paying a couple hundred more (plus size and weight) on EVERY lens doesn't sound like fun.
The Canon 300mm f4 IS lens is actually cheaper than the Pentax DA* 300mm f4.

Yep that works for me all the time!
I get sharp photos taken at 0.4" sometimes.

Why is everybody so easily excited?


blur-free, noise-free is a no-brainer for a web-sized image. The originals are probably more impressive.

But as I said over and over again, web-sized images cannot show that an original is good with regard to noise and blur.

My own experiments with a K20D with active SR show that at 50mm, original exposures show sufficient lack of blur at 1/8s and shorter (about 8 pixels blur region, but with mild blur intensity(*) only )

(*) See my attachments, a representative example :
- subject at web resolution (full image at this magnification would have been 700px wide)
- subject at 100% crop
- subject digitally corrected for 8px wide motion-blur afterwards

Blur w/o SR is equally distributed within the blur region (and can be corrected). The blur is strongly visible. Blur with SR is smaller and more mild (more centered around the correct location) but heavier to correct for. The blur is weakly visible.

I agree with what your saying but for many people, web sized images is the intended output. That makes it exciting !

Okay I'm tempted to post the 2400x3600 image, and while it's not the sharpest of images, I think I wouldn't have done any better with a tripod, especially since focusing with almost no light is a complete pain.

So? Its not the same lens. Compare it vs the Canon 300 f4 non-IS (though I'm not entirely sure they make one) The point being that every lens from the same maker will cost more with IS in lens.

Shake Reduction???

I have the K100D.
I am not at all sure that the shake reduction is working.
Is there a way to determine whether or not it is operating?

A special symbol lights up inside the viewfinder when it turns on. It takes about 0.5 seconds from the moment you depress the shutter button halfway.

Little question here:

What did you do for post processing. I mean where is the noise in the first picture?
My camera can't do this! It's supposed to be the same as yours but i never go in the ISO1600 territory. This is a scary place way to noisy.

I would love to know what you did in PP!

I opened it in Adobe Camera Raw, made some adjustments to the Exposure (from 0.00 to -1.20), Shadows (from 5 to 12), and Contrast (from +25 to 0).

That's about it.

Here's the image, from RAW to JPEG, no changes made:



Here's a link for the full-size image, and yes, there is some noise
