In reply to jethro kiernan:
I used the ftz adaptor for a while - now sold. It works well if you mount it directly to a tripod with an Arca Swiss plate attached to the base, particularly for a telephoto as it helps with balance. I used a cheap one from a company called Andoer on Amazon. There is just enough clearance to keep an L bracket on the camera - I use the Three Legged Things one made for the Zs (ridiculous price but very well made).
I ultimately went with the Z camera over the Sony because it just felt like a more solid/ ergonomic body and after handling it, I just couldn't see past it and haven't regretted it. I have owned another Sony before and it felt more of a computer that took good photos than a camera - fiddly and not intuitive.
The other reason I opted not to go with Sony was the cost of the lenses. There is no doubt they look fantastic and wide ranging but the GM lenses are well beyond my price range. The Tamron options do look very attractive/ affordable if you don't mind the odd focal lengths.
I can definitely recommend the Z 14-30 and if you want a fast prime the 50 1.8 is both the cheapest and sharpest in the Z series. I have a few photos on here with both of those - although definitely not representative of their full potential.
The 24-70 f4 kit lens is also really good and a steal second hand/ as a kit, but I sold mine to get the 24-200 when it comes back into stock. For landscapes the latter is supposed to be just about as good as the 24-70 at those focal lengths, weighs about the same and saves you carrying a heavy telephoto.
Look forward to seeing your photos whatever you get.
