New lenses from Sigma from the PMA!<\/p>\n
1) Sigma 85mm F1.4 EX DG HSM, 85cm MFD, 1:8.6x maximum magnification<\/p>\n
On the Sony side there is the Sony Carl Zeiss Planar T* 85mm F1.4, with 85cm MFD and 1:7.6x<\/b> maximum magnification. The Zeiss has better magnification because it is not an internal focus lens – the downside is that it extends out has does not have SSM.<\/p>\n
2) Sigma 8-16mm F4.5-5.6 DC HSM, 24cm MFD, 1:7.8x maximum magnification<\/p>\n
Which is the APS-C version of this:
\nSigma 12-24mm F4.5-5.6 EX DG, 28cm MFD, 1:7.1x maximum magnification<\/p>\n
I’ll just say that 12mm on 24 megapixel full-frame is sweeter. However it is nice of Sigma to give an APS-C version – let’s hope they also upgraded the performance wide open. <\/p>\n
3) Sigma 70-200mm F2.8 APO EX DG OS HSM, 140cm MFD, 1:8x maximum magnification<\/p>\n
Okay, a downgrade in minimum focus distance, which was a strength of the previous version:
\nSigma 70-200mm F2.8 EX DG Macro HSM, 100cm<\/b> MFD, 1:3.5x<\/b> maximum magnification<\/p>\n
Unless they upgrade the optical performance especially at 200mm F2.8 at close focus, I don’t see how the new version is worth it for a Sony or Pentax dSLR.<\/p>\n
4) Sigma 17-50mm F2.8 EX DC OS HSM, 28cm MFD, 1:5x maximum magnification<\/p>\n
Another downgrade in some ways compared to the previous version:
\nSigma 18-50mm F2.8 EX DC, 20cm<\/b> MFD, 1:2.7x<\/b> maximum magnification<\/p>\n
The unique selling point of the old Sigma was the close focus capability even at wide angle. Now it’s just a Tamron copycat, while being slightly weaker.<\/p>\n
Interestingly, here’s the Tamron lineup:
\nTamron 17-50mm F2.8 VC DiII, 29cm MFD, 1:4.8x maximum magnification (only for Canon and Nikon)
\nTamron 17-50mm F2.8 DiII, 27cm MFD, 1:4.5x maximum magnification<\/p>\n
5) Sigma 50-500mm F4.5-6.3 APO DG OS HSM, 50-180cm<\/b> MFD, 1:3.1x<\/b> maximum magnification<\/p>\n
Finally, a great upgrade to the previous version, which was prone to gear stripping:
\nSigma 50-500mm F4.5-6.3 APO EX DG, 100-300mm MFD, 1:5.2x maximum magnification<\/p>\n
