"Trying to choose..."


Spartanburg, US
          

I am replacing my short range telephoto lens that I use with the D7000 and D5100. I've decided to focus on the Sigma rather than the Tamron after reading reviews and Nikonian articles. {I can't afford the Nikon 24-70]. I'm hoping the forum can help me decide.

Is the Sigma 17-70mm f/2.8-4 DC Macro OS (Optical Stabilizer) HSM AutoFocus Super Wide Angle Zoom Lens for Nikon compatible with the Nikon D5100? How about the Sigma17-50mm F2.8 EX DC (OS)* HSM?

If I am correct in my thinking, the HSM means that the lens has its own motor and both lenses are compatible with the D5100. Do any of you

I'm trying to decide between the two, so any input on your experience with either of these lenses and the D5100 would be appreciated.

Hi Lynn,

You are right.
HSM stands for Hyper Sonic Motor, Sigma's version of Silent Wave Motor.
Therefore bothe lenses support AF when used on the D5100.

The 17-50mm f/2.8-4 DC Macro OS HSM is a variable aperture zoom.
The 17-50mm f/2.8 EX DC OS HSM is a constant aperture zoom. It is optically superior and has a better build quality.

Best Regards,
Marty

Thank you. I'd heard that the f/2.8-4 has just been redesigned and the optics have improved greatly.

I originally wanted the 2.8 but was looking at the other because it was less expensive, improved optics, and weighed less and might balance better on the D5100. However, both lenses weigh the same!

Every Sigma HSM lens has an internal motor, so both of these will AF on your D5100.

However, the reverse is not always true. Some Sigma lenses that do NOT have the HSM moniker DO have internal focus motors! Sigma HSM is like Nikon's ring-motor AFS, the higher-end ones. Unlike Nikon, which applies AFS to both ring motor lenses as well as geared micro-motor models, Sigma chooses to simply not mention micro-motor in the abbreviations, choosing to state that the model "has an internal focus motor."

I've never used either of these, but I think I've seen more favorable comments about the 17-70. This one is one of Sigma's new Contemporary series lenses; in common with their Art and Sports, these are their latest designs that are field-upgradeable via the USB dock, and which can be switched to other mounts by Sigma (for a price). Given what I know about the two (and what I don't), I'd opt for the 17-70 between these two.

I've got some questions about that "updating" in the Sigma, but I think I will post that over under the lens section.

I wonder if they will do the same sort of upgrade to the 17-50.

Thanks for the input!

They'll only do it when they redesign the lens. The configurability of these new series lenses mandates a fairly different way of designing the internals. They can't just plop the old stuff into the new process. I don't have any inside knowledge, but I'd be surprised if they didn't have to do a pretty extensive retooling of the plant to do this kind of thing.
