I took the day off from work today, so I could play with my K10 and lenses, as well as do some other things.
My gear and I went to the Butterfly Rainforest at the University of Florida in Gainesville and had a great time. As for the waterfall shots, I really couldn't tell much difference in them, IQ-wise. On the red flower shots, the difference was more noticable--the shot taken with the 43 was darker than the one taken with the 50.
For the stats:
Waterfall43--f/4, 1/40 sec., ISO 100 (top left)
Waterfall50--f/4, 1/50 sec., ISO 100 (top right)
Red Flower43--f/4, 1/30 sec., ISO 100 (bottom left)
Red Flower50--f/4, 1/20 sec., ISO 100 (bottom right)
The F50/1.7 is not a bad lens at all, but the one major drawback to it is that the AF is LOUD. When you're dealing with butterflies, sudden loud noises aren't a good thing. Since I have the 43, I'm going to be putting the 50 up for sale shortly.
What do you think?
Thanks!
