I just fired away with the K100D, taking about 600 JPEGs and about 400 RAWs. I haven't made it through even 50 of the RAWs yet, and I only glanced at half the JPEGs.
Originally posted by SCGushue I'm not sure whether or not the rich blue sky was responsible or whether you opened up a stop or so on the EV compensator, but the shadow detail in the planes is fine.
I did several things throughout the day.
First off, I was using the circular polarizing filter on any stills, and even some of the early aerial shots, like the F-22. 80% of my F-22 shots came out blurry as I couldn't get more than a 1/250-350 shutter with the cir-pol on. Once I took it off, less than 10% were blurry, even at the full 3008x2000, as I got 1/1,000.
Secondly, I used shutter priority. I really should have jacked up the ISO to at least 400. It was in Auto and all of the pictures were auto-metered (is that the term?) and came out ISO 200. Then again, they might have had more noise if I used 400, let alone 800. After all, I can't expect a lot out of a f/5.6 lens, although this set does prove that the DA 50-200mm f/4.0-5.6 is a cheap but "good enough" lens for a lot of things -- at least with ample light.
Third, I started with an EV +0.0. But as I started bracketing, I found everything was never any good at EV -0.5, and sometimes best at +0.5 or even +1.0. So I set it to +0.5 and just bracketed at a 1/2 so I was getting +0.0, +0.5 and +1.0. I just "let'er rip" as I shot.
Lastly and luckily, about 75%+ of my photos "centered well" so I could keep almost all of them -- very, very few times were the planes not completely in the frame. It seems the 200mm focal length, 306mm equivalent 35mm, was ideal for most of the altitudes and other distances at the show.
Oh, of one, additional note. I got 500 shots with each set of Energizer NiMH 2500mAh batteries -- so 2 sets did me the day (1000 shots). They were still "full battery" on the LCD, and the AF didn't slack off at all. I just discharged-charged both sets (as well as a 3rd) within the previous week, each battery went to around 2700mAh. When I got home, I discharged each set, and 1500-1700mAh were discharged, meaning the batteries only used about 1000-1200mAh, although much more and I would probably lose the current and AF speed. I cannot stress enough that one must "respect" NiMH for the PITA they are -- not only buy well regarded NiMH batteries (Energizer, Sanyo, etc... -- the All-Battery.COM/Tenergy 2600mAh won't give you that, and fail to read full battery when inserted, likely because they can't deliver the current the K100D requires), but you must do the full discharge-recharge cycle to get maximum effect, and no "memory effect" (which is still an issue for NiMH, although less than NiCD). I still carry a non-rechargeable Lithium set as a "backup," should I run into any issues with my NiMH.
Originally posted by SCGushue This is quality work. I hope that they are this sharp full blown. If so, you are doing a fine job.
At 1/1,000 shutter, they are pretty good. I probably need to play with the JPEG contrast/sharpness, I was using the base 0/0 (+1/+1 next time?), although I thought they were still pretty sharp at the full 3008x2000. It was bright, but not too bright. I stupidly left the ISO at 200. Had I not, maybe I could have gotten a little better shutter and/or used a polarizing filter.
I can send people full-sized 3008x2000 copies via YouSentIt.COM or another site for closer inspection.

Oh, when the American football season starts, I'll make you guys at least "indirect" fans of my Alma Mater! That's the main reason I bought my K100D, for football. Booster on the 48 yard line bay-bee! We can go 0-12 and I'll still be there. In fact, we went 0-11 a few years ago, but no one was getting my season ticket!
