A small second monitor with 7 inch I have. That is unfortunately quite cumbersome in vacation. As a display magnifier I have already tried a Hoodman and the Zacuto-Lupe. The Hoodman I found with the strap too unstable and with just over 100 euros for a bit pricey. Zacuto is very stable (up from the professional sector). But very expensive and it has a holding device for the magnifier are screwed, which means extra weight and the camera makes bulkier.
As Viewfinder there but as the present dozens of here, the. A stick-thin frame on the display, which is magnetic, the magnifying glass should then fix Especially in a large auction house they are offered at a competitive price for just over 10 euros and go up to 100 euros. The price difference is because the are very reasonable shipped directly from China and contain fewer accessories.
The best price / performance ratio has in my opinion it here. It's a small carrying bag about to be able to keep a cord around the detached Lupe easy and a cleaning cloth for the screen. The delivery of luck Express was great and very fast. So no reason necessarily to buy a magnifying glass labeled from Germany. Especially excited I was, however, whether the magnifier really keeps the frame. She does fine, as not only the magnetic lock holds good but also small projections closer look additionally stabilize the frame. Nevertheless, she read easily fall again. The processing is knotless. With magnification x 2, you can make good sharp. And a lot of high contrast screen brings whatever the ambient lighting. If you look through the magnifying glass so you can fix the camera with an extra point good and reduces the shaking of the hand significantly. The Augenmsuchel is very pleasant. One can even buy a Blue Star Eyecushion Okularpolster for some extra money. Only those with vision problems, there is no diopter compensation. Who here has problems, have to buy a corresponding motion. Also, the adhesive can be apparently no problems remove the monitor as a film in a known video portal shows.
Overall, I am very satisfied. A really useful and practical accessory for very little money! As a camera, I have the Canon 5D Mark 2 and a Sony Nex 5R.
