New 70-300 f/4-5.6L IS extended length pic

I suppose there's no way to know for sure until some reviews come in. Based on the aperture change points for the current 70-300mm DO and non-DO, and the 100-400mm in terms of percent of zoom where the aperture shifts, I'd guess the new 70-200mm will be at f/4.5 before 100mm, at f/5 well before 200mm, and drop to f/5.6 a little after 200mm.

LOL, going to have to get use to a white lens with no tripod ringmount, maybe they should have left itin black.

The canon web site list the tripod ring as an accessory. I bet it comes with one, a hood and carrying case as well. In case it doesn't come with it, you could always take your tripod ring off your white glass and practice so that you are ready for it.

On the Canon site there is a tripod mount - C listed as an option. On the Adorama site it is listed as included with pre-orders. Needs verification before ordering IMO. I ordered the tripod mount - D for the 100mm f/2.8L IS Macro lens and it was expensive. The quality is excellent although the China knock-offs were much less expensive. But quality? Didn't take the risk. No price given on mount -C that I can find if needed to be ordered alone.

Guess we'll have to wait. My guess is that Adorama is wrong, and it's an optional accessory (and will likely be nearly $200, and not available at first, if the Tripod Ring D for the 100mm L Macro is any indicator).


In their Digital Learning Center writeup, Canon states, "An optional Tripod Mount C (WII) is available, and its operation likewise is both solid and smooth..."


On the other hand, on Canon USA's EF Lens Lineup page for the lens, Canon states, "Gleaming white, with a removable tripod collar, dust and water resistant construction, and a newly developed Fluorine coatingthat keeps soiling, smears and fingerprints to a minimum, its phenomenal performance and flexibility is assured." The Tripod Mount Ring C is listed on the Supplies and Accessories for the lens, but so are the pouch and hood, and those are included.


Given the length of the lens, and the fact that it's closer in weight to the 70-200mm f/4's with the optional ring than to the 70-200mm f/2.8's with the included ring, and also given the fact that if Canon can find a way to make more money, they will...I'll be surprised (very pleasantly, though) if they include it with the lens.

Hi John,


I've also noticed that the 70-300 mm L requires a 67 mm filter whereas the 70-300 mm DO requires a 58 mm filter. Do you think this could impact the aperture ranges ofthe70-300L?


Granted, anything better than what you've outlined is probably a little optimistic.

I doubt it. The main difference between the new 70-300mm L and the 70-300mm DO is that the new lens starts at f/4 (like the old non-DO), whereas the DO lens starts one-third stop narrower at f/4.5 - that sort of shifts the transitions (since the DO has only 2/3-stop variation, while the other two vary over a full stop).
