Got it cheap.
When the package arrive, I was intending to use it with my OM-D... with the x2 crop, I am able to push the range up to a maximum of 410mm equivalent to 35mm film (which is good for birding). So I try... I would not say that I fail miserably... because I took this lens to Australia and it was a pretty good lens... except for very very bad zoom creep.
A few shots of the lens...
Talking about sharpness... this lens is a beauty... extremely sharp.
When I am back in Singapore, I adapt the lens to my Canon 7D... and was amazed at the lens' capability.
I am able to capture with decent sharpness of the small and fast sunbird in my front yard. I had problem to capture this bird with my more modern EF70-200mm f4L before, the AF simply couldn't follow the bird at a very contrasty environment.
Anyway the lens is not really very heavy and it is so much smaller than my f4L, so carrying it around is not a chore.
For that type of money, this lens is a pleasant alternative for modern lenses. If you happen to find one in ebay... do not hesitate. Grab it! And have fun.
