The 138mm Streak 2mm Filter from Tiffen is a special effects filter designed to render a single light ray from a point light source. This filter features a single series of etched lines spaced 2mm apart from each other, which run diametrically across the filter surface. This filter is set in a non-rotating mount and can be used in conjunction with a filter holder or matte box to adjust the orientation of the light ray to suit your composition or desired effect. It is constructed from clear optical-grade glass and mounted in an aluminum filter ring.

Single Light Ray from Point Light Source    Etched Lines are Spaced 2mm Apart    Aluminum Filter Ring    Optical-Grade Glass Construction

Etched lines spaced 2mm apart produce a single ray of light from point light sources, strong highlights, reflective materials, or metallic surfaces.

Filter is designed to be used in conjunction with a matte box or filter holder for adjusting the orientation of the light streak.

Optical glass construction and clear filter substrate help to maintain the original image quality and do not affect the overall color or contrast.

Q: 1. Has anyone used this as a spotting scope for benchrest shooting? If so, what would be the maximum effective yardage for viewing the target?

A: I really would not recommend this for Benchrest Shooting. I would go with something with a zoom eyepiece. This model really acts like a telescope with different interchangeable eyepieces. I would personally recommend the Redfield Rampage 20-60x80 Spotting Scope Kit. This would be a good choice for Benchrest Target Shooting.

Q: 8. I have a Sony NEX-6 with the 6-50 OSS lens. I want to get a telephoto zoom and trying to decide which one to get and whether to get an 18-200 or a 55-200?

A: This is one situation where it seems the 18-200mm lens may slightly out-perform the two-lens setup of the 16-50mm and 55-210mm lenses. While image quality does typically prefer the two-lens setup, the 18-200mm lens is well-designed (as indicated by its price), and the main struggles it would have would be with chromatic abberation, and slightly with distortion on the wide-end of the zoom; however, even for the all-in-one lens, it performs better than the 16-50mm lens at 16mm natively. When using the 16-50mm lens and the 55-210mm lens, some of the optical issues can be corrected simply by activating the camera's Distortion Correction feature, which also assists in correcting for vignetting. Basically, if you are on a budget, the two lens setup would be a good option, using the camera's Distortion Correction feature, but if you need a one-lens-does-all solution, then the 18-200mm lens is a good option on the NEX camera platform.
