Morning
does anyone have this lens
I am still searching for a "long" macro to shoot Dragonflies and Butterflies and have read a few good review of this lens
although one review said this:
"An optically great lens will not show its strength if it delivers an out of focus image. Unfortunately, I had a lot of mis-autofocused results from this lens - far more than could have been my fault. Sigma's internal HSM(Hypersonic Motor) autofocusing is very nice - quiet with FTM (Full Time Manual) focusing. But it is only moderately fast and it showed inconsistent accuracy in both one-shot and AI Servo AF modes. The Sigma 150 focuses even more slowly in low light. A 3-position focus limiter switch (seen above) helps with the speed issue - it prevents long distance hunting. On a macro lens, focusing from very close to infinity or reverse takes some time even on the fastest focusing lens. You can limit the Sigma 150's focus distance range to between 15" and 20" (.38m and .52m), 20" (.52m) and infinity - or the full range can be allowed"
"This is far from the slowest or most-inconsistent autofocusing lens I've used but definitely is not the best in this regard. Fortunately, most macro photography is done using manual focusing which makes any autofocus inconsistencies and speeds irrelevant. This is a really nice 150mm telephoto lens that could be even better for general purpose and sports use if it had fast and accurate AF."
The only other "long" Macro I can find is the Nikon 200mm
Great to hear a few of your views
