The Tiffen 138mm CC10B Blue 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.

Blue is the opposite of yellow and can be used to reduce yellow tones or casts within a scene or print. This blue CC10 is more dense than a CC05 filter and less dense than a CC20 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.

Related Questions and Answers

Q: 1. will it work on a canon 6D?

A: No, sorry. This lens was made specifically for a crop camera. The Canon 6D is a full frame camera.

Q: 2. I just purchased the Canon T6i and have an older Tamron 18-270 that I purchased about 7 years ago. It's been a great lens I used on my Canon T1i. Is there more improvement in this Tamron 18-300 that I would notice on my new camera?

A: I too had the Tamron 18-270mm on an older camera and now have the Tamron 16-300mm on my Canon 70D. In my opinion, moving up to a newer/better camera is the biggest plus - my 70D is far superior to the T3i I had prior. As for the lenses - there is a little more range (definitely a plus!) and I think the 16-300mm is a little quieter and focuses a little quicker. I've been very happy with the upgrade and chose another Tamron because they stand behind their product and actually honor the warranty - without attitudes!

Q: 3. does this lens have lens creep?

A: I've been using this lens for over a year and have never had an issue with lens creep. This is a great all in one lens that I highly recommend!

Q: 4. I know this lens will physically 'fit' the mount and therefore in theory be compatible with the EOS 7D Mark II - but what about functionality? Do all 7d Mark II camera features work okay with this lens?

A: I have never had a problem with this lens and all the possible ways to use it on the 7D II. It may lack the quality of say a Canon L lens, but functions equally well. This is a great lens for travel.

Q: 5. Is it compatible with full frame camera - canon 6d?

A: I don't think it is compatible w 6d. the info says for APS-C cameras, and the rear probably protrudes into the sensor area like Canon EF-S lenses do. Tamron makes a 28-300 lens for full-frame bodies.

Q: 6. Will it work with olympus Teleconverters?

A: Olympus teleconverters are only compatible with a small number of Olympus lenses; they are not compatible with the Panasonic Leica DG Vario-Elmar 100-400mm f/4-6.3 II ASPH. POWER O.I.S. Lens.

Q: 7. Will this work on an old canon D60. Not the newer 60D. It is a small sensor camera but made long before the specific mounts for small sensored cameras. I assume it won't work but figured I'd ask.

A: Sorry Buddy, I don't have a clue about the D60 electronics.

Q: 8. I currently have a Canon EF-S 18-135mm (f/3.5-5.6) IS STM lens and a Canon EF 70-300mm IS USM lens that I use on my 70D. Q1) Is this Tamron 16-300mm lens as sharp as my 18-135mm lens? If not, where would the difference be most noticeable?Q2) Since the Tamron 16-300mm is designed for APS-C cameras and my EF 70-300 is designed for full-frame cameras, will I get clearer images from the Tamron throughout the 70-300mm range? If not, where would the difference be most noticeable?

A: I have the same camera and lenses you have and I did buy the Tamron 16-300mm too - more for the convenience of traveling with one lens. While I am not super knowledgable (still learning!!), what I did notice is that when I took pictures with my Canon 70-300mm at the 300mm range, then took the exact picture in the exact spot with the Tamron lens, the picture taken with the Tamron lens is NOT as close. There is definitely a difference. As far as clarity, I do not see a differnce, but again, I'm not super knowledgable in being able to pick out the differences. I've had a Tamron lens in the past with a different camera and was very satisfied with the quality as well as the customer service and support when I encountered an issue. I'm keeping all three lenses - absolutely love the convenience of the 16-300mm range on the Tamron when wanting to travel light, but I still fall back to my Canon 18-135mm when taking pictures of the grandkids, and will continue to fall back to my Canon 70-300mm when I know I'm doing longer range shots only.

Q: 9. Does the lock switch only work when set on mm18... cause I know the 18-270 tamron only had the lock switch work while on the 18mm mark.

A: yes, it only locks at 18mm setting.

Q: 10. with a Nikon D300 will this lense work automaticly with a tamaron 2x teleconverter or is it better with the Nikon 2X teleconverter

A: Unfortunately, the Tamron 16-300mm lens is not compatible with a teleconverter. Lenses that have a wide angle have a lens construction where the rear element sticks out far more than lenses that have a 50mm or longer focal length. For this reason, lenses that have focal lengths wider than 50mm are not typically compatible with teleconverters. Even if you could fit one on the back of the lens, you would risk seriously damaging the rear element of the lens and the teleconverter itself.
