The original poster was speculating on why NOBODY makes such a lens, not why Canon doesn't...Most people with SLRs don't get another lens to complement/replace the kit lens.
sorry but if this argumentation would hold it´s water then any lens beside a kit lens makes no sense for canon.
and canon would not have sold... how many... 90 million EF lenses?
Yeah, 90 million EF lenses for 70 million EF cameras. How many lenses, on average, is that?
Or, perhaps Canon has done the research and found that there isn't a market to make it profitable for Canon. Buy of course, you know more than Canon, so Canon should do your bidding, eh?
Canon makes a 300 f/2.8 for close to 7k. And you think Canon will make a 600 f/5.6 for 2k? My guess would be that it'll be closer to 7k, like the 300 f/2.8 IS II.
The 90 million EF lenses for EF cameras are Canon numbers... Since we are talking about "anyone", you have to add in the Sigmas and Tamrons of the world to the total.... Even if we were insanely optimistic and said that Sigma and Tamron sold 50 million EF lenses (I doubt it was half of that), you get 140 million lenses to 70 million cameras, or one extra lens per camera.
And six months ago, If you told me that there would be a $1500 600mm zoom lens on the market with good quality images I would have laughed at you..... and six months and $1100 later I was wrong.
I believe that it is possible to make a 600F5.6 lens for $2000. What I don't believe is that there would be a good market for it... Those who must have the very best will go for the $12000 Canon, and those on a budget will go for the $1100 Tamron zoom. This really pinches the market... but there is no way I would place bets on this... Who knows what Tamron and Sigma have up their sleeves....
Yes, thanks for the correction; he did mention EF so that does include 3rd party manufacturers. I got a little peeved when he called me out when I said that most DSLR users tend to have 1 lens/body.
So if the real number is about 1.5 lenses per body.... that would mean half the bodies with 1 lens and half with two.... or 25 percent with 3 lenses and 75 percent with 1.... However you slice it, there are a lot of cameras out there with only 1 lens, and this goes to prove one of the things I have been saying all along... we are not normal and do not represent the typical camera user.
