Chickadee crashes a lens test.
Lens: DA* 60-250 Camera: K-3 Photo Location: My back yard ISO: 100 Shutter Speed: 1/350s Aperture: F5.6 
Posted By: normhead, 03-07-2020, 12:33 PM

I had some questions about my DA*60-250 after some test images where it didn't do very well indoors at 400 ISO and 1/8s exposures hand held. The question being, was the lens not sharp or was that just to much at 200mm for the SR system.

Turns out the lens is fine, on tripod with the 2 second times there's nothing to complain about.

I had to promise not to harm Tess's stuffed toys. While I was shooting a chickadee interrupted to check if there were any available nesting materials. It was actually trying to pull fuzz from the toys. End of test, the lens looks fine.



I need to buy my own stuffed toys.

Looks good to me, Norm

I don't know if you've started another thread for the purpose, but re sharpness of the DA*60-250 indoors and handheld, I wonder if the SR mechanism is over-compensating, given the focus breathing? If the lens is set to 200mm but, due to closer focusing, it's more like 100 - 135mm in reality, maybe the SR mechanism isn't taking that into account. Just a thought...

Good point, that's likely it. Still, it's kind of disappointing getting that kind of result with a $1200 É4 lens when my DA 55-300 PLM nailed it set at about 200mm and É5.6.

A very nicely captured image there, youngster. Good point re Pentax's SR System. With the K-7 and the SMC Takumar F 70~210mm I'm good. However, beyond the 210mm, I need a tripod.

Again, very nice effort.

Love the image, love the story. There you are, just trying to do a hum-drum test image with random subjects - and you end up with this shot! That chickadee deserves some special feed treat!

Oh, and yeah, blown up in flicker, all the text is sharp and clear, as is the weave and texture of the stuffed bull dog's "fur" and the light spot in the black bear's left eye.

The lens is definitely good.
Thanks for commenting.

You were looking for 5+ stops from the IS system, I have done that a couple of times, but canít do it regularly

However, I was able to make the same shot consistently with the DA 55-300 PLM. Hand held, the weight can make a difference.
