Today, Broncolor is making a new addition to their super high end lighting in the form of the Siros L. They’re billing it as a light for photographer who want no compromises.

For starters, it’s boasting lithium ion tech, ECTC tech, and can produce 440 full power flashes on a single charge. Beyond that, it’s also got a flash duration of up to 1/19,000 and promises consistent color temperature output through the entire range of its power.

More details from the press release are after the jump.

Siros L is a true Broncolor unit, produced for ambitious professional photographers who do not want to make any compromises. Most modern lithium ion technology paired with the ECTC technology known from our high-end power packs makes it possible: 440 flashes with full power, flash duration up to 1/19,00 (t 0.5) and, of course, guaranteed constant color temperature over the entire control range.

Siros L is an absolute mobile unit, either outdoor or on location and corresponds with the photographer’s need for more mobility. However, Siros L can also be optimally used as an additional unit with a Broncolor studio equipment. The 25 watt LED modules offer a bright modeling light with a color temperature of 3000 K. The quality is comparable with the modeling light of our AC powered units.

From the sales launch, Siros L will be available in two power levels, 400 joules and 800 joules. The 400 J version with the smaller dimensions and weight is the option for photographers who are often on the move. The 800 J version is made for photographers who refuse to compromise also with regard to power.

The New Nikon P1000 Has a 125x Optical Zoom with a Laughable 1/2.3 inch Sensor for $999.95

Today, for some odd reason, the Nikon P1000 point and shoot camera is being announced. Odd, you ask? The fact that it is a point and shoot isn’t such a big issue at all; but the fact that it’s a superzoom camera being marketed as one with a 125x optical zoom is what’s insane. Kudos to Nikon for being able to do something like this; but then you read the fine print (or in this case, print that’s not even in the press release) and see the bait and switch–this Nikkor lens is having its potential wasted by being placed in front of a 1/2.3 inch sensor.
