So few weeks (months?) after I initially found the issue with this specific combo (this thread
SR inconsistencies - PentaxForums.com), and few trips to different locations with it, I'm positive that I'm either outside of the spec or expected results with my combo, or that SR (or whatever causes the issues, tbd) just doesn't work well with this lens. It behaves differently with say smaller 50 primes or my tamron 70-200, I really want to try to determine what could be the issue. As i mentioned in another thread, at wide setting I can't get tack sharp results hand-holding after 1/25, but can get very sharp images under 1/25, and also anything beyond 1/250. What's annoying is that due to slower aperture of the lens, and the sweet spot of it being at around f8, I rarely can get enough light with 1/250 without turning up the iso which I would prefer to avoid. So I either need to turn aperture to very high values f13-16 to work with 1/25 and under (not ideal of course), or turn aperture down and try to achieve a good exposure at 1/250 +. It's quite limiting, and while I love the results I'm getting out of the lens and I like the build quality, and convenience is immense (weight + size). But if I can easier get better results with the DFA 24-70 (meaning higher range of usable shutter speeds), then I'd rather sell it and upgrade to that. So, if anyone has this kit - I'd love to hear your experience (and sample photos if possible
), does my case sound like it's out of spec, and possibly warrants a warranty repair?
Thanks!
