When I first started on digital photography, that was really the first time I had to care about "gear" in the sense that I had learned how to use my mom's Pentax MX and the two lenses I had - 24mm and 135mm - and had only made it as far as getting a gift from my dad of a Tamron two-lens kit, a 28-80 zoom and 80-210 zoom. I was able to find a new-old-stock ZX-L at the Ritz camera at the mall in 2005, got that, and used the living daylights out of it, enjoying access to autofocus and aperture priority metering.
[edit: skip to the second half of this paragraph if you read my post "reengaging with photography" from last year, as I didn't realize I basically already told it. sorry.] That all changed when I got my *ist DL, and the company was in the midst of introducing a bunch of new lenses to deal with APS-C image sensors. I actually skipped the 18-55 kit and went with the 16-45 zoom they introduced, as 16 got me out to the 84 degrees I was used to with the M 24mm lens, and then the standard DA 50-200 lens. That kit served me very well for a year and a half, when I got my first limited lenses, the 43mm and the 77mm. At some point in this stretch, my dad got me the 14mm from Pentax, which is still one of my absolute favorites. Through this stretch, though, I of course always wanted the star lenses. The 16-50 would have been nice, but I didn't feel let down in any way by the 16-45 (and indeed, if they were to reintroduce the latter lens, screw drive and all, but with weather sealing, I would be in line tomorrow). The 50-135, on the other hand... the 50-200 served me well but the softness and lack of speed at 200 left me wanting something faster. The pricing was never going to work well for my budget, though.
Until this year, when I decided to take a look at them again. I learned all about SDM motor failure and screw-drive conversions, and decided it was worth a shot. The copy I got for less than a third of what they cost new 15 years ago came out of the shipping box without wanting to autofocus at all. Eventually it got itself to the point where it would begrudgingly swing through the focus range over the course of ten seconds, and I was resigned to returning it. The next morning, I read someone suggesting that this lens could suffer from sleepy SDM, and that one way they were able to get around it was to point the lens at the ground, run the AF, then point the lens at the sky and run the AF again, and that would be enough to wake it up. Lo and behold, the focus is working correctly. At least for a use session, then if I leave it sit for a while, it will slow up again. I figured I could live with that if the lens performed well in the field, and then resolved to take it on a walk before deciding for sure.
Today, I took that walk. The lens performs superbly... at 135mm, which is the only place in the zoom range I wanted to use it. This actually just now has reminded me of my experience with the Tamron 80-210, a lens that I basically only used as a 200mm stand-in because the minimum focus distance meant it wasn't great at shooting pictures of small things really anywhere short of that length. I guess these are traditionally intended to be used for portraiture or general walkabout stuff, and nobody ever thought they'd be on someone's camera that was into little things. The 50-135 worked great for a couple of birds today, even, but it's a lot to keep in the bag for what is effectively something I can effectively do with a 100mm f2.8 macro, or if I were to dig up an FA 135 f2.8, I'd have the same field of view at a fraction of the size. It probably would not do bokeh as well and may not be quite as sharp, but those are trades I can live with in that world.
Anyway, a younger version of myself would not have admitted this. He would have kept this lens and basically let it fall into disuse, believing it had a place in the hoard despite the limitations inherent to a zoom lens. I'm proud of myself for being mature enough to know it's best to let this go to a new home, maybe where someone can convert it to screw drive (since that's not even something you can do on the latest bodies, it turns out).
Incidentally, on zooms: I do have one zoom lens I absolutely adore - the 20-40mm limited. Not only does it feel fantastic in use and produce beautiful images, because the zoom range is so small, the focal distance doesn't create problems with trying to use it at 20mm. I think if they ended up doing a similar lens design that was maybe APS-C only, 40-80mm f2.8-4, same limited construction and feel, I'd again be in line tomorrow for one. I see they made an M zoom in that spec that I may go with just for fun for a while, but I really would like something a little longer that's weather sealed for flowers and bugs. Yes, I do recognize that means I need to stop futzing with it and get the 100 AW macro.
A couple more highlights from the star lens:
