Nikon BF-3B overview

  • 1Description

The Nikon BF-3B Replacement Front Mount Cap for Nikkor AF-S Teleconverters replaces the BF-3A. It is a protective cap that goes on the front of your teleconverter. A tight seal, thanks to the bayonet lock, prevents liquids, dust and dirt from ruining your teleconverter. This cap is compatible with the TC-14E II, TC-17E II, TC-20E II and TC-20E III teleconverters.

Nikon BF-3B reviews

BF-3B Replacement Front Mount Cap for Nikkor AF-S Teleconverters is rated 4.8 out of 5 by 32.
Rated 5 out of 5 by from Great product -- faint color. Great product, why? Because the faint color (gray) virtually broadcasts that this is not just another small lens (say, a 50mm/1.8); rather, it is a TELE-CONVERTER! I.e., if that's not what you want, then reach for something else. Plus, on most tele-converters the bulbous head is REQUIRED so that you do not damage the protruding part of the lens. It is actually NOT required for the old TC-14B (came with a black BF-3). But I switched the cap to a BF-3B anyway, so that I immediately recognize it as a tele-converter.

Rated 5 out of 5 by from Gotta- have These teleconverters are snap,crackle,Pop,But what to do when your done.Presto,and twist.For some reason this cap and teleconverters are a go to item.Nice tight friction connect,it is going to stay on.Jar like.The gray color is me,I,am ok with it but prefer basic black with red connect dots, the style on my old TC-20e.,worth getting if you need it , as it covers delicate connect points on converter.Same quality as my black cap one.Steep price, but in the nikon name does what it is suppose to.

Rated 5 out of 5 by from Unbelievable Performance!!! This cap is a stunning gray color, and looks tres chic on both of my Nikon extenders. How have I lived without it? It's been tough since one of them wandered away, but now my prayers are answered. And it's real Nikon plastic, not some gray market wanna be. It goes on like a hot knife through butter, and on it stays, protecting my substantial investment in Nikons overpriced extenders. If I were you I'd get one (nothing else fits), heck get two, they are small, and if you lose one you're stuck.

Rated 5 out of 5 by from Use only the original cover sometimes teleconverters do not come with this cover, but it is a must if you have several TC. It will fit any Nikon camera body, but the camera body caps will not fit the TC 1.4 1.7 and 2.0 without being in contact with the glass and/or possibly damaging the rear element. It is grey so you can easily distinguish the difference. Even if your TC comes with one, it is not a bad idea to have an extra since you never know when you may loose or damage one

Rated 5 out of 5 by from Nice improvement over the original I updated two of my original teleconverter front mount caps with these new ones. These are slightly taller and therefore a bit easier to grab, especially with the increased size of the side ridges. Overall, not a necessary upgrade by any means, but I felt it was worth the minor cost based on the benefits.

Rated 5 out of 5 by from It fits wonderful I purchased a used Nikon TC17 that was missing front cap. Checked around nobody had the rite product available locally, so off to BH. They of course had it, I bought it, they sent it quickly, it arrived in pristine condition and is now protecting my gear. Great company, good service. Thank you BH.

Rated 5 out of 5 by from The Best Ever This turned out to be the most best-est BF-3B Replacement Front Mount Cap for Nikkor AF-S Teleconverters by Nikon I have ever owned...ever! Admittedly I have not owned a lot, so this is based on a very limited sample of one. But I stick by my 5 star rating.
Date published: 2014-08-28
Rated 4 out of 5 by from Improved cap! This cap is improved from the BF-3A version. Fits nice and snugly. Even easier to spin on and off. Not sure I can give it 5 stars unless it also takes itself off by mental connection. Be nice if it were't so expensive for a little cap!
