The Tiffen 6 x 6" 85B Color Conversion Filter helps to decrease the color temperature from 5500 to 3200K, allowing the use of tungsten-balanced film in daylight conditions. The warming effect of this filter requires a 0.6-stop increase in exposure for normal results.

This filter is made using ColorCore technology, a process that involves laminating the filter substrate between 2 pieces of optical glass and grinding flat to a tolerance of 1/10,000th of an inch. It measures 6 x 6" / 152.4 x 152.4mm.

Q: 1. How do these hold up compared to brands like LEE or ROSCO?

A: These are all very similar gels that will hold up to heat.

Q: 2. anyone tried attaching to the bottom handle instead of the wheels? I imagine this way you could roll or carry at any time

A: Hello Mark F,I bought two of these as I thought is was a perfect idea.In my work I use many different Pelican Cases every day and the idea of a back-packable 1510 seemed brilliant. Alas....I've tried to use these straps as the instruction say, I've tried all sorts of mods, longer screws with a D-ring, drilling holes for the straps, etc, but there really is not an effective and easy way to attach the bottom straps other than over the wheels. If you do finally get them attached that way the straps will slip off the side of the wheels and get bunched up in the area and become very difficult to undo. IMHOI wish Pelican would take this idea and do it right. All the best!Julian

A: Tiffen 37mm 0.65x Wide-Angle Conversion Lens BH #TI.65WACL wouldn't fit on any of the standard size Canon interchangeable lens. Depending on what lens you have, you might have to use a step down adapter.

Q: 10. Any padding in this, especially for lower back or does it make the hard shell hit against your back?

A: the harness works well.. but is a little snug to fit. there is no padding- this includes lower back, but it really doesn't engage lower back.. it presses against the upper part of the back (although, i'm 6'2 .. so maybe it rests differently if you're shorter). it's hard against one's back, but i've never felt any ill effects. i've climbed up steep/ long staircases in indonesia, had it on my back on a scooter.. it's served its purpose well. i was concerned about its durability from reviews but have found no issues. i recommend it.
