Originally posted by clawhamemr it seems to me that it is not possible (financially) to make a sub-2.8 macro. A little searching shows a canon 50mm f/2.5, but it doesn't seem that anyone else has made something that fast in a macro.
A little searching further:
Zuiko D 50 f/2 (Olympus already did have a 50 f/2 and a 90 f/2 macro for the OM-system)
Carl Zeiss 50 f/2 and 90 f/2 (although it seems almost impossible to obtain anywhere)
But al thes lenses are not full macro's; they're only going to a 1:2 ratio, while the macro limited goes life size... I think that is essentially the trade off (apart from the money
) for a sub f/2,8 macro. Thinking about it, then I'm glad they stopped at f/2,8 and concentrated on the image quality...
