Rosco Fluorescent Lighting Sleeves/Tube Guards are a very reliable and cost-effective system for easy control of tough lighting scenarios- especially under fluorescents. In addition to the financial benefits of the sleeves, they protect against the potential disaster of glass shattering by containing the lamp within the end caps.

Rosco sleeves are constructed of a solid polycarbonate tube within which is held the specific filter. The choice of filters and combination of filters is endless - there are complete Roscolux, Cinegel or E-Colour color filter lines - something for every venue, every photographer, every cinematographer.

Q: 1. Does this lens have the sigma manufacturers warranty?

A: Yes. As we are an authorized retailer, it comes with a 4 year (1 + 3 extended) USA warranty from Sigma. Please see/register your warranty on Sigma's page here: https://www.sigmaphoto.com/service-support/warranty-registration

Q: 2. What is the max aperture at 150mm - comparable to the max aperture of the Sigma 150-600 f/5-6.5 at 150mm?

A: The max aperture at 150mm on the 60-600mm is f/5.3. As soon as you hit 150mm it switches to f/5.3, if you're at 149mm it's f/5.

Q: 3. Is this the new, 2023 model or the 2018 model?

A: The 2023 version of this lens is only for mirrorless cameras. The Sigma 60-600mm f/4.5-6.3 DG OS HSM Sports Lens (Nikon F) is a brand-new copy of the original 2018 design.

Q: 4. will i reatin the auto focus with the sigma tc 1401 ? i have the canon 5d mark iv and the canon mark iii body's

A: No, you would not. When using the Sigma 1.4x Teleconverter (TC-1401) with the Sigma 60-600mm f/4.5-6.3 DG OS HSM Sports Lens, the lens will become the equivalent of a 84-840mm f/6.3-9, while when using the Sigma 2x Teleconverter (TC-2001) on the Sigma 60-600mm f/4.5-6.3 DG OS HSM Sports Lens, the lens will become the equivalent of a 120-1200mm f/9-13. The Canon EOS 5D Mark IV DSLR camera's autofocus sensor requires the lens to have a maximum aperture (or equivalent maximum aperture) of f/8 or brighter to retain autofocus. The 60-600mm lens would not focus with the 2x teleconverter as the equivalent aperture range is f/9-13. When using the 1.4x teleconverter, it would still be recommended to focus manually, as the equivalent aperture range would be f/6.3-9. While the lens may try to autofocus on the wider focal lengths, focus would be slow, and you would lose focus capability as you zoom to the telephoto zoom settings.

Q: 5. Does this work on the Canon R7?

A: Sigma 60-600mm f/4.5-6.3 DG OS HSM Sports Lens (Canon EF) BH #SI606004563C will work on the Canon R7 with the Canon Mount Adapter EF-EOS R BH #CAMAEFRF.

A: Yes, the Sigma 60-600mm f/4.5-6.3 DG OS HSM Sports Lens for Nikon F along with a Nikon FTZ series adapter can work with the Nikon Z9.

Q: 9. Will this work with a Nikon D7500 and if so would it need an adapter?

A: Yes, Sigma 60-600mm f/4.5-6.3 DG OS HSM Sports Lens is design for Nikon F mount cameras. You can mount the lens directly to your Nikon D7500 DSLR. Due to the camera APS-C sensor with 1.5X crop factor the lens focal lenght will increment to 90- 900mm.

Q: 10. What is the "official, precise" minimum focus distance at 600mm? I know the specs say that the MFD is 1.97', but that can't possibly be true even at 600mm, because then the magnification would be much greater than the 0.3x that is stated.

A: According to Sigma, they list the Sigma 60-600mm f/4.5-6.3 DG OS HSM Sports Lens as having a minimum focusing distance from 23.6" to 102.4".
