Telekonverter, alternativs for k-1?

Hildalill · 06-25-2016, 11:07 AM

Hi, I will soon get my K-1and I love to use my sigma 120-400 on the camera. I was thinking about the possibilities of a rear tele konverter. The 1,4x pentax is a da- but seems to work with vingetting. Is there other and bryter options?

These 2(ish) TCs are some of the more common 1.4x TCs that cover the FF image circle.

I'm using the Vivitar version on my 135/400mm sigma, The Tamron is similar(the same?).

It works fine and does a great job on the DA55/300 as well.

Will be testing a Sigma AF 1.4x when it arrives soon.

Are these teleconverters currently available new, or only used?

Only used I believe.
