Stringed Instrument Quattro

Action is very close to a stringed piano pedal. Holds the notes well. Great product and price

Perfect. My children can now practice their stringed instruments at their desks or any table without having to set up a regular sized music stand. We love the fact that it is manufactured in the USA.

I put this lens on my SD Quattro and it hasn't come off since...and won't! It's an absolute perfect match for that camera in my opinion, it handles 90% of the landscape photography I enjoy doing.

Can’t beat this little instrument for the money!

Fine instrument, does what it should do and more. I recommend it.

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.

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.

I've mounted this on the Sigma SD Quattro H and it out resolves my Hasselblad 110mm f 2 Planer FE, 250mm and 350mm lenses on my lens tests. My only request is that Sigma make a tripod mount for it. I had to improvise one. The movement from pressing my finger on the shutter was greater when the camera body was on the tripod, than when the improvised lens mount was on the tripod. Using the cable release decreases the difference. The SD Quattro H is an amazing camera for its price and the Foveon sensor outperforms my Bayer sensor Nikons (800E) and even my Fuji X-trans on my Fuji XPro 2. The colors are the closest to slide film of any of my digital cameras.

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.

I shoot digital just like I used to shoot LF: everything's on a tripod with manual focus and a loupe. (Sigma Quattro). It seems that I'm always shooting in light that requires the needed sun shield. This is super useful.
