70-200/210 which to buy?
The DA 50-200 is pretty good (IMO not as good as the F 70-210) and can be had for quite low prices.
If you want Manual focus then the A series 70-210 f4 is superb quality and fixed aperture throughout the range. These often sell for under £50 - which I think is top value

Hope that helps

If you do not need autofocus you can often pick up the A70-210 for a reasonable price whereas the later F70-210 can be expensive.
You should be able to get a non-WR DA50-200 at a reasonable price too.
If you want AF then the F series 70-210 is noisy but has excellent IQ - it's not always easy to find at a good price nowadays and you have to watch out for lens separation between the front elements.

The older lenses can be pretty good, but they are quite a bit heavier and bulkier.
Best regards, John
The DA 50-200mm has the advantage of WR,
The DA50-200 is NOT a WR lens.
You are confusing the original lens with the later DA50-200WR.
Lurking is shirking.!

The 55-300 is a great option if you can afford it, but the Tamron 70-300 (which has the advantage also of being FF compatible and having an aperture ring so usable on film bodies too) is stupidly good value for money. Very long warrantee too. I have the Tamron as I don't need telephoto very often and it's good enough when I do. Compared to the 55-300, there is less vignetting and centre resolution is higher. But the DA lens has better borders at longer lengths, better contrast, and less fringing/CAs.
