It would be interesting to see what the real-world impact of the OIS in the Panny would have on IQ. If you assume it's worth 2 stops at 200 mm, and are talking about ISO 100 with the Panasonic vs 400 with the Tamron, then I suspect the Tamron would still have better IQ, unless you are heavily lifting shadows. On the other hand, a blue-hour shot that requires ISO 1600 with the Panasonic would require a faster shutter on the Tamron and thus push the ISO to 6400.Sorry, I ought to have prefaced my post by saying that I want a decent 28-200 The Panasonic 28-200 is not a good performer. The Tamron 28-200 is really rather good.
Not sure how that would turn out in an IQ contest, but I could simulate that with my existing lenses, I suppose. And, if there is some shadow raising needed, etc. Especially on an S1R. This is of course all theoretical, as the Tamron isn't available on L-mount, but a fun little mental exercise.
Anyway, I'm stretching things a bit, but I certainly have to disagree that the Panny is not "good." I think it's an excellent performer up to 180mm. And the stabilization can pay dividends, especially at 200mm, which is where the Panny needs help.
I'm not sure which I would buy if they were both available on L-mount. If it were my only lens (other than maybe an UW zoom) then I'd probably pick the Tamron. But if I had better lenses to fall back on when IQ was considered crucial, then I think I'd prefer the smaller & lighter Panasonic. To me travel zooms are "fun" (or convenient) lenses, so I'd rather have the smaller lens, particularly since it has OIS, which just adds to the "frame it and shoot it" nature of this kind of lens.
But it is too bad we don't have the choice.
Thanks for your notes on the above.I’m really not looking for a system switch, but I did a comparison of the A7CR plus 16-35 PZ and Tamron 28-200 versus the S5 plus 14-28 and 24-105. It’s notably smaller and 350g lighter, and offers 200mm reach vs 105. I could also drop my S1R as well. It’s very tempting. But, no Live Composite, and the EVF experience isn’t as good.
Nikon Z is nice, but I did run a Z7 system for a while a few years ago. I found the lack of zebras for stills a major limitation for how I use a camera (although I’m told there is a workaround that I was unaware of at the time). I also found that the camera felt a bit old fashioned in its firmware and operation compared to Olympus, which I was using at the time. Panasonic cameras are just as modern feeling as Olympus, and in some ways better.
