Designed to the principals of "Smaller, Lighter, Brighter, Sharper," the Opticron MM4 50 GA ED 12-36x Travelscope Straight Viewis built with extra-low dispersion (ED) glass and fully multi-coated optics and measures just 8.1" long. The glass and coatings ensure accurate color rendition with improved clarity and contrast, while the 50mm objective lens draws in copious amounts of light to boost its performance in challenging conditions such as dawn and dusk or when trying to see into wooded areas under dense canopies. The short form factor enables users to hand hold it for convenient glassing on the go without a support system.

This iteration of the MM4 50 GA ED is offered here without an eyepiece for those users who already own Opticron eyepieces and are looking to upgrade their scope and is compatible with HR, HDF, and SDL eyepieces. The 2-speed focusing system features an 8:1 reducer gear to allow for fast coarse and precision fine focusing, and the straight-through viewing configuration makes finding and tracking subjects faster and easier versus angled designs. For optimum eyepiece orientation, the tripod collar rotates up to 90° in both directions, and a 1/4"-20 mount makes it compatible with many tripods, quick release plates, and other popular support systems like window mounts.

A: I use this track in a reproduction studio, and the full weight with castors, legs, head, slider, rails, and medium format camera with lens, is around 30 pounds.

Q: 7. Is this strong enough to use with a doorway dolly?

A: What doorway dolly? This track is designed for use with the same manufacturer's Glide Gear SYL-960 Floor/Track Hybrid Tripod Dolly. That dolly has a rated capacity of 35 lbs. If you mean something like a Matthews Round-D-Round Doorway Dolly, that one has a capacity of 1100 lbs. So I would say no. Also keep in mind, doorway dollies cannot directly ride on these rails without skates.
