Nice ducks and hummer shots!
I've had my feeder up for 2 weeks, and still no sign of the little buzzers.

Hans,
Looks like you have a winner on your hands with the 150!

Amy,
Are you sure those are wood ducks?:hmm::lol:
Terrific Aix sponsa and snail shots!!
(man I love Google!)

Excellent shots Amy!
Can't wait for the goldfinch to get back to their summer colors.
We have a large river birch tree, and before long it will be filled with goldies feasting on its seeds.
Hope my skills with the Q are up to the capture task.
(boy are their highlights easily blown out though)

Fess up Amy, you're a taxidermist on the side, right?:lol:
Or you put something in the water to sedate the critters!:p

Nice shots, and comparisons,
Thanks for posting!

Thanks for posting, they both look great on the Q!
Looks like I need to get the C adapter, and look for some of these little guys.

Really neat photos oldbike!
Would love to see the lenses on the Q too, if it's not too much trouble.:)

First, my disclaimer.
The tech side of photography is not my forte.

This lens is not the DI version.
Fotodiox adapter, black felt inside.

All shots at f/6.7, tripod mounted, using the 2 sec. timer.
jpeg from camera, no post work.

@70mm, 320 ISO (ignore the black lantern to the left)
the tree is about 100' away.


@135mm, 320 ISO


@200mm, 320 ISO


crop of above.


@135mm, 320 ISO.


@200mm, 320 ISO. (note: small branches between camera and subject in above and below photos)


looking for PF
random shot, hand held, 640 ISO


PF does show up with very bright back-lighting, but I didn't see much otherwise.

I was very pleased with the results, and plan to test this lens more at 135mm, against my M135/3.5.
The little M is a favorite so far.
Some Tamron lenses seem to have not tested well, but I also like the results from my Promaster (Tamron) 28-105mm f/4-5.6.

I'll be honest, I use Picasa and don't know how to save an exact 100% crop.
I can use the slider to view at 100%, and crop with the crop tool.
Here is a pretty heavy crop.


I'm not use to enlarging this amount, and identifying PF is pretty new to me also.
This limb shot, at 70mm, looks pretty clean to me.




I'll also be honest and say I haven't kept any notes, and not sure if I took these with a tripod, or handheld.

I haven't gotten down to fine tuning with my F 35/70 yet, but plan to soon.
This shot with the 01 prime.


And with the 35/70 at 70mm, and probably f/5.6, 400 ISO.
Un-touched jepeg from camera.


I love this little lens on the K5, and 01.

Promaster (Tamron) 28-105mm f/4-5.6. Pretty much the same as the FA version, as I understand it.
Promaster 28-105mm f/4.0-5.6 Lens Reviews - Miscellaneous Lenses - Pentax Lens Review Database

One of my favorites, so far, on the Q with the Fotodiox adapter.
Following photos all at f/5.6.
Lens rested on top glass, side window of my truck.
jpeg from camera, very slight darkening on all in Picasa.

28mm f/5.6
ISO: 320
Exposure: 1/800 sec


105mm f/5.6
ISO: 320
Exposure: 1/500 sec


crop of above photo.


105mm f/5.6
ISO: 320
Exposure: 1/640 sec


105mm f/5.6
ISO: 200
Exposure: 1/400 sec


I'll try to add more, now that I half way know what I'm doing. :)

I'll add my thanks as well, even though my Q has not arrived yet.
Seeing what this little wonder can do is amazing!
Credit where it's due too for contributing members posting trials and errors.
