FYI: It appears to me that...

Hi folks,

It appears to me that stacking two 1.4X teleconverters on a Sigma 300/2.8 lens works much, much better than using just a 2X teleconverter. I took about 20 shots of various things to see what I could see. The image below was one of those 20 shots. I used a Pentax K-3 + Pentax 1.4X HD AW + Tamron-F 1.4X Pz_AF + Sigma 300mm f2.8 lens. Next week I will try it with stacking two of the Pentax 1.4X HD AW teleconverters. Multiply the focal length and aperture that you see in the EXIF by 1.4 to get the correct readings.

I think I might be able to track a BIF with this rig.

Try it folks. you just might like it.
