For all the shots you guys are talking about there are f/1.4 lenses that close focus available for $50 to $100 and are much better suited for those tasks - especially on µ4/3 where you also have a selection of 30 or 40 such inexpensive lenses - many of which are hella-sharp at f/2.0!. When you get down to between 1:6 and 1:1 reproduction ratios no one human can tell the difference between 2.0 and 3.5 - which is the slowest one I listed above. With some of the others we\'re talking about the difference is between f/2.5 and f/2.0 . And it\'s pretty rare that anyone would want to shoot at those magnifications near to it\'s widest apertures - it happens but it\'s rare!
So yes, I\'m assuming quite a few things all of which seem only to be common sense.
Wanna take macro shots - get a macro lens.
Most (all?) macro shots need to be stopped down to see anything almost at all. The DOF at those magnifications is just too narrow!
There is no humanly detectable difference between 2.0 and 3.5 at macro magnifications - let alone between f/2.0 and f/2.5...
For portraits or flower shots like above there are way better options available without having to spend an extra $400 on a macro lens that opens (only) to f/2.0
Most macro fanatics know that the hobby requires a good command and understanding of light, lighting equipment, and technique - the difference between 2.0 and 3.5 isn\'t hardly going to save anyone ever. And for sure never between 2.0 and 2.5 - etc.
The Zeiss 100 2.0 is a bit of a different story as it produces images at normal and far distance focusing which are quite unique with only a few other lenses capable of the same. In that case the person might want it specifically. And also 2.0 is quite fast for any 100mm lens - macro or not - whereas f/2.0 on a 50/55/58mm lens is pretty darn slow and not worthy - again, macro or not.
But that\'s just how I see it. I\'m not out to convince anyone of anything. I do like sharing my thoughts on a topic tho.
So here you can see the non-macro Olympus OM Zuiko 50/1.4 with only a slight crop and not yet to it\'s minimum focusing distance either:
1/500s, f/8.0 or f/11, ISO 100, GH1, Reproduction Ratio: Between 1:12 and 1:15, - processed of course.
