Photography – Focus Test

Here's a good tutorial by Bob Atkins on how to check if you have any back or front focusing issues with a lens/camera.

Photography – Deciding on a new lens

So the 50mm 1.8 has done me proud for so long, I find it has too much reach on a cropped body, so I'm looking into a new lens.

Requirements:

• 1.4 - 1.8 constant
• 22mm - 32mm (not converted to APS-C)

The candidates:

• Canon 28mm (44mm APS-C) f/1.8
• Sigma 30mm (48mm APS-C) f/1.4 EX DC HSM - link
• Canon 35mm (56mm APS-C) f/2 - link

The other candidates:

• Canon 50mm f/1.4
• Sigma 50mm f/1.4

That's all the possibilities, now to research which is best....
