|comment:||This lens was $320 when released in 1994--$100 cheaper than the 24-85 which was released a year earlier and slightly more than the 28-85 RS. This definitely looks and feels like a premium lens, though the rounded 90's styling is dated. This lens is larger than the 24-50, 24-85 and 24-105 zooms but smaller than the 28-85, 28-135, and original 35-105 zooms. "JAPAN"|
I purchased a fourth excellent copy with original hood from a large eBay seller. The third clean copy came without caps or hood and claimed to be untested, which probably meant tested and found poor. My second copy was purchased 2 years after the first copy. This fourth copy is much sharper than the previous copies.
The 28-105 RS has the same optics as the non-RS and Xi versions. The non-RS also has curved aperture blades, but those on RS version do seem to form a slightly smoother aperture shape.
It has more contrast than the 28-135. Overall it performs similarly to the 24-85, 24-105, and 100-300 APO zooms. The 24-85 lens focuses closer than the 28-105 lens despite both being listed with a 500 mm MFD. The original AF series 28-135 and 35-105 zooms might be more reliable for sharpness.
It has less distortion at 35 mm than the DT 35 SAM but more distortion than the 24-85. It doesn't seem to have mechanical issues like the later clutched focus lenses.
Flat back plastic hood looks and feels cheaper than shinier black plastic hood on the non-RS version. The hood is deeper than the similar 24-85 hood, but both use the same 3-lobed bayonet mount and are mechanically interchangeable.
