Stack two TCs on Sigma 300/2.8 (6 imgs)
5 months ago

Hi folks,

I was testing the combo so I figured I might as well show it to you folks also.

Pentax K-3 + two (2) Pentax 1.4X HD AW teleconverters + Sigma 300mm f2.8. Multiply the aperture and focal length in the EXIF by 1.4X for proper reading. Note: Judging from a previous test I did with stacking a Tamron-F 1.4X Pz_AF with a Pentax 1.4X HD AW I don't think there is much difference.

I shot these handheld. The crops are 100%.

Subject distance about 100 feet.

100% crop

Subject distance about 70 feet.

100% crop

Subject distance about 40 feet.

100% crop

Cheers.

Ron
