Originally posted by leekil I've typically used a lens that is small enough to stick through the fence. I would think that the 50/2 would fit, but I have used 40mm and 43mm. Maybe DA35?
The DA 35 Macro can be used as a normal lens (almost 50 mm equivalent on APS-C), the built-in hood has a diameter of 55 mm.
The diameter of the original hood MH-RA 49 on the FA 43 is 54 mm.
This hood can also be used on the DA 40 (looks very good).
The DA 21 is still the winner with a hood diameter of 51 mm, and additionally it has a square opening of only 34x25 mm so you can peep through very small openings indeed if they are not too deep.
It also depends on the focal length you need of course.
