Here are a few photo from the Sigma 100-300 F4 and 1.4x teleconvertor...
EXCEPT the first one what was with the Yashica Yashinon 60mm F2.8 1:1 Macro M42
lens i picked up in Arkansas on a recent vacation for $15, the lens is excellent for
its build quality, very smooth operation, the aperture blades and in beautiful
condition and the glass is spotless (after i cleaned it) the only problem is that
when extended and tilted up or down there is something inside that slide back
and forth in the barrel, after a number of test i can tell you its not affecting the
aperture or optical performance
Yes this was taken with a manual focus 60mm F2.8, only slightly cropped for better composition
The rest are of course with my typical setup Sigma 100-300 + 1.4x
