Yes, I know “it’s a feeling” is very much the biggest factor. Obviously if a lens is just useless, then it’s useless, but once it’s “decent” then it’s the intangibles that come into play.
I’ve owned the original 55-300, then the WR, and finally the PLM. That gets me back to, I think, 2009. It was until very recently my “long lens”. The 150-450 came about because I wanted more for birds. But still, 300 is mostly enough for aviation. Even if only because the 150-450 would be unwieldy all day at an air show!
The main weakness of the 55-300 is the aperture. Way back when, I tested the original and found its sweet spot was f/11. With PhotoLab, and particularly DeepPRIME, I allowed myself f/8, and the PLM, I think, is just that little bit better and so I’ve fallen back to f/7.1
This is where the 150-450 spoils me. I just leave it wide open. Not that that is very open, but it makes a difference with fast moving subjects!
My full pantheon of lenses is:
HD D FA 150-450mm AW
HD DA 55-300mm PLM
HD DA★ 16-50mm PLM AW f/2.8
smc DA 18-135mm
smc F 35-70mm
smc FA 50mm f/1.4 (original)
smc M 200mm
smc M 50mm
smc M 28mm
Tamron AF SP 90mm Di Macro
The vast majority of the time I use the top 3, though the 150-450 and 16-50 are less than a year old and before that I used the 35-70 and 50 1.4 a bit (a sweet lens).
The Tamron does fine service at the moment to digitise old negatives and slides, but I should spend more time outside with it.
The two shorter M lenses were my Dad’s, bought in the 1970s.
The 18-135 is interesting. A really useful focal range, but I stopped using it years ago. Long before I got into PhotoLab at v3. Quite recently I put some old shots from it through PL8 and was surprised how good they came out! It’s a real testament to the lens sharpness correction in DxO’s modules as without it, the photos are very mushy on the edges.
