Clouds and Sun Rays with Pentax K-x White

clouds and Sun Rays with Pentax K-x WhiteI was having a bad day in photos as I have mounted a Tamron 75-250mm f/3.8-4.5 adaptall-2 (104a), a cheapo zoom, and I naively mounted the Tamron 2x TC adaptall-2 (01f) on it while hiking in the weekend. The combo is an absolute DOG in shooting birds due to slow speed, lost of light with little contrast, and CA is apparent everywhere.

I was supposed to try out the 2x cheapo 150-500mm zoom on birds and all birds were not close enough but rather way out in the sea. And the sunset with low clouds lured me to try sky shots instead. But the rig at hand was not matching for landscape shots. I should have dismounted the TC to shoot at 75mm to 135mm with the zoom. A big mistakes on my part as the scene is much more dramatic than I shot at. In some of the shooting, I changed to BW with Infrared filter in Pentax K-x to hide the CA/PF.

I noted the sunset with spectacular sun rays streaming through the low clouds in the stormy weekend weather. In keeping pace with my family, I only managed to take few shots and not having time for the proper setup. I shot all in the shortest focal length in 150mm.

Sometime, life presents me those precious moments that I am not prepared for. In hindsight, I should have brought in another lens and TC back home.


Notes
  • The zoom lens does fine to outstanding without TC. With the Tamron 01F 2x TC mounted, it is quite poor in CA/purple fringing especially in the long end.
  • The combo is pretty much hand-holdable but very difficult to get focus on moving objects. I changed from AF-A to AF-C to by-pass the catch-in focus and it is still difficult to handle as I can't have quickness and precision at the same time.
  • Contrast is poor in the combo, maybe something wrong with the 2x TC.
  • I should have tried Pentax-F 1.7x TC at another time

I think the photos came out fine, no need to beat yourself up on what equipment you took; it happens!
At least you had a camera around!
