Your likes aside, aperture has nothing to do with it.

I think it's gonna be slightly heavier (close to the Sigma sports i think).Macoose said:Any ideas on the approximate weight for this lens?
Tamron 150-600 G2: 4.50lb (2010g)
Sigma 150-600 C: 4.25lb (1930g)
Sigma 150-600 S: 6.25lb (2860g)
I would think that Canon might try to keep it in the same range.
Just wondering.

Right. How on earth does aperture equate with whether a lens is telephoto or not?

Lee Jay said:Simple - there is a huge break point in the Canon lineup between lenses with apertures of 75mm or less (400/5.6, 300/4, 100-400, 70-200/2.8) and lenses with larger apertures (200/2, 200-400/4, 400/4DO, 300/2.8, 400/2.8, 500/4, 600/4, 800/5.6).
The most expensive lens under 75mm is the 100-400II, at $1,999. The cheapest of the lenses with apertures over 75mm (which are all over 100mm) is the 200/2 at $5,699. That's a huge gap (75mm to 100mm and $1,999 to $5,699). It is logical to place all the expensive ones, all of which have apertures over 100mm in the "super" category, while the others are not.
I wouldn't call the Opteka 650-1300 "super" just because it's focal length is over 400mm. It's $189.95 and basically just a piece of cheap garbage.

Aperture is irrelevant, cost is irrelevant, and your logic is "super" flawed. Incidentally, the 400/5.6 is a supertele lens.
But hey, you can call things whatever you want. You can use a 22-letter alphabet, start counting from 4, and categorize cameras by the number of buttons they have. Just don't expect others to agree with your 'logic'.

easy.... stack a couple of Vivitar teleconverters and it will no longer be super.....neuroanatomist said:Don Haines said:.... so with any lens, if you add enough teleconverters you can stop it from being a telephoto lens![]()

Yeah, but can you stop it from being "super"?![]()
Wow!AvTvM said:as long as tamron only offers zoom lenses with zoom ring turning the wrong way (nikon style) i will not consider their lenses at all, even if IQ were stellar and price rock bottom. it would be very simple and cause minimal cost to match turning direction of zoom (and possibly also focus) rings on lenses to the respective lens mount. only one cog wheel different plus lettering on lens barrel and/or ring. sigma has learned to do it (after many years).
i had tamron 28-75 and 17-50/2.8 a long tome ago. was ok with their iq, but sold them because of wrong ring turn direction. often lost shots in fast-paced moments, because my muscle memory was programmed for canon turn direction.
tamron's stubborn refusal to offer their lenses with ring turning direction matched to respective lens mount for market leading Canon EF/EF-S lens mount shows their utter disrespect towards canon users. it is wrong, it is inacceptable, it is stupid and it is punishable: with refusal to buy tamron lenses and by critizing their wrong-turned rings on every occasion. Amen!
