Someday I will get a good photo of a male cardinal, never any detail, until then I aim for the females!
What lens are you shooting with? I'm seeing 700mm f/4.5 in EXIF

Here are a few backyard birder shots. All are with the K-3 and Pentax-M 400mm f 4.5, a nice lens for this purpose, I think. At 0 degrees F, they birds sure seemed to appreciate the sunflower seed, suet cake, and peanut butter/cornmeal mix!
Damn, your birds are living the high life! From me they get mostly cracked corn, with some millet and sunflower seed.

Sorry I did not get the exif data set correctly, its a SMC A * 400 f2.8 with the Pentax AF 1.7 adaptor. Technically a 680mm but I set the lens length on camera to 700 for the shake reduction [I have not really tested the SR at this lens length to see if it helps at the shutter speed I was using]. I used this set up today with the cardinals and this fox...

Oh, you set the EXIF data correctly, I just couldn't figure it out!

In my experience using the AFA 1.7x with a 300/2.8, I needed to stop down a bit to get decent results, not just for sharpness and contrast but also because depth of field is so thin, particularly when backyard birding.

Please pardon me for interjecting. However, SR should always be set at the stated lens designation, i.e., 400mm, not the equivalent focal length created by use of an extender, different sensor size, etc.

I disagree.

The Shake Reduction should treat the glass assembly as a single lens. SR works on the camera movement as determined by the body sensor, and then calculates the rate of subject movement on the sensor based on the magnification of the whole assembly, including extender. It should NOT be adjusted, as you say, for any fictitious sensor size factor. The subject movement on the sensor is proportional to the change in focal length.

Just a shilouette & sunrise using a 1/2 purple filter. 28-300mm lens. I also wonder why there is not a category for shilouettes like nature, landscapes etc...

Hello Kombivan,
Camera shake shouldn't have been an issue with this pic...1/8000s should stop anything.
High shutter speed is the best cure, and if that's not possible, use a stable object (tree, post etc) to steady the camera.

Cheers,
Terry

Perhaps I am incorrect on this. I was only parroting what Adam told me when I asked this question.

I've been a little critical of the FA*400mm f/5.6 on digital - it felt at times like it couldn't handle the pixel density of the K-3, but I'm wondering if slightly higher ISOs are the way to go - I was more pleased by the sharpness of this sparrowhawk visiting our garden in rather poor light, hence ISO1000, than with some of my other shots at lower ISOs.It might be something entirely else, but worth exploring.

My experience with shake reduction on a telephoto, my A*400 f2.8 only. I have tried various "lens" settings on my K-3II with this lens. With and without the 1.4-XL and the AF1.7. All on a rather heavy and stable Bogan tripod, with and without SR enabled. Always with a wired remote. So far SR seems to produce better results, but not always. Operator error is usually the case there! Last night I spent about 3 hours reviewing many SR discussions and recommendations, something I should do more often. There seems to be no set in concrete answer for older telephotos and SR so I just experiment with my equipment to see what works best for me. Against the advice of more experienced users and Ricoh/Pentax, I have SR on most of the time with my tripod. I recently, for the first time, tried the 400 on my equally beefy and sturdy Bogan monopod. That I may not try much, the lens is like a nose heavy 13 pound weight on a stick, even though I have a camera strap and a lens strap [attached to the lugs] for safety! I was overly careful, which was not enjoyable! But the SR worked well on the monopod with the lens and AF 1.7 length set at 550. Next time I dare to try the monopod I will set the lens length at 700. This is my experience, others will no doubt vary. On a side note, I had to decide what my first shot with my new camera was.... Haha!

You've effectively got a 1000mm f/4,5ish lens there on APS-C - you could do some nice moon shots with that
