40/2.8 or 50/2.5 macro?

Which is the sharpest of the two? And which is the best?

Oh, Fullframe all the way.

Seem to be two different sorts of lenses. The 40 is reliable and sharp and very light and compact. Nice fun lens.

the 50 is a macro, albeit just 1:2

You would expect the 50 to be sharper for macro use at least, but I have never used one.

From a review. lol.

http://www.the-digital-picture.com/Reviews/Canon-EF-50mm-f-2.5-Compact-Macro-Lens-Review.aspx

The Canon EF 50mm f/2.5 Macro Lens is very slightly soft wide open, sharp at f/3.2 and very sharp after f/4-5.6. Color and contrast are very good. Full frame body users will see some vignetting wide open.

There is so much more to a lens than sharpness... best for what?

I actually own both, and it has never occurred to me that one of them is "best", somehow. They are quite different. Despite the similar focal length, they share very few properties, except perhaps the sharpness - they're both very sharp, even from f2.8.

The 50mm f2.5 was released in 1987, while the pancake is a brand new design. AF is precise, but slow and a bit noisy on the 50 f2.5, while the 40mm is rather quick and much more silent. The 50 can focus much closer, of course. It has fewer aperture blades, 6 vs 7 on the 40mm, so your OOF highlights will look a little nicer on the 40mm.

The 40mm is really small and weighs just 130g, the 50 is small and light, too, but cannot compete with the pancake, of course, at more than double the weight, 280g.

Hi

My research has shown the 50/2.5 to be the little bit better, but macro normally is very sharp lenses :

  • Which one is the sharpest? I would tend to say the 50mm macro (from my very limited try at the store)
  • Which one is the best? For what? By far the 40mm f/2.8 and this has almost nothing to do with the optics. When making photos of people, people feel much more relaxed with the 40mm. The camera becomes like a slightly bigger point and shoot. People has much less scared, especially when I explain that I use it in the Professional mode. I use it for indoor portraits and for street photography, and now it's on sale for $150. I paid the full price 3 month ago:-( Good optics and fantastic "cute" factor.
