[LRFlex] A blessing and a curse.

As most of you know, I'm having an absolute ball with Leica glass on a Canon 
20D.

However, the 1.6 magnifcation factor is both a blessing and a curse.

As a wildlife enthusiast, I find the boost in the 400 Telyt + 2x converter to 
an effective 1280mm a huge asset. Not to mention a money saver - not having to 
buy a bigger lens!  Another big plus is that this combination (at least, using 
the old SL 2x converter) suffered noticeable vignetting.  It still does, but 
with the smaller, 17x23mm sensor,  the vignetting does not apear in the final 
photo!

If you doubt this, compare:

grebe.htm

The  big problem with a 1280mm lens combo, is the incredible lack of Depth of 
Field.

Out at Tunkwa, the day before yesterday, I saw a marmot... and the marmot saw 
me.

See: http://www3.telus.net/~telyt  and then click on Featured Photo.

This shot is sharp as a tack ... see his (her?) right (our left) eye. Yet the 
DOF is so small at such focal lengths, that the nose and teeth are fuzzy, to 
the point where the entire photo looks unsharp.  And closing down does not seem 
to make any appreicable differrence, at least until you get to the point where 
you can't use the viewfinder, and it all becomes pointless.

Still, at high ISOs, the performance in all other respects, is remarkable.

Comments and criticism on the marmot (or any other shot) welcomed, as usual.

Thanks for looking.
