The Tiffen 77mm Warm Black Diffusion/FX 5 Filter diffuses strong light entering the lens and produces a glowing effect. While the resulting image appears softer and ethereal, there is little loss of clarity or detail. This filter works by diffusing the light entering the lens with small aberrations; by spreading the light more evenly, a soft glow is created rather than the sharp, well-defined image when shooting without a filter. In addition to the diffusion provided, a warming effect is also integrated into the filter helping to further balance skin tones. This filter has a 5 density, providing a very noticeable amount of softening.

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, and then mounting to precision metal rings.

Q: 1. Anyone have experience with Tamron's warranty service? I got one of the first batches of this lens and understand mine needs a firmware upgrade to fix focusing issues with some bodies. I know it stalls (AF doesn't engage) on my 5D3 periodically. Seems to work fine on 7D2. Also, dust is gathering under the front element.

A: If you are having an issue with the lens and you are within the 30 day return period please contact customer service, Sales 800.606.6969 or 212.444.6615.Or you can contact Tamron.

Q: 2. does it work with a Canon T5i?

A: Yes, this lens is compatible with the Canon Rebel T5i.

Q: 3. Is this lens compatible with the nikon D7500?

A: It is compatible.

Q: 4. For the D750, which is the better lens: (1) the Tamron 150-600 FX or (2) the Tamron 150-600 for FX and DX? Price difference is approx $400.

A: I assume you're talking about the (older) Tamron SP 150-600 versus the (newer) 150-600 G2? The supported sensor sizes are the same. Any lens that covers an FX sensor (like your D750 has) will also cover the smaller DX sensor (like my D5200).As for which is better, the G2 has some improvements, but nothing I couldn't live without, and the extra $400 would've broken my budget. I'm quite happy with my (non-G2) lens and the extra money in my pocket.

Q: 5. Is this lens FULL COMPATIBLE with NIKON D300s?

A: The Tamron 150-600mm lens will be fully compatible with the D300s, yes.

Q: 6. Is this lens compatible with Nikon D3500?

A: Yes, this lens is compatible with the Nikon 3500. Since that camera is a DX/APS-C, the smaller sensor will, in effect, magnify the image. This is a great advantage for people who need to photograph birds or sports.

Q: 7. Will the auto focus on this lens work with my D90?

A: Yes it will. The D90 has no autofocus restrictions such as other lower tier Nikon cameras do. It will autofocus with any autofocus lens made for the Nikon mount.

Q: 8. WILL IT WORK WITH CANON EOS 70D?

A: I use this lens on my Canon 70D... it works great. The combination works best with lots of light. The focus hunts quite a bit in low light, so I manually set focus in those situations. It's a bit heavy, but is a great lens for the money!

Q: 9. Will this lens auto focus with Nikon D3100?

A: Yes, it will autofocus with the Nikon D3100. The lens features Tamrons USD UltraSonic Drive Motor to autofocus with the D3100.
