Howard -

You're comparing the f 2.8 performance of a 24 1.4 lens to a 28 2.8 lens?

Yup - with both lenses at f2.8


I think that regardless of origin, most narrower lenses of modest aperture will outperform most ultra-high-speed (for their focal length) wider lenses.

Agreed - but it was interesting to me that the incident angle of light striking the edges of the CMOS in the 20D produced colour fringing from the 24mm lens and not from the 28mm lens. It would be interesting to compare the 24 Canon with a 24 Elmarit (although not one of Leica's great lenses) or the 28 Elmarit with a Canon 28 (although not one of Canon's great lenses). Of course, in the center of the picture both lenses perform very well.



Regardless, I'm glad that someone with your level of experience took the time and care to compare the two in a responsible way.

Thanks Bob, you aren't pulling my leg are you? ;-) Howard

Why not just leave the adapter on the body. It much simpler that way.

Hello Again,
I have two adapters - which allows you to have two lenses in play at once and I never seem to need more than that. Main reason is I rarely go out with more that two - generally the 28 Elmarit and the 90 Summicron - for "widish - near standard" views and medium tel views. I could get by with one adapter I think, but the second one is handy. I would start with only one and see how it goes. BTW I have tested the Canon 24 f1.4 against the 28 Elmarit f2.8 and on the 20D in the corners you get less colour fringing with the Elmarit than with the Canon with both lenses set at f2.8. This is a real tribute, IMHO, to the quality of Leica glass - because the Canon 24 is one of the best Canon wide angle lenses - or so I am told.
Cheers
Howard

Dear david,
About metering - what garbage!!! - the metering works juts fine in Aperture preferred mode and is very accurate in my experience. If you get one of these babies you won't go back to film - I bet on it!

Thanks, Howard. That's what I understood, and couldn't quite believe the fellas.


OK - last dumb question (for now). Can you conveniently get by with one LeiCanon adapter, or do you really need one adapter for each lens you wish to use?

I'm getting very tempted!

and Kong Hei Fat Choi to you too! May the year of the Rooster be good to you! :)

Cheers!
