GGS Swivi HD DSLR LCD Universal Foldable Viewfinder Version II with 3.0X Magnification

So disappointed that I could not use this on my Nikon D810 with the vertical battery grip attached to it. The vertical rails on the left and right sides of the adjustable bracket mount that allows for lowering and raising the loupe needs to be 1.5 inches taller and the flat slide-in tongue portion of the same bracket mount needs to be 0.75 inches longer due to the width of the camera and vertical battery grip. The loupe size was perfect, however, and would fit perfectly onto my LCD screen, allowing full view of whatever was on the screen, including the menus and whatever I was filming or photographing in Live View, all the way to each corner of the LCD. I really wish there was a way to modify this Swivi II viewfinder/loupe. The plastic lenses of the unit were secured well, the blades of the viewfinder open and close easily with a slide switch at the top, the diopter adjustment wheel seemed to work well enough to get sharp focus. Overall, I was very happy with the build quality and features of this unit, but was sorely disappointed that the bracket was slighty too small to fit my D810. When I attempted to visit their web page to see if there was a larger bracket I could purchase, their website [ www(dot)swiviusa(dot)com, printed on their packaging] had expired, according to the pop-up message. It would not be difficult for this manufacturer, Swivi USA, to make a slightly larger bracket so it could be fitted to larger pro DSLR cameras. If only I could reach the company...

Just what I was hoping for. I've owned and used the Perfect 3.0X and the Sigma LVF-01; this is better than either of those. The Perfect 3.0X worked well enough on my DP3 Merrill, but it was held to the LCD panel with glue which lost its grip in the hot sun of New Mexico. The Sigma LVF-01 works well, but only fits Sigma's Quattro series of DPx's, is rather pricey, and comes with a sun-blocking cap that dangles on a string. (One of the problems with viewing hoods is that if you absent-mindedly let the sun shine into the viewing lens, it can ruin your LCD.) The Swivi is well made, designed to fit most cameras (all sorts of adjustments, including an extra-high rail in case you're using a camera with a large battery grip), has a very large eyecup (usable with glasses), a good diopter adjustment, and a shutter (not a cap) to block direct sunlight. True, because of the adjustments it's a bit larger than either the Perfect 3.0X or the LVF-01; that's no problem for me, since I use my Sigma Foveon DPx's as studio/field cameras, on a tripod or in the studio with monolights.There's no problem attaching a tripod quick-release plate to the Swivi. I use the Manfrotto release plate. Note that other reviewers say you can use the Swivi's own base plate (part of the kit) directly with some other tripod heads.I'm very pleased and wish I'd bought this item before the others I've tried.

The greatest thing since sliced bread. This one does not fit the 1DX mark 3 or any camera with a battery grip the mount rack it is just too short.This does come in another model that you can find that has a much longer mount but they are hard to find And it requires some modification. This allows A DSLR to act like a mirrorless camera in live view and is very awesome it allows people with vision issues to see clearly the screen. If you have a standard DSLR this is the hot ticket if you wanna do video or live view.

This is a darn nice viewfinder. The fact that it is a fraction of the price of Zucato and the like is icing on the cake.For Nikon D800 users: Yes, it fits. But not the way I would prefer it to fit. I mounted the base plate, centered on the body. After mounting the viewfinder, I noticed it did not want to stay in place. After studying the parts, I realized the "tab" that fits in the base plate is slightly short for the thick body of a D800. I solved this by moving the base plate rearward - closer to the back screen. It doesn't stick out, but it isn't centered on the body. Not a big deal, but not a "perfect" fit. But a darn good fit, overall.With that out of the way, I've found that it really helps steady the camera. In fact, I'm stopped using my shoulder mount rig. I really didn't expect that. So it is well worth purchasing.The base plate fits my Arca-Swiss ball head, the Kirk head on my monopod, and the RRS clamps as well. Since a good Arca-Swiss style base plate costs about $65, this viewfinder is an amazing deal. The plate is heavier than a RRS, and the fit and finish are not as good. But the RRS stuff is amazing, so I can't fault GGS for that. The finish is good, and over all I'm pretty happy with it.Bonus - that huge eyecup works even when I wear glasses! Now, that is a big damn deal for me.Get it. You'll be damn glad you did.

I have a canon rebel t3i, I really like this product for filming though I never use the screen zoom toggle. Looking through the viewer when I film gives me a cinematic perspective. Its built very sturdy but as for making it fit snug to my screen, I had to bend the L bracket less than 45° so when i assembled the two peices, i could then press it snugly to the screen and tighten the screw. But after all that I really liked this product. Sad note, My puppy eventually chewed up the rubber eye viewer, and there are no replacement parts. Kinda a bummer. I have different set up now for filming but this was good while it lasted. Side note. I let a friend borrow it and she dropped my camera! But it fell on the base bracket and only chipped it. Thing lasted me a few years and only died by misdeeds.
