JJC ET-74B Bayonet Dedicated Lens Hood Shade for Canon RF 100-400mm f/5.6-8 is USM and EF 70-300mm f/4-5.6 is II USM Lens, Replaces Canon ET-74B OEM Lens Hood

Fits my lens perfectly, quality appears to be good, and is much more reasonably priced than Canon's hoods are. This is my 6th JJC hood; none of them have disappointed. I do have two Canon hoods (one came with the lens), and as far as I can tell, JJC and Canon hoods are equivalent in all respects except price.

This is an ET-74B hood for Canon RF 100-400 lens.It is well made and fits well. I suppose it closely matches the one made by Canon in quality and design. It attaches easily and clicks into place. You have to jiggle it very slightly when taking it off, but I didn't deduct any points for that. It's certainly better than some other lens hoods I have bought.There are some excellent qualities that I have not seen before in non-OEM lens hoods. It's quite stiff around the diameter where it fits to the lens. That means that it doesn't distort when you try to attach it, so it fits well and it's easy to attach. It clicks into place, and a well-placed button releases it from the lens. It can be reversed for compact storage. There are two marks to position it correctly for mounting in either position.There is one feature which may be either good or bad. The inside has a black, matte surface to reduce surface reflections, but it lacks flocking. Many of the original Canon lens hoods are made like without flocking, and I think this one is not an exception. Flocking is a black, velvet-like material that further reduces reflections, and it's found on some hoods for the best lenses. I am not sure whether it is needed for this lens. Moreover, flocking has to be cleaned occasionally, and it could wear out.

works as intended. Has enough strength to break a fall yet weak enough to absorb that fall. Good stuff.

Its fits well and does the job, definetly worth the buy for the price!! I gave it one less star since its not perfect but I love it!

Nice quality, fits great, good finish on product.

It fits the RF 100-400 lens perfectly, it does fit in "reverse position" too. Half the price of the Canon one and quality seems high. I have JJC lens hoods for other Canon lenses and have been well pleased.

This lens shade does its job very well. It shades your lens just as well as the $45 Canon ET74B lens shade. Plus it has a lock to secure the shade to the lens. Press the unlocking tab to remove the shade. It’s made of plastic but so is the $45 Canon lens shade. Spend $13 or spend $45 to shade your lens. It’s up to you.

I Have this on the RF 100-400 USM cannon lens fits snug and good lock into place easily and sturdy and you can still put on the lens cover while hood is attached, the hood can also be attached in reverse for storage. Overall great!
