Originally posted by imtheguy Ok, so one firmware update and a test bottle of juice convinces me this TC is for real.
The left pic is K-3 + da*300 + 1.4xTC at f8 (the camera automatically ups the displayed aperture by one stop when the TC is mounted) shown at 70%
The middle pic is K-3 + da*300 at f8 shown at 100%
The right side pic is K-3 + da*300 at f5.6 shown at 100%
No adjustments, no worries about in-camera settings, just 3 shots of each to make sure they did not vary and they did not.
With the originals I find a very slight advantage to the left side shot with the TC. Very pleasing that looks slightly better (to me anyhow) sans TC. I am a happy camper with this purchase so far....now tomorrow its time for the real test and find some birds!

A few questions answered...it works pretty much seamlessly, it works on third party lenses, it allows you to use selective focus, works seamlessly on either SDM of screw drive, ... and it tells the exif file what it's doing... I didn't have a lot of time with it today... but I got out late.
On the DA * 60-250 (SDM)
On the Tamron 90 Macro (screw drive).
Thanks a bunch to you two !
We are finally getting some real "tests" (I hate saying "tests", but for lack of a better word ...).
So .... honestly: do you think there is some truth into admitting that this TC is well worth its hefty price?
@ imtheguy ... In terms of IQ, if I were to compare the shots taken with the DA*300/4 with/without the TC, what is your "rating" from your posted images ?
I am asking many questions because I am on the verge of hitting the buy button at Henry's, which will take me back $600 vs. near $6000 for a Sigma 500/4.5 -- I know, I am comparing apple to oranges here but better have good IQ at 420mm than busting the retirement funds.
I also see that the cropped images at 70% and 100% are quite good indeed or is it me trying to justify the IQ of the TC?
Cheers!
