ok showing total ignorance( surprise surprise) but with a say 100 mm f3.5 macro lens can you only use it for close up or can you use it for any 100 mm shot ,macro or not...guess i don't get what makes a true macro lens a true macro lens...reason i am asking is i was looking at some shots taken with one that looked like a normal distance shot, rather than a close up so i wondered all the ways a lens like that could be used.
Thanks
No, you should also be able to use it as a 100mm normal as well. One downside to macro lenses are that they can tend to seek into the macro focus range if they do not initially lock on to focus at distance. With my 50mm it has led to a few lost shots because of the seek factor.
Now with the 50mm macro (as an example) if you are also using the 1:1 converter, you will be locked in to only macro with that combo. Without it any range is fine.
