Frequently asked questions
Which lenses is this compatible with?
Only specific Canon L-series telephoto lenses - primarily the 70-200mm f/2.8L IS, 300mm f/2.8L IS, 400mm f/2.8L IS, 500mm f/4L IS, 600mm f/4L IS, and 800mm f/5.6L IS families.
What's the difference between the Mk II and Mk III?
The Mk III (2010) adds weather-sealing, improved optical coatings, and re-optimised correction for current-generation L-series telephotos. The Mk II remains optically capable on the lenses it was originally designed for.
Will it work on Canon RF mirrorless bodies?
Yes, via the Canon EF-EOS R adapter. Autofocus and IS are preserved, and the lens functions normally on R, R5, R6, R7, R8, R50 and other RF bodies.
Why buy from Bass & Bligh
Bought from a real shop, not a warehouse.
Dispatched on the Monday… great service
Ordered a Panasonic four thirds lens dispatched on the Monday after purchase and delivered on the following Tuesday great service. Tried on the camera and initial thoughts are wow pin sharp and clear photos. Thank you
George P.Ordered a lens onlineA proper little treasure trove
3rd time I've been to this shop to treat myself to some new kit. Always very friendly and knowledgeable. Fairly priced too. I would highly recommend a visit if your nearby and looking for camera gear. I'd say if they don't have what your looking for, it's probably not possible to find anywhere. It's a proper little treasure trove.
Philip B.Third visit to the shopBrilliant advice with awesome customer service
Sure you can buy online and possibly save a few pounds.. but if you require and appreciate knowledge and brilliant advice with awesome customer service then it's a no brainer...This is a real camera shop like it used to be back int day..
