Question about Cameras

2 Answers

I have a Mitsubishi SL2U video projector, which has two lenses. The outer lens is the focus lens, and the inner lens is the zoom lens. It appears that the inner lens has dust and debris on it. How do I remove the focus lens so that I can clean the zoom lens?

    Iwould just like to have a second opinion,thank you.

    Yes it was. It is such an expensive unit to replace, that I think I'll take it to a professional to have it cleaned.

If the focus lens is meant to be taken off from the front, it can be unscrewed, howevery I believe you will have to take another approach.

I tried to take one of these apart one time, and all I could figure out was that I had to take the whole lens piece off, and get to the lenses from the rear of the assembly, so to speak.

Here is the manual:

Wish I had a diagram, but hope this will help.

    That's probably wise. They have special tools to remove lens holding rings, etc.

read this article and keep in mind that the interior lens is not having any contact with any external source that can dust it ...so it do not need any cleaning ...If yo will read this article will see that any time you clean the lens you practically damage them ...so do not be to enthusiast about it ..if it appears to be anything on it ..is probably a optical illusion cause it is a encapsulated enclosure ..

Cannot auto focus


It sounds like the circuit board flex has gone bad, It folds back and forth when you zoom the lens, And needs to be replaced by a repair shop and readjusted. Tony

Removal of Lens housing


you can't get the front off without taking the top and back off. first, unscrew the 4 brass screws and 4 silver screws from the bottom and the 2 or 3 silver screws from the back. there are 3 clips that you can see through the vents at the top of the rear panel. use a small flathead screwdriver to unclip them and pull the back off. now unplug the plugs on both sides in the back. as you pull the pot up from the rear, pull out the bottom of the front panel and it'll come out as one piece. now you can give it all a good cleaning. use canned air. it's dry and there are no particles in it. when you replace the parts, detatch the front from the top using a pair of needle-nose pliers and unclip the front. put the top on first, plug in the plugs, then put on the front and back, and replace the screws.

I just found my husbands old Minolta maxxum 5 AF Zoom lens camera. I don't know how to zoom in. I am trying to take close ups of my infant and it appears that I can only zoom in on objects 4 feet away....


It's not the fault of the camera itself, it's a lens issue. Zoom lenses can only get so close before the min focus is obtained. Unless you have a macro lens (not suited for portraits, which can focus down to mere inches. Most zooms aren't really designed for close focusing though there are higher end lenses that can be less than 1.5 feet.

Hope this helps!

Blur


Well, that's a general statement. If you are looking to have the image look like a HDTV then you have the wrong impression of the projector's capabilities. At 800x600 resolution you will get a "good" but not great image especially if compared to a tube tv or plasma/lcd. If the graphics are sharp when you press the menu key then you probably do not have an issue. If, however, even the graphics are blurry, then you have to manually adjust the Grey outer focus ring on the lens. The inner ring will adjust the zoom. Hope this helps.

Hi
I had same thing. I took camera to bits and still didn't work. Then one day just before throwing it in the bin with batteries in and lens extended, I grabbed the outer ring (bigger part of lens near the body) and pulled it out a little further. I think there was a slight click then the red light turned green and everything was back to normal. Maybe I was lucky,but its worth a try because it definitely worked for me. Cheers John
