Very Nice !!!

Has anyone with this fine lens tried a teleconverter shot as well? I'd love to see what F2.8 looks like when extended via the 1.4 or 2x TC. Thanks!

Thank you for all the replies, sample pics and answers. Those are some really, really amazing pics! I wasn't quite sold on this lens due to the "small" difference in focal length between the kit lens and/or the 50-200 mm zoom lens but after seeing the samples, I am truly amazed.

I recently had a very good opportunity to purchase the 77 limited at a very good price but decided to play the waiting game on the new line up of lenses .... I am glad I did. I may just have to pick up Pentax's new zoom now !

Hi Folks..
Today was really the first day I had to take out my camera K10D with the new 50-135 lens...To be honest, I was not very happy happy with it...Now, I am not blaming the lens, but my lack of experience..This lens on my K100D super works very well and is very sharp..Not so on my K10D..Some pics came out underexposed and other over exposed...The only decent shots came in complete green mode...Here are some of the better pics and these are not that good...I put them here so that someone that knows what they are doing can look at the exif data and see if there is anything obviously wrong....I will also post two more pics with a severely oever exposed pic...I took all this a little while ago...

Here are some characters from today..

jgredline · 11-19-2007, 06:01 PM

Any ideas?

jgredline · 11-19-2007, 06:14 PM

Here is one more of my son..I think this one looks pretty good...
I wish I knew why.

What mode are you in? Green/Auto mode? Av? Tv? How much do you know about exposure? (how f-stop/ISO/shutter speeds interact)
Aside from that one obviously overexposed shot, they look ok. Not great, but they look ok. Looks like some weird JPG/downsizing/compression artifacts though.

The fact that (1)you only got good shots in AUTO and (2)You can't seem to diagnose what you think is wrong with the pictures, I suggest you slow down and learn the basics of photography. In an earlier post, you confessed to not knowing what stops were. I think you would benefit greatly if you stop buying high-end expensive gear and learn some basics. Do you really own BOTH DA*s, a 77mm Limited, a Nikon D200, TWO Pentax bodies, and a few other lenses??????? WOW!

Bryan Peterson's Understanding Exposure is a great book to read.

Yes I do and a D40...and yes, I need to understand how exposer works...I will look for that book.
Thanks

Regarding the overexposed shot and the similar one that isn't overexposed, the overexposed shot is more than two stops brighter than the properly exposed one. How did you meter these two shots? The bright one is 1/250s, f/3.5 @ISO100 and the other one is 1/500s, f/8 @ISO200. Either you're doing something wrong or the camera is faulty.

Again, What mode was the mode dial on?

Ever since I updated the firmware to 1.3 the camera has been funny..In green mode it works well, but for the life of me. I can't get it to work in any other setting...Likely I am doing something wrong..

jgredline · 11-19-2007, 08:00 PM

Here is what I was using today.

This Tamron 18-250mm lens is amazing..

Here are a few of the lenses I have in my room..The rest of my equipment is in the closet downstairs and in my car..

Can you please explain?

The metering system isn't omniscient. It tries to guess how to best pick one single exposure value for the whole scene. If it (due to meter zone alignment or other arcane workings of the matrix-metering mode, or if you're using spot metering and point right ad it) picks something very dark as the basis for that exposure, the rest of the scene will be overexposed.

Generally matrix-metering is very smart, but I often prefer predictable over smart and go with center-weighted instead -- dialing in my own EV compensation where appropriate.
