That was quick

, I remember someone else saying you'll end up buying back another 70-300, I can't prise it off the camera.
Or if you could face it, try a new 28-200 as Nevyn72 shows it looks great to me.
I'm deeply frustrated at present with tele lens options. This is how it seems to me at the moment:
- 70-300 - probably the best of the lenses in this range I've had. When it focussed, the IQ was very good - but, at least on landscape shots focussed near infinity, there was too much AF variability - so getting sharp shots of distant objects was a crap-shoot.
- Lumix 70-200 f4 - bigger and heavier than I'd like, but the test copy I got was badly de-centered and even where it was sharp it wasn't exactly wowing me given its price.
- Lumix 70-200 f2.8. Too big and heavy.
- Sigma 70-200 f2.8. I really liked this lens when I used it - but size and weight are against it, as is the quasi-permanent tripod foot.
- Sigma 100-400. Decent IQ, but in the end more reach than I need and bigger than I need.
- 28-200. OK, so I got a crappy copy. But even so, I think at £900 it's way overpriced. For not a lot more I can get the new Sigma 24-70 f2.8 and it's stellar (not in the right FL range of course, but just drawing a comparison of what you get vs ££).
And that's it!
I think I'm going to try a Sony A7CR (or A7R IV) with the Tamron 28-200 and see what I think. The ideal solution would be for Tamron to bring that lens to L-mount, but given that they have not signed up to L-mount (and IIRC are part-owned by Sony), this is somewhat unlikely.
