Guess that lens!

tybeck · 05-22-2008, 08:28 PM

A little quiz. Pick the photo that came from which lens. Both shows were taken at the f/4.0 1/50. One lens it a Pentax A 100mm /4 Macro and the other a Vivitar 105mm /2.5 Macro. No PP, straight JPEGs from a K10D. Tripod and remote used. Click to enlarge. My basil plant died, so sage will have to do.

#1

#2

viv 105 is #2

DJey · 05-22-2008, 09:23 PM

same here.. Viv is #2..

k100d · 05-22-2008, 09:36 PM

can't tell...
the focus points are slightly different
for example the yellow flower bud is blurry in the second

I'll go with #1 is Vivitar 105mm but you forgot to set the white balance to tungsten

. Without 100% crops, identical focus and proper white balance it's hard to tell. Even then, I might be at a loss!

Judging from the background size, my guess would be the Viv 105 was used to take #1. Otherwise, I will agree with cmv. Without 100% crops - it is almost impossible to tell which is which.

VIV is #1 for me.

lbam · 05-25-2008, 04:54 PM

My guess is its neither, and maybe a Tamron 70-300 or something...

Peter Zack · 05-25-2008, 05:48 PM

ok, time to award the prize...

Raybo · 05-25-2008, 11:36 PM

I don't think anyone can really tell................not me at least!

Both are really good lenses and the compairasion is not fair, GIVE IT UP!

Vivitar is #1? (no pun intended)

lbam · 05-26-2008, 03:38 AM

Actually, that background looks a little too out of focus for my first guess...

I think homeslice forgot he made this post and we will be left here w/o an answer forever.

Viv is #2- it has a slightly warmer color tone.
