I also heard about the tamron versions. Are they any good ? I don’t know anything about third party lenses yet for Sony. I am reading this Thread but so much info

I've never used a Tamron E mount lens, though I do have an A mount 90mm macro (great optics for the age). My comment was more that after using a GM prime it's hard to go back to other lenses, although the Sigma Art series are very close optically. A couple of years ago I bought a GM 50 f1,2 and it's my landscape and general use lens of choice.

You asked about the 24-105, and this is what I use for travel/walkabout where there may not be time etc to stitch a piano. Generally performance is great for what it is, adequately detailed even wide open, images can get a bit 'hard' if you push clarity up. It's not astonishingly good, but it is a very useful lens.

Re. Sigma, is there also something about HSM being for the older DSLR's and DN being designed specifically for mirrorless, but HSM will still work? I can't quite remember the specifics (something to do with the flange?)

As mentioned HSM is the motor (hyper sonic motor), and it was used for DSLR lenses. When Sigma first adopted to mirrorless they essentially used the same lens and just added an 'adapter' (really just an extension of the lens at the mount end) to make up for the difference in flange difference. The DN lenses are specifically designed for mirrorless and therefore do not need this 'adpater' and so are smaller and lighter.

I still think the GM's are the best you can get. I see the odd review stating that the odd Sigma Art is better, but they only look at one aspect, when you look at build, sharpness, bokeh, AF speed etc GM still come out on top, however this shows just how good the Sigma Art are if they're comparable.

Those piano's are extremely difficult to stitch

I've had the 70-180mm f/2.8 for quite a while now. No complaints whatsoever and as a bonus it does focus pretty close too - not macro close obviously but certainly enough for flowers, toadstools etc
