I tried it with the 77mm Limited and the results were good, more than usable. However, not as good as without the TC (as expected). Actually it made for a nice, but slow compact telephoto. I ended up getting an FA 135/2.8 so I don't have much need for that TC-lens combo anymore. Tyler On Mon,

I tested the DA70 on the Pentax-A Rear Converter 2x-S. The results were not particularly great, a good deal of chromatic aberration and red-fringing developed. I don't know how different the design of the 1.7x converter is. Godfrey On Jun 23, 2008, at 3:04 AM, Charles Wilson wrote: Has

Well the DA 40mm ltd is essentially the same formula as the M 40mm, and the same caveat that Boris give about the DA applies. The DA 70 has no aperture ring, (Ok, I'll say it for you/ Well Duh!), and it has limited usefulness on most Pentax Film bodies, at least the ones I'm interested
