Re: Images Embedded (pics)

Thanks for the test and the information. To see what you're talking about with these links is kind of hard. I did a similar, albeit more simpllistic test of several zooms and primes at 50 and 60mm:

When I did it, I pasted all the "corners" into one pic using photoshop -- making a mosaic. If you do something similar, it would be beneficial. It's a bit hard to open a bunch of windows...

Thanks again for posting your tests -- I for one find them very valuable...Mike
