Related Questions and Answers

Q: 1. Will this E-180D Lens cap fit on the mki version of the Canon EF 400 f/2.8 IS?

A: While it may physically fit, it is not designed or fitted for that lens. This lens cap is specifically designed for the Canon EF 400mm f/2.8L IS II USM lens, only.

Q: 2. Is this a glass surface?

A: This product has opaque plastic top.

Q: 3. Your specs indicate a CRI of 88. But on the Kaiser website they claim a CRI of 95 for this unit. Why the discrepancy? Two other models of this on your site claim a CRI of 95. Are they different in this regard?

A: The specs have been updated to reflect the current model.

Q: 4. Does it fit the 300 f/2.8 IS (ie non II) and is it meant to be used without the lens hood or is that not recommended. thanks

A: This lens cap is designed specifically for the Canon EF 300mm f/2.8L IS II, as this lens does not have a threaded front filter. The older version of the 300mm f/2.8L IS has a front filter thread, and can take any 77mm lens cap, such as this one by Sensei: http://bhpho.to/1dXg1ua. It is not advised to use the E-145C with the lens hood.

Q: 5. Does it fit a 300mm 2.8 second generation?

A: Yes, the Canon E-145C is designed for version II of the 300mm f/2.8L lens.

Q: 6. Will this Cap fit the 300 2.8L VI? Hood reversed stored in the hard case. Not talking about the 77MM lens.

A: Yes, the Canon E-145C Lens Cap will fit the EF 300mm f/2.8L IS II lens.

Q: 7. Does the surface of the lightbox stay cool in use? We plan on using it to photograph negatives and transparencies.

A: This should have no issues with getting hot when using.

Q: 8. Will this cap fit the Sigma 15-30mm 1:3.5 - 4.5?

A: Since your lens is no longer made, I see why you are considering this cap since we do not have a replacement cap and I think unlikely that Sigma does as well. So some fudging is in order. The Sigma Lens Cap for 14-24mm f/2.8 DG HSM Art Lens B&H # SILC96401 is meant to fit on the Sigma 14-24mm f/2.8 DG HSM Art Lens. This lens has a 3.8 diameter. The no-longer-available Sigma Zoom Super Wide Angle 15-30mm f/3.5-4.5 EX Aspherical DG DF Autofocus Lens for Pentax AF B&H # SI153035PAF has a maximum diameter of 3.4 . I would order the cap and some Velcro. Apply the soft side of the Velcro to the inside of the cap to make up for the size difference. You may have to also apply it to the diameter of the lens. Velcro VEL-90209 Set of 4 Touch-fastener Strips (Black) B&H # VEVEL90209. Good luck.

Q: 9. what's the maximum brightness in lumens? and how slow of a shutter do you have to go down to in order to expose properly if your aperture is at f8 and iso at 100

A: At F8 and 100 ISO to expose for the light you would have to be at 1/4 second , when you put a slide in front depending on the slide you would be at 1/2 to 1 second exposure

Q: 10. Do you carry the charger for the Kaiser Slimlite Plano 5000K Battery/AC Lightbox (10.5 x 15.5")?
