So now I have a decent setup with plenty of coverage. Some things aren't ideal, but it will do for as long as it must.
The most recent lens is an older Tamron Di 28-300 VC. It's not the newest and it's used, but the AF speed is a bit better than the Canon lenses. Its close-focus skills are very good, about 3/8 life size. The nose does spin when focusing.
- The 20-60 has weather seals so it's a clear option when the weather could make a difference, the Meike 35mm has a seal at the mount but no others. This suggests I can bring primes for the lower end and zoom after 70 or 100mm, whichever seems appropriate.
- I cannot imagine enough times when 20mm isn't wide enough - and I can stack my own panorama in those rare cases. Also, 20mm f/3.5 seems sufficient for astronomy compared to an f/2.8 lens, so the 20-60 plus 35/2 and 70/2.4 should suffice for sky images.
- As to zooms, I have a few more than I need. The Vivitar 70-150/3.8 works very well and its push-pull makes for nice video zooming. It's not worth much on the used market so its place is safe for now, along with the Nikon-F to L adapter. The 100-300 isn't top notch at its long end, but for now it can stay. The 70-210 is a definite keeper until someone brings out an L-mount model with superior AF, some weather protection and hopefully OIS. The Tamron claims to have VC but my tests showed very little benefit, so perhaps its implementation isn't happy with S5 and adapter. With it turned off it's not a low light champ either, so that might turn off the S5 internal stabilizing; the 70-210usm definitely shows better shake reduction overall.
It's nice to have more functional options! The EF-L is greatly superior to SA-L that I tried earlier, since my old SA lenses were not sufficiently compatible for autofocus.
