That seems to be the case.
You should do a test as I suggested, shooting a uniform surface like a block wall, so that youo can really see the impact of the screen.
Agreed. I could see that with the spot meter mode. But happening in the matrix mode still baffles me. I don't have the image to post but I could say that the overexposed image you see here is the same with matrix mode too.
I think you are right that the slower max aperture of the kit is playing a role. As I mentioned above, I had an odd experience similar to this with the DA 15 mm which is f/4. I need to try it out with my 18-55 kit lens. I don't think I have used it since getting the Katz eye screen. All my other k mount lenses are faster.
Lowell: what am I looking for when I shoot say a block wall? Will a brick wall do the same?
Originally posted by Ash If your above attempt was spot metered on the black gate, then the result is expected.
Spot meter a dark subject, the rest of the scene appears overexposed; spot meter a bright subject, the subject itself is exposed OK and the rest of the scene underexposed (if comparatively less bright than the subject).
Just stick to matrix metering unless you know when to use spot or centred.
Ash: I was actually focusing on the orange cart.
It is in fact the Matrix mode that causes the overexposure and has me confused. The center weighted mode actually is the only mode that gives me a decent exposure.
I would expect that Matrix would give me the best exposure followed by center weighted and then spot meter last. That is, if it is a problem with the central portion of the focusing screen.
