Nikon's not the only one having fun in the pre-Photokina run up. We're hearing that Sigma, Tamron, and Sony have also been announcing some new lenses, and we figured we should probably drop in and mention a thought or two on them for y'all.
People might argue with me, but for my money the coolest of the bunch is Tamron announcing the development of a 15-30mm f2.8 constant full-frame ultra-wide zoom... with image stabilization! Yup, joining the 24-70 and 70-200 will be a stabilized full-frame zoom on the wide end, completing Tamron's own holy trinity of lenses. Holier, really, once you factor in that theirs are all stabilized, and not just the 70-200. It'll be noted as model A012, and have 18 elements in 13 groups including a so-exotic-I-think-they-made-it-up XGM (eXpanded Glass Moulded aspherical) element. It'll also sport update coatings (including being Tamron's first fluorite coated lens) and a special copy of Silky Pix for working with images shot using the new SP line of Tamron lenses. Though, when it's coming and for how much are anyone's guess.

After the Tamron, second most interesting has to be Sigma, who decided that announcing just one lens of a type was for chumps and actually announced two completely different 150-600mm f5-6.3 lenses at the same time. One is in their "Sport" line and is a pro caliber lens with heavier build and superb quality, the other is in their "Contemporary" line and offers a smaller, lighter lens in exchange for some of the quality and cost.
The Sport 150-600mm
The "Contemporary" 150-600mm
Both versions offer OS "optical stabilization," which is good because on zooms this big you'll need that unless you travel everywhere with a heavy-duty tripod at hand. The Sport model is splash proof and features 24 elements in 16 groups and takes a jaw-dropping 105mm filter on front. Oh yeah, and 2 of those lenses are FLD and 2 are SLD, so, dispersion ought to be pretty well addressed. The Contemporary model steps back ever so slightly from the ledge, topping out at 20 elements in 14 groups (only 1 FLD, but still 3 SLD), and a 95mm filter thread that doesn't quite manage to be reasonable either. Both lenses are solidly TBA in both the arrival and price categories, so, keep an eye out for more news as it comes.

If you prefer to get your super-telephoto lengths through more conventional means, they've also announced they're making a new 1.4x and 2.0x teleconverter, both of which are splash proof and autofocus up to f8 (so, yanno, not on the leviathans pictured above). If you're guessing that TBA is the trend here too, you're pretty good at this guessing thing then.
And, to close us out we have Sony, who's turning in the gnarliest looking lens I've seen in a while:
Those of you who this lens is meant for will know already, but those spikey rings everywhere aren't just a defense system or a way of attracting mates. The FE PZ 28-135mm F4 G OSS here is born to be a cinema lens, and all those are the tracks for easier use of cinematic zoom and focus rings, knobs, and other contraptions. Now, the FE designation lets us know this is an E-mount lens of the full-frame variety, meaning it's for use on the A7 family (A7,A7r,A7s) of mirrorless cameras. Care has been put into it to minimize breathing while focusing, and it'll maintain its focus point while zooming like a proper cinema lens. The three rings control the zoom, focus, and iris. All-in-all, a solid show of Sony's commitment to making the A7 family true stand-outs in the hot 4k video space. Availability I don't know, but the price for this bad boy will be around $2500 once we start getting them.
