Today, Tamron is announcing their plans to release two new lenses for full-frame DSLRs in mid-2019.
35-150mm f/2.8-4 Di VC OSD
This wide-to-telephoto 35-150mm zoom lens covers most of the portraiture focal range, all with a decent f/2.8-4 variable aperture. Inside the lens features low dispersion glass and aspherical elements to correct for optical aberrations. This lens has a minimum focusing distance of 17.7 inches across the range.
As the full name points to, this zoom lens is made for full-frame or crop-sensor camera bodies (Di), has vibration compensation (VC), and utilizes Tamron's Optimized Silent Drive (OSD). In addition, Tamron mentions that the 35-150mm uses a Dual Micro-Processing Unit for improving autofocus performance and the vibration compensation.
SP 35mm f/1.4 Di USD
Tamron did not disclose much detail about the upcoming 35mm f/1.4, other than to say it will feature "high-speed, high-precision autofocus functionality" and "various other features." I suppose at this point, what new is there to say when it comes to one of the more saturated lens choices on the market.
At least from the naming, we know that this 35mm will be part of Tamron's Super Performance (SP) series of lenses. It will also work for full-frame and APS-C DSLR cameras, and will feature an Ultrasonic Silent Drive (USD) for autofocusing.
Both the 35-150mm f/2.8-4 Di VC OSD and SP 35mm f/1.4 Di USD lenses are expected to launch in the middle of 2019, with pricing still to be determined. If you're attending CP+ or WPPI in the coming weeks, Tamron will have these on display for a closer look.
