Exposure: 0.006 sec (1/160)
Aperture: f/6.3
Focal Length: 50 mm
ISO Speed: 100
Exposure Bias: 0/10 EV

So this time I took the advice I learned from the last critique, and applied some of them to this picture. I didn't have the option in Camera Raw (photo was taken in RAW) to use the Clarity option, but I did apply more vignette.. I took this with an aperture that was wider than before to isolate the droplets in the centre of the leaf..

Water Droplets on a Leaf

I took this shot in the afternoon right after a quick rain. Thought there would be great opportunities for some macro shots of water droplets on leaves.

Exposure: 0.05 sec (1/20)
Aperture: f/11
Focal Length: 50 mm
ISO Speed: 100
Exposure Bias: 0/10 EV

Captured it in RAW (ARW) on my A100 with the 50mm f2.8 Macro, then edited the photo in photoshop CS2 (camera raw for exposure, and then some curves, levels, and unsharp mask). It just didn't come out looking as sharp/contrasty as I was hoping. Looks like there's a gray film over it.

Why the big discrepancy in price on f/1.4 lenses?

I love using big f stop lenses. My favorite was a was an old f 1.4 57mm Konica. Now I'm thinking of buying an f1.4 for my Sony DSLR. With the full frame Sony DSLR coming out latter this year it seems like the 50mm would be a good choice. Sony offers three focal lengths for f/1.4, 35mm, 50mm, and the CZ 85mm. I don't understand why 35mm and 85mm offering by Sony are priced four times as expensive as the 50mm. I must be missing something. Are the others so much better or is it something else?
