Samsung Quattro Refrigerator

[0.75 lb] our refrigerator is covered with them!

[4.6 lb] Strong enough to hold up a refrigerator, I think. Fits perfectly, of course.

[4.17 A] Connected to my River, kept my portable refrigerator going all weekend

[Download] Even better than promised. Will try hooking it to my refrigerator.

[1800 W] Charged up wonderful with the extra battery hooked up. Cannot wait to try it out on my refrigerator first.

[f/22] I purchased the Samyang lens in the hopes that I would be able to mount it on the Sigma SD Quattro, as I had done with other Pentax lenses in the past. Sadly, the Samyang depicted on B&H photos website image is incorrect. The image shown on the website indicates that the rear element is free and clear, whereas in actuality the rear mount has a tab protruding (for aperture actuation) near the rear glass element, that prevents the lens from being mounted on the Sigma SD Quattro. I did get the lens to work on an Olympus Micro Four Thirds camera via an adapter and found it to be extremely sharp with good contrast. It is extremely well-built and hefty.

[0.18 lb] I have yet to have an issue with any Sensei product; this good is no exception. Using on a Sigma Quattro DP3 as I simply prefer rubber to metal shades. Works with the standard lens and the conversion extension just fine, no vignetting even with a UV & polarizer combined!

[Sigma BP-51] I got this battery pack as a backup for a power-hungry Sigma dp0 Quattro. It holds charge much better than the old battery, which is not a surprise. It's not always a case with the not genuine batteries. I am glad Sigma is still making it. Get it while you can.

[0.015 lb] I'm super happy with this adapter because I have two Sigma Quattro bodies and a range of Sigma Art lenses which work like a native on my new Panasonic S1R body, meaning my lens investment is not wasted.

[0.2 lb] I bought this for my Quattro DP2, which prefers to run at ISO100 and can make some landscapes a little tricky. In the Pittsburgh, PA area you can often have some spectacular skies to add drama to your cityscapes, but can lose land detail if you stop down to avoid burning the sky. A nice feature of this filter is that it rotates so you can get it into the position you need easily. For my own work, I didn't feel the need for the extra coating and digital-ready stuff, but spent the extra $10.00 USD or so for the rotating feature. What a polarizer can't quite do at times, this filter can, Like all Tiffen filters, it's well-designed and manufactured, right here in the U.S. of A. and reasonably priced. Been using them for 40 years with no complaint!
