Sorry in advance if this topic already exists, but I can't find it if it does. I can't seem to find any solid info comparing these lenses. A lot of opinions I've read online are completely different regarding the two 100mm lenses. Some say the L version isn't worth it unless you're completely bent on having IS, and that the non-L had equal or possibly better IQ if its on a tripod (for any situation where ultimate IQ is necessary, Id be using a tripod anyway). Others swear by the L as if the non-L isn't even worth considering. Am I missing something significant that differentiates the L other than slightly better build quality and weather sealing?
Also, on paper the 180mm doesn't really seem enticing next to the 100mm considering its price difference. And it seems less available in the used market, so I'm judging their price difference as higher than the difference between their retail prices. But the few times I've seen it mentioned online, people seem to swear by it. Is there any benefit of owning the 180 over the 100 other than it's reach (which I probably dont need... necessarily...)?
I plan on using whichever lens I get for food/product shots... I feel like the non-L 100mm is probably enough for my needs... but as always, I'm tempted by my curse to feel like I need "the best"... the L. (or 180L?!?!?) :-X
I'd especially appreciate advice from anyone who has used at least 2 of the 3 I'm considering. I've read multiple separate reviews on each lens online, and watched the digitalrev 100mm comparison (but I feel like Kai always leans toward the expensive option).
I'm not really looking for votes as much as I'm looking for piece of info that I might have not considered before making a final decision. Im using a 5DmkIII if that matters.
