Testing focus on DA 70 Limited

Rest easy. A camera/lens combo needing an AFFA adjustment is by no means unusual, even with a Limited or 'Star' lens. There are an awful lot of ones and zeros that the camera's AF processor has to deal with when it's evaluating a scene. As new camera models are released, their AF algorithms and processors improve. But there will always be some manufacturing variances in lenses and cameras. Maybe an optical engineer can explain why some lenses have a better AF hit rate when focusing in from infinity rather than out from close-up.

Maybe not helpful for your K200D, but you may want to watch the Youtube video about the 'Dot-Tune Method' for AF fine adjustment. I found it interesting and instructive.

If you decide that one of your 70mm Limiteds is absolute trash and you want to sell it for a song, be sure to PM me. :) But I'll bet there is nothing wrong with them.

Too obvious I suppose, but lens hoods and polarizing filters are a must-have. I've got stuff crammed into every nook and cranny in my bag. One of my newest favorite accessories is my Moman mini tripod. Then there's the automotive windshield shades, which I use as light reflectors (or shades :) ). Very light gray on one side and silver on the other.

K-3 Mark III reviews in the Japanese press

Great summary JPT; thanks for taking the time to put together your post. The more I learn about this camera, the more I think it is unfortunate that Ricoh decided to call it a K-3 III. This camera is not a further refinement of the K-3 series. It has a new sensor with more megapixels. It has a joystick. Size-wise it may be similar, but IMHO it deserved a new model designation. To my mind Ricoh would have been better served marketing an entirely new model instead of a perceived re-tread of an old model. My two cents. Maybe they thought the K-3's reputation would help sell these?

I bought a DA*60-250 to shoot offshore icebergs on my (canceled) trip to Newfoundland last year. I still refer to it as my iceberg lens. :)
I've been following the news from Texas - best wishes for a speedy recovery.

When I got my Pentax-F 100mm Macro I had to get used to how razor-thin the DOF was at close focusing distances unless I stopped the lens way down. What was your aperture setting? My lens (and undoubtedly yours) is so sharp that people say you can shoot at f/16 and even f/22 with very little diffraction softening. According to A Flexible Depth of Field Calculator, for a 1.5CF aps-c camera with 100mm lens focused at 1 foot, the DOF at f/8 is 0.08 inches. At f/16 it's 0.16 inches. You get 0.24 inches at f/22. Back away to 2 feet and the DOF numbers go up to 0.39 inches at f/8 and 0.83 inches at f/16.

For macro shots on a tripod I'll often use manual focus.

Many would argue that obsessing over sharpness is actually detrimental to the thought process of making an artistic, emotionally impactful image. This is a tendency that I fight. Some of my images that get the most 'likes' aren't the sharpest, but have other elements that make them appealing to others. On more than one occasion I've had an image that I thought wasn't quite up to snuff, but then thought 'what the heck, I'll post it anyway'. I've been surprised by how many nice comments I've gotten. But then, members here are generally nice folks.

I can recommend Bryan Peterson's 'Understanding Composition' as a good read to get your mind on the right track for what's important in creating an image. Full of thought provoking and horizon expanding concepts; at least it was for me.

An indoor studio might have limited camera-to-subject distance available due to the size of the room. Just be aware that you don't want to use a 'wide-angle' lens for portraits. You can get perspective distortion that will make people's noses look too big for their face. On an aps-c camera, somewhere in the range of 31mm to 35mm is probably as wide as you'll want to go, but longer is usually considered better for flattering portraits. Also, more distance between camera and subject will make some people feel more at ease.
