Actually, it is absolutely a dog, and most people who have dived with it agree (even in this thread).

The original post asked about the 50mm macro, the feedback was that the lens is not worth the $. My suggestion was to get the new 100mm, it seems to be much better than the 90mm (which is better than the 50mm).

The fact that you like the 50mm means just that, you are one of very few that like the 50mm for macro (and it's unlikely you've ever tried to shoot it for blackwater).

Why would you shoot with a macro lens that struggles with AF for small subjects?

And...first camera was a Nikonos III, new.

That's your opinion. I don't share any of it, just as you don't share mine.

And FYI, no need to mis-quote me. I didn't say the 50 struggles with ALL small subjects. I said some, eg. thin ones. With other small subjects it is usually bang on, straight away, esp with a focus light in dark conditions. No different to other macro lenses in that regard.

Best if we agree to disagree.

Still on semantics? First camera Nikonos I (actually it wasn't called a "I", just Nikonos...). I still have it.

My Nikonos III came much later...

To be fair, I didn't misquote you - I never suggested you said "ALL small subjects", however you clearly misquoted what I wrote.

The point is still the some - the 50mm lens is a dog, it struggles to focus on small subjects in situations that other lens do not.

I have the opportunity to dive with an A7RV, a D850, a Z8, as well as an Oly on a regular basis in our family. The 50mm lens on a Sony is the poorest of any of the typical macro lenses used across any of these. This isn't just opinion, this is from experience.

The 100mm looks to be a much better macro lens for Sony shooters. Alex suggested this is true, other shooters who have access to the lens are saying the same. Feel free to stay in the past, that's completely your choice.

What could possibly be your motivation for suggesting somebody else follow you down this path?
