Canon 300Mm F2 8

[Front] As its a Canon it fits my 70-300mm lens exact

[66 to 68 mm] When on Canon FD 300mm f/4 lens - used to shoot video

[100mm at f/5.6] Does exactly what it is supposed to - certainly beats the original cover for the Canon 200 F2.

[Aluminum] Is this product suitable for Canon Rf 28-70 F2 lens ?

[f/1.4] WOW!! I used to have the Canon 135 f2 but sold it right after receiving this Sigma 85mm f/1.4. Super sharp with gorgeous bokeh! The only negative...the ONLY one...is that I hate the lens weight. It is kind of heavy on your neck. Probably i need a shoulder belt to carry the camera with this lens.

[Empty] I bought this case for the Canon 35mm f2 IS lens. It was the recommended pouch for that lens. It dows seem a bit on the large size for that lens, but if needed I can leave the hood attached ready to go and it still fits this case. When the hood is reversed this soft pouch can be folded over at the top to take less space in the camera bag. The only down side is that it wasn't included with the lens itself and had to be purchased as an additional accessory.

[Aluminum] I use this on my Leofoto MT-03. Securely holds my Canon R5 with Canon 28-70mm f2 lens.

[Glass] This filter will live on my Canon RF 28-70 F2 lens when shooting on a sunny day! Without it I could not shoot wide open even at 1/8000th a second! No issues with color cast or stacking other filters. I have used it stacked with the 6 stop ND filter (same brand) and the PolarPro 95mm QuartzLine CPL and am happy to report you can still install the lens hood with all 3 stacked!

[55 mm] This is definitely a pricey filter, $250, however I believe it is one of the best. I am not going to put a $20 filter on a Canon RF 28-70 f2.

[Aluminum] I’ve been using this on my canon m6 mark ii and lumix gx85 with a TTartisan 25mm f2 and a ttartisan 50mm f2. It allows me to create dramatic skies with editing as I almost exclusively shoot in black and white without artifacting in Lightroom.
