I was in a camera shop this morning and noticed a Sigma 50-500 f4-6.3 lens……I so wanted that lens…the only thing that stopped me from buying it on impulse was the fact it was for a Nikon and not my Minolta. Had it been a Minolta mount then I would be showing off photos now instead of asking the question…..are they a good lens. For the type of shots I prefer to take the range on this lens would suit me just fine. Does anyone on this site have one or tried one to give some feedback………ooooooohhhhhhhh….. I so want that lens
That's the Sigma Bigma!
By reputation, the image quality from the bigma is pretty good (which is impressive for a lens with such a huge range).
The downside is that it weighs a lot.
Interesting design with the handle though :) How much was it selling for?
I think I read somewhere on this site some time ago by a Bigma owner that is quite a good lens. Again, a heavy lens, but very good image quality. And it is made for the Minolta/Sony mount.
And it is made for the Minolta/Sony mount.
Yep, though without HSM. All the other mounts, except I think Pentax, get HSM. :(
can you please explain what HSM is, and why do some get it and others don't........(I'm starting to feel inferior to other brands)
Hyper Sonic Motor, I think. Basically means the zoom zooms more quietly. Not a big deal as far as I know
does minolta not get HSM because the autofocus is controlled by the body, not the lens?
or have I got that wrong?
That is my understanding. The other camera makers already have a need for a motor in the lens, so they get the HSM, makes a good marketing tool.
Minolta/Sony already have the motor built into the body, so not only no HSM, no motor at all.
Some misunderstandings here.
HSM is to do with focus, not zoom. HSM is quiet and mostly quick. AF-S is the Nikon equivalent. Canon have the same deal.
Minolta lenses have no motors, except the very newest SSM ones. Nikon lenses only have a motor built in when they say AF-S on the lens, as all their new lenses do, otherwise the camera itself drives the lens, as in Minolta, with a screw.
HSM and AF-S lenses lenses are often much nicer and faster to focus than 'ordinary' lenses, they also allow instant manual override, meaning no switches at all, which is great. So it is actually a big deal if you have the option, but as you don't really have the option with Minolta, don't worry about it. You won't miss it on a slow lens like the 50-500.
The 50-500 is actually pretty good, even better for Minolta because of the AS system. However, the animals you shoot need to be chilling, becuase the lens is too dark and slow and cumbersome for predictive focus and whatnot.
Consider the 500/8 instead, for it is much lighter. But you have to mind the bokeh with that one.
