The other option that I use, and maybe a few others on the list, is the Nikon
DK-21M viewfinder magnifier. It fits on the Canon and allows a small, yet
significant degree of magnification that really aids in focusing.

I could not use my manual focus lenses on my Rebel with out it. Even with the
focus confirmation adapter. I am not always able to get those focus spots to
light up. Perhaps too dark.

Hello Steve,
I saw where you posted "I put the money towards a XSi body and am looking
forward to using the Live View to help with focusing." As someone who cut his
teeth in photography with fully manual Minolta SRT's, progressed through their
X370 to X700's, and transitioned to the uber techy EOS Film and then Digital
SLR's, I want to pass along an option you might want to consider for your Rebel
re: Focusing your Summicron. That "live view" technology is about as geeky cool
as can be, but using it to chase your kids in changing light and distances
isn't very handy at all. (The word impossible comes to mind!)
I suggest you research getting an aftermarket Focusing Screen for you Camera
to replace the Rapid Return Mirror in your Rebel. Canon has interchangeable
screens as an option in the more expensive models, but the rebels and xxD's
aren't included in the fun unless you buy aftermarket. I haven't replaced my
screen yet, good lenses are a higher priority at the moment! But I DEFINITELY
want to. I carefully researched this topic and there are a couple of sources
you should be able to google up fairly easily. One's called Katz, there's the
very expensive beatty screens, and 1 or 2 other's out there.
I use a 'focusing' M42 adapter with my old Zeiss, but it's invariably
inaccurate when dof gets shallow and when the working distance starts to narrow
up. That sports photo I posted before was prefocused to keep the entire batter
in the depth of field, but on the little 20D LCD I didn't catch that it landed
a bit to in front of him. It doesn't ruin the shot, but instead of relying on
adhoc adaptations of chips and sensors, I could have quickly and easily used 50
year old technology to land my dof properly.
Sincerely
Richard W.

I am currently getting the digest email, so will send all replies in a single
message-
To Doug and Aram,
Thanks for the advice, you are completely correct. Later that night I shot some
test shots on a tripod, and got striking results compared to my other lenses. I
always knew that minor lens flaws should not impact image quality, but this
lens is great even with quite a few marks! I am very happy to have acquired it,
I would've paid much more for a 'minty' copy anyway. Instead, I put the money
towards a XSi body and am looking forward to using the Live View to help with
focusing.
BTW Doug- it was your Leicaflex article at photo.net that inspired me to go
looking for one!
To Richard,
Thanks for the tip. I was actually shooting at ISO 800, my impressions of the
Canon ISO range are the same as yours. ISO 800 is very usable even with a bit
of cropping (and I've never done too much post noise-removal work either.) I
always find myself pushing the limits with my Canon 50mm at 1.8 and ISO 800,
with DSLR's I am always willing to give it a go. I'd rather have a semi-blurry
shot at the 'magic hour' than anything under the harsh early noon sun. That's
one wonderful thing about digital- with multi-GB cards the norm, you aren't
afraid to shoot a string of shots to try to make sure you get a good one if
conditions are challenging (as is usually the case with my kids.)
Cheers all,
Steve
