Re: I can do that

One would assume you mean $55 to cut a K3 that we sent you? Do you have access to K3 screens, and what would the total cost be if you supplied the K3 screen and cut it for the 20D? Would you agree that a cut K3 is better than your original Haoda 20D screen?

Do you have another screen that you think is better than a cut K3 for the 20D? Why is it better and what is its cost?

Thank you.

Re: I can do that

This issue have been discussed on my yahoo group.
I do not think it is better. It depends on what you need.

Re: Installed the enhanced screen in 20D

I used lense cleaning solution on it the last time and used small burst of air. Not sure if this way is best, but after several bad tries this last one worked.

Thanks! As soon as I get enough nerve to take it apart again, I'll give that a try

Please be very careful about using lens cleaning solutions on the focusing screen, as some of them can damage the screen. If you need to use a liquid cleaner to loosen stuck dust particles, the best thing to do is rinse it in clear water and then blow it dry with your air puffer. Blow drying is important to prevent water spotting. In extreme cases, you can use mild dishwashing liquid in the water and a very very soft brush, followed by a thorough rinse and a blow dry. But I do not recommend commercial cleaning solutions, since many of them can damage the screen. If you need more detailed instructions, feel free to contact me.

Racheal,

Now you have me losing sleep!! How am I to know if I have damaged the screen?? I am not noticing any scratches, but would the damage be something I would notice? There goes my peaceful rest tonight.

Relax Charles - if it looks ok to you then you haven't damaged it. Some commercial lens cleaning solutions will actually soften the plastic the screen is made of. If this had occurred, you would notice smears on the surface which would be readily visible in the viewfinder. If it still looks good, then breath easy, for all is well

Getting the dust out

I started by blowing out the mirror box, cleaning it with a charged brush and the discharging it with a Zerostat gun. I blew off and brushed the replacement screen with a charged brush. The same with the AF point screen.

What other focussing screens are conceivable?

So the Nikon K3 is (among?) the brightest, and used by Katz Eye.
So the K2 is nice also

The Contax FU-... works, but is significantly darker.

The Nikon F3-screens results in backfocus unless lowered into the camera, so the edge has to be worked to make them fit.

No need, you say?

But then, Nikon has very interesting focussing screens for the F-series, some of which still seem to be available.

For instance the H-screens (available in four types) has no split screen, but has microprisms allover! No need to focus in the center, you can focus anywhere, but the non focussed image might look strange. What is it intended for? According to Nikon it was intended for sports photography, i.e. fast focussing, no time to reposition the camera, etc. I would really like to try such a screen, as I take a lot of pictures in near darkness with wide apertures, social dancing. While my Contax screen is quite helpful, both framing and focussing remains difficult.

But then, the type H screens are not available for the Fm bodies, but for the F bodies only (with the above mentioned back focus problem)?

What other types of screens would be interesting?
