fe 34o

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

unfortunatley when these cameras are dropped they can cause the lense to become unaligned and create a focus error if twissting dosent help it would need to be sent away for repair to have the lenses realligned but it wont be covered by warrenty
