Sony is going wide with its newest lenses for full-frame E-mount cameras.

The f/2.8 G Master 16-35mm and f/4.0 12-24mm lenses represent two approaches in the wide-angle zoom category.

While both are intended for Sony’s full-frame A7 and A9 mirrorless cameras, they also can be mounted to its bodies with APS-C sensors. Factoring in the 1.5X crop, the 16-35mm becomes a 24-52.5mm, while the 12-24mm becomes an 18-36mm.

Photographers who shoot with Sony’s E-mount mirrorless cameras have been limited to a handful of Sony-branded telephoto lenses.

The addition of the Sony FE f/4.5-5.6 100-400mm GM OSS is the third pro-level telephoto zoom for the E mount. This lens also is Sony’s fifth lens in its premium G Master series.

Sony’s E-mount cameras seem to have gotten most of the attention this year, with its A-mount family standing on the sidelines.

Unknown to most, Sony was working behind the scenes and has announced the full-frame A99 II.

Priced at US$3,199, the A99 II ups the resolution with a 42.4-MP backside-illuminated full-frame CMOS sensor – a big increase in resolution from the 24.3-MP CMOS sensor of the original model. The A99 II omits the low-pass filter.

When Leica announced its full-frame mirrorless SL system last year, it also promised two more lenses: a 90-280mm zoom and a f/1.4 50mm lens.

The APO-Vario-Elmarit-SL f/2.8-4.0 90-280mm is now available for purchase.

While the lens is intended for the full-frame SL, it also can be used on APS-C L cameras, and the zoom range becomes 135-420mm.

There’s a lot to like about this lens, which was designed in Germany.

For those looking for a high-end ultrawide-angle lens, TH Swiss AG, a new photography company, has announced a fast f/2.4 15mm lens.

The lens is being released in three mounts: Canon EOS, Nikon F and Pentax K. The Irix 15mm is intended for use on full-frame digital cameras, although it also can be used with APS-C bodies when the crop factor must be taken into account (24mm for Canon EOS and 22.5mm for Nikon and Pentax).
