The Tiffen 138mm CC30Y Yellow Filter is a color compensating (or color correction) filter for use when making color balance adjustments. It can be used to alter the color balance of a scene by placing in front of a light source or the lens of your camera. It can also be used to apply color corrections when used in the darkroom with an enlarger or to help pre-visualize color adjustments when viewing prints.

Yellow is the opposite of blue and can be used to reduce blue tones or casts within a scene or print. This yellow CC30 is more dense than a CC20 filter and less dense than a CC40 filter, and requires a 0.3 stop compensation for normal exposure results.

Tiffen filters are made using ColorCore technology; a process that involves laminating the filter substrate between 2 pieces of optical glass, grinding flat to a tolerance of 1/10,000th of an inch, then mounting to precision metal rings.

Q: 1. Can this lense be used on my a77! And will it give me a good result or I should upgrade the body to the a7rii!

A: I echo the answer given by John. I believe a77 is compatible with A-mount lenses. The FE 70-200 GM is for E mount cameras. So, I don't think it is going to fit your camera unless an adopter is used.

Q: 2. Is there a collar that makes the new Z lenses backward compatible with existing F mount cameras (Nikon 850)?

Q: 6. I’m thinking of purchasing this, how would I mount an M50 or M6 MKII to it?

A: All you need to add is a T-mount adapter and camera-specific T-ring. The T-Ring couples your 35mm SLR camera body to the T-Adapter, radial guider, or tele-extender. This accessory is mandatory if you want to do photography through the telescope. Each camera make has its own unique mount and therefore, its own T-Ring. Celestron has 8 different models for 35mm cameras. you may also need an Canon EF-M Lens Adapter Kit for Canon EF / EF-S Lenses for your camera body.

Q: 7. does this lens focus manually as well as AF? I just got it and when I turn the focus ring I do not see any change in focus.

A: I think the answer to your most recent question is it depends , e.g.,If camera is set to AF-S and you use back button focusing with lock-on when you lift your thumb off the back button, then you can tweak manually. If you use shutter button (half press), and then, keeping it half pressed, tweak manually it may work.If you use AF-C the camera will override any tweak/s.If you set Direct Manual Focus (DMF), it will start as AF-S and then go to manual focus mode where you can tweak the focus -- it will stay in manual focus as long as you are in half press shutter button. DMF is even more helpful if you have set Peaking Level and Color.

Q: 8. why is this lens so expensive?

A: If you remember the Azanuma zooms of the 70's, this is way betterbut so was everything else& just rent it first if you are not sure so that you don't end up complaining and explaining that you purchased it and then got charged a restocking fee when you returned it in some insipid equipment review. At the end of the day people are gonna end up with what they can afford, like, and can actually live withirrespective of any reviews.
