Look what I found on DPreview...
Chicago Air Show w/ DA 55-300 + Kenko 1.5x TC [6 imgs]: Pentax SLR Talk Forum: Digital Photography Review
I may have to get myself one of these.

Another TC question...
Has anybody tried to use a TC for distance shots with a 1:1 f2.8 macro (ie--Tamron 90, DFA 100, Sigma 105)?

Thanks!

i saw the post too and it looked pretty interesting ... however it did mention that

The majority of the shots were taken at 300 x 1.5 = 450mm, with subsequent cropping, contrast increase and sharpening in Picasa.

so it's hard to judge the initial quality of the photos before all the PP and what toll the TC did on the images.

I'd be interested in seeing the original images, as well. If there's too much PP involved, then I'm not sure that I'd want to go that route. As much as it may hurt the wallet, perhaps the fast 2.8 telezoom + TC might be the better combo...sigh.

I have the DA 55-300, the Kenko 1.5X and the Sigma 105mm. It works somewhat in good light with 55-300 but works very well on the 105mm due to the f2.8. I ended up replacing my Viv series 1 due to a aperture blade stuck open and tele focusing and am just as happy with the Sigma, maybe more so. The Sigma isn't the piece of art the Series 1 was but wow otherwise. I'll be honest, I would have gotten the Tamron 1.4x if somebody had them in stock but I got impatient.

Even if the TC doesn't work that well on the 55-300, what I'm thinking is that I could use the TC on the tele prime. I plan on eventually getting a second body, so when I go out to shoot at a zoo or wildlife, I'd have the 55-300 on one body for shots in good light and the prime+TC on the other for lower light shots.

I've got some overtime at work coming up, so I'll have some extra money to play with. In this case, I'd sell the A100/4 macro and replace it with the 2.8 macro.

Heather, I have not tried the Kenko 1.5 on the 55-300 (maybe I will later today) but in general the Kenko seems to hunt more in AF than the Tamron 1.4 tho the IQ is equivalent. Another option is the Promaster 1.7, about which Hinman has posted. I have used this on the 55-300 and function/IQ are almost as good as the Tamron 1.4. Of course, neither the Kenko nor the Promaster do USM...............

The Kenko I saw on Himan's site was the 2x marcro. It and the Promaster 1.7x are interesting though.

Edit: here is a thread on PF by Hinman also: https://www.pentaxforums.com/forums/pentax-slr-lens-discussion/34418-promaster-1-7x-af-tc.html

After looking at some of Hin's pics, that Promaster 1.7x looks good. It's actually cheaper than the Kenko, too.
