Sorry, could this be because the street lights were shot through the window, causing the ring highlight?

Tamron 28-75/2.8

To be perfectly honest, I bought the lens solely for this event and have hardly used at all since then. I have very little use for it and often have considered selling it. The problem is that it is a fine lens, and that it constitutes one-half of my zoom/af lenses (the other being the Tamron 17-50/2.8). Those rare times I need zoom/af and something over 50mm....this is all I have.

Plus the fact that I have yet to see anyone here who sold this lens and didn't later regret having done so.

These images are great. Love the colors and contrasts. (I'd love to see the first one in color.) I appreciate your honesty. I hope I find it more useful that you do though!

I was actually pretty surpirsed at how quick the AF was and I thought the IQ was actually pretty good. Obviously you lose a stop of light and some IQ in exchange for an range of around 40-105. In the end I'm not sure if you'd be better off cropping w/o the teleconverter, but for what it's worth it worked a lot better than I thought it would.

Well of course I'd have no idea but I thought I'd quote you so maybe someone who would know might see the question....

Cool shot! : )

Thanks

I just had to put an end to the story...
Got the lens on Monday, played with it at home a bit on Tuesday, and then today baptized it by fire today by taking it to school, one of the more challenging places for me historically. I do the yearbook and we needed more shots of 5th grade kids and the special needs classes. Took only the new lens on my KX, and snapped a bunch in two special needs classrooms, and a bunch more in the lunchroom of the 5th graders at lunch.

Oh my goodness! I could not be happier! It performed perfectly with the Kx! There were some misses sometimes with unintended DOF, but otherwise I could not be happier. I used P mode and flash most of the time to give myself better odds for sharper focus what with the moving subject matter and no time for adjustments. I just can't say how happy I am with this thing. The color, sharpness, contrast, and even the range worked perfectly for me. I've always wanted a good camera, and now with this lens at 47 I am finally getting the pics I've always wanted. I can't believe it!

Sorry to blather on, but this is just a dream come true for me after years of frustration. To all of you who assured me, you were SO RIGHT! I wish I could post some examples, but they are other people's children and I can't. But here's a heavily cropped example just to show how great the color and clarity are...

All is now forgiven Pentax forum and all Pentax forums and all Pentax info on the internet. : )

Congratulations--glad you're so pleased. The Tamron 28-75/2.8 is a god-send for those looking for a kit lens replacement, with a fast constant aperture, willing to forego a bit on the wide end to get a bit more length on the long end, and all at a very affordable price. It's a super lens.

cyy47 · 03-03-2010, 12:44 PM

Congrats! It is indeed a great people lens without the hefty weight or price tag. Glad you enjoyed it so much and hope more great pics for years to come.

bimjo · 03-03-2010, 07:10 PM

Congrats! Looks like a keeper to me.

Igilligan · 03-03-2010, 07:19 PM

Great to hear a success story. I have always loved my tammy on my k100/k20... but on the Kx it is crazy good!

efg · 03-04-2010, 12:42 PM

Thanks all.

Incredible detail in those shots Mike. Be really hard to give up that kind of image quality if you didn't absolutely need to.

I'm loaded with Takumars, so it isn't image quality that I would give up. I have this lens for when I need zoom and autofocus capabilities.....which ain't that often.

Ok, but you aren't giving up a whole lot in comparison by using this lens in those situations.

If I could afford it I'd have a whole bag of primes myself.
