am wanting a sharper lens for micro shots of plants/fungi/water drops..from a close distance.... i usually use a 35-70, and am thinking of the 50/2.5. i chose this because i can use it for astro night shots as well, & it is said to be sharp (i would sell my 50/1.8 - & prob use some ext tubes on 70-210 if i need a longer reach)
i also have a 50/1.8 & am wondering if i should keep it & get a 100mm macro - which is better for macro but not so useful for night shots / twilight shots as the 50/2.5 would be
am i missing anything?
