Dearest Don, thank you for your kind advice to a LUCKY beginner like me on what are 'prime lenses'.

 

<p>

 

Can you answer my question instead of mocking a beginner on a wrongly used term?

to clarify on the term 'non-PRIME'

 

<p>

 

what i mean are the lenses with same fixed focal lengths but not the L lenses

Can anybody give some comments on various Praktica (my body is a BX20) and Leica lens (my body is a R3)? My praktica lenses include 50mm 1.4, 28mm 2.8 and especially the 20mm 2.8 made by Carl Zeiss. My Leica lenses are the 135mm 2.8 and 240mm 4.0(i forgot their real names, but i think they would be the conventional ones). What i mean is, how are they compared with the canon NON-prime counterparts? (distortion, vignetting and lens build and quality). Thanks a lot.

i owned a praktica BX20 and a second hand Leica R3. unfortunately, i got only 2 telephoto lenses for my leica. can anybody suggest a solution to mount a praktica 20mm f2.8 onto the leica, or canon eos a2?

Ques 1. How can I use the build-in flash to take a photograph of a low toned person against a mid tone wall WITHOUT letting the flash washing out all the details on the wall? (will it be a miracle to do this?)

 

<p>

 

Ques 2. How does the EOS A2 16-segment metering system works. In what situation will it works better than the center-weight metering mode?

Thanks a lot.
