Tamron has announced a new pair of high quality image stabilized primes. The Tamron SP 35mm and 45mm mark the companies first venture into this category of lenses, providing competition to the incredibly popular Sigma Global Vision line. Tamron are known for their affordably priced, feature rich zoom lenses. The 17-50mm f/2.8 VC (Vibration Control) and 24-70mm f/2.8 VC are popular budget choice lenses for video shooters using APS-C and full frame cameras respectively. The latter a particularly interesting number as there is no other direct replacement for it (both Canon, Nikon and Sigma standard zoom lenses offer Image Stabilization or a fast f/2.8 aperture, not both). Whilst Tamron has offered much in certain departments it has lacked in others. Build quality has always been a downside when comparing to other lenses, and short focus throws make them tough for video shooters. The new SP (Super Performance) prime pair look to make some changes, offering up a first for Tamron in the high quality fixed focal length sector (ignoring their current macro lenses). Looking at the spec of the two in detail: The Tamron SP 35mm f/1.8 Di VC USD and Tamron SP 45mm f/1.8 Di VC USD are full frame lenses (signified by Di in their titles) so compatible on both photography full frame and APS-C/Super35mm sensor formats, VC as above standards for Vibration Control (Tamrons version of Image Stabilization). USD refers to the Ultrasonic Silent Drive motor system that’ll please mostly stills shooters but for us video guys it means that lenses offer full time manual focus (even in AF mode) plus the potential to work with video auto focus systems like Canons Dual Pixel AF. One Low Dispersion element, one extra Low Dispersion element, and two aspherical elements help to control a variety of aberrations and distortions for consistent and even illumination and sharpness, as well as reduced color fringing, and eBAND and BBAR coatings work to suppress flare and ghosting for increased contrast and color fidelity. You’d be please to know that both prime lenses feature a moisture-resistant construction, complete with rubber seal on the back on the lens and fluorine coated front element. Here are the specifications for both lenses: Tamron SP 45mm f/1.8 Di VC USD Focal Length: Fixed 45mm Maximum Aperture: f/1.8 Minimum Aperture: f/16 Format Compatibility: 35mm/APS-C Angle of View: 52° 21′ Minimum Object Distance: 0.29m (11.4 in) Maximum Reproduction Ratio 1:3.4 Elements/Groups: 10/8 Aperture Diaphragm: 9 Rounded blades Image Stabilization: Yes Autofocus: Ultra Silent Drive Filter Thread Front: 67 mm Dimensions (DxL) Approx: 3.17 x 3.60″ (80.4 x 91.4 mm) Weight: 1.2 lb (544.31 g) Tamron SP 35mm f/1.8 Di VC USD Focal Length: Fixed 35mm Maximum Aperture: f/1.8 Minimum Aperture: f/16 Format Compatibility: 35mm/APS-C Angle of View: 63° 26′ Minimum Object Distance: 0.2m (7.9 in) Maximum Reproduction Ratio 1:2.5 Elements/Groups: 10/9 Aperture Diaphragm: 9 Rounded blades Image Stabilization: Yes Autofocus: Ultra Silent Drive Filter Thread Front: 67 mm Dimensions (DxL) Approx: 3.17 x 3.20″ (80.4 x 81.3 mm) Weight: 16.9 oz (479.12 g) It’s clear by the aesthetic design of these two lenses that Tamron has gone after the same target audience as Sigma with their Global Vision Line (particularly the Art series primes). This is great news for budget video shooters as there are now even more options in this department. The fact that these are newly designed Super Performance primes hopefully means that these are a grade or two above Tamrons other lines in terms of build quality. Sigma did an exceptional job with stating the premium status of their Global Vision Line, this could be a similar move from Tamron but in an even more cost effective price bracket. Coming in at around $600 each, these lenses come in competitively priced yet offering important features like a fast f/1.8 aperture, Vibration Control and weather sealing. via/ CanonRumorsRead more

We already reported about the much-anticipated Sigma 18-35mm f/1.8 DC HSM Art lens (click here), the first modern auto-focus zoom lens with an f-stop of 1.8. Because of its incomparable speed we were ready for a relatively high price tag, even though it’s a Sigma lens. But it turns out that Sigma decided to surprise us – it will be available in July and will cost only $799 (you can already preorder it at B&H by clicking here).Read more

Sigma just announced one of the fastest zoom lenses for DSLRs that we have ever seen – the 18-35mm f/1.8 DC HSM Art lens for APS-C sensor DSLRs. It’s the world’s first constant f/1.8 zoom lens. A typical speed for high quality zoom lenses is f/2.8, so 1.8 is a big step up from that (don’t forget, after all aperture is an exponental value, meaning that every stop more gives you twice the amount of light. The only fast zoom lens that comes pretty close is the Olympus 14-35mm f/2.0, but that’s a Four Thirds model. It makes a HUGE difference to have faster lenses, even if it’s only a one or two stops more. And so far, one of the biggest problems of zoom lenses was the fact that they were nowhere near as fast as fast primes (that typically come in at f/1.4). Sigma’s new f/1.8 zoom is only half a stop away from that – pretty impressive. UPDATE, June 14: Pricing is out and it is spectacularly low for such a fast zoom lens – $799! It is available to preorder from B&H now. Available July 31.Read more
