Focus screen

Was out last night doing some night shooting and had to make a run for it in the rain, so earlier i took the lens off the camera and the focus screen was sitting there, so i popped it back into place and took some photos and all works fine, but there was a lot of debris on the screen so i took it out and cleaned it with a sensor swab and some cleaning fluid, but the debris / marks are now a lot worse, so is the screen done or is there a way to clean the screen?

Well... I'm sure someone will get excited, but when I changed my focus screen to the older split screen style, the screen is a piece of plastic...

Having said that... I've found the best plastic lens cleaner has been some warm water, and a few drops of Dawn dish washing soap... rinsed in cold running water... and just barely pat dry with a clean paper towel...

I'm not sure which camera you have, but new focus screens are about $30 on eBay...


BTW... There are a brazzillion YouTube videos showing how to properly change your focus screen... I'd view those to understand why/how yours became dislodged to begin with...

Thanks, i can only assume it came dislodged when i was running with it last night, might give the washing soap a try later.

Years ago, back in the film days... My Canon A1 had some junk on the focus screen. I wiped it off with a cotton swab. I don't remember if I wet the swab first, but it was just a gentle few passes, not like I applied any heavy cleaning force. That left me with bad scratches. The screen was plastic and highly polished in the split prism area and a gentle wipe with the swab ruined it. So be careful, but they are not too pricey and now you know how to do it and how delicate they are.:)

Should you ever find you may focus manually, and there are certainly many times when focusing manually is preferable to autofocus (like macro), I suggest look at an aftermarket focusing screen. I have one on my D700 which is ground glass with a microprism center, it is dead on. I ordered a split image center with a microprism collar for my D7100 but it is still in transit. I have found that focusingscreen.com has excellent screens. Katzeye also offers them but I find them overpriced and their selection is not nearly as extensive. The split image/microprism screen I ordered for the D7100 is a Nikon K3 screen. The one on my D700 is a modified Canon Ec screen. If required, the screens will come with a brass shim to be placed between the screen and pentaprism to ensure that the focus is correct.

Whats the difference K3 from Nikon compared to the K3 from focusingscreen.com?

The Nikon full frames; are they comes in different focusing screen sizes?

I thought it is standardized. Just like your lens mount.
