Had some decent weather this weekend so I spent an hour or so at the former golf course playing around. Here are my impressions.
Pros
- Handling isn't bad for such a large lens. I got it balanced on the gimbal and tripod, and it's fairly easy to line up.
- The gun sight is easy to use, and essential.
- It's amazing how far this thing will "reach".
Cons
- Focusing is a bitch! I tried a variety of methods, including 2sec mirror lockup and bumping up the ISO to get a fast shutter speed. Still, I can't really nail the focus, which is frustrating. I've been using my eyes (not great) and the focus confirmation beep, but still it's slightly off. I know I can adjust for specific lenses. Can I adjust for this lens? I guess I'd need a focus chart two blocks away.
- While it handle fairly easy for a large lens, capturing birds in flight is tough! I did get a few airplanes that were merely specks in the sky, though.
- Contrast of images is low, though they spruce up fine in PP. Also, with such a long focal length, any haze at all will reduce the contrast of the image even more.
- As with many of the older lenses, fringing is evident and you really need to watch the exposure and composition, and you'll still need to clean up many shots in PP.
Overall, though, this is a fun lens, and a keeper for me. I guess this crosses over into the "collector" realm. It's fun talking to the other photographers about the lens and Pentax (had one lady with a Canon rig and L lens tell me how envious she was). From that standpoint, it's fun.
Now for the shots. You can see all the images
in this set. You can see the full sized shots as well.
All shots were either f/8 or f/11 with ISO ranging from 100 to 400 (maybe even 800 on some).
Never could get this tree in focus. It was about 100 yards away.
This stump was about the same 100 yards away.
This lady was out walking the golf course. She was around 50 yards away.
The ubiquitous brick wall shot, from about 40 yards away.
I cheated on this shot. Shooting at an angle pretty much guarantees that
something will be in focus. Still, I think it's a fun shot.
Extreme crop of an airplane in the distance. I couldn't make out what it was by eyesight.
And, finally, my pathetic attempt at capturing a hawk that flew fairly nearby (maybe a 150 yards or more).
All in all, it's a fun lens to use, but hard to get exactly right. I still have lots to learn with it, and when I do "nail" the shot, it will be even more rewarding.
