I am frustrated by the gap in the Canon L series tele-photo zoom lenses. Photography is purely a hobby and the budget is a consideration. I have a full frame body, and although lens speed is important, that is secondary to lens weight (on the longer end) and the budget.
In most respects Canon does a great job offering L series for the pros and the "poor-boy" geeks like me...until we get beyond the 70-200L series. Kudos to Canon for offering a wide array of 70-200 options.
Basically I'm left with two options for more reach. The 100-400L is a quality lens but long in the tooth (and rumored to be replaced for some five years now) and has other drawbacks with weight, push/pull barrell, and variable aperature.
I think most would agree within reason that the 70-300L is compact, very good quality, and price apporopriate. However the 4.0-5.6 variable is frustrating in the sports arena (especially indoors). Somewhat frustrating is the reversal of the zoom and focus rings. But most frustrating is the incompatibility with a teleconverter for that extra reach.
In an ideal world, I'd like a 100-300 4.0L that is compatible with the 3rd generation teleconverters (even a 150-300 would be acceptible to hold price, weight and maintain 4.0 lens speed). No doubt it would be a little heavier and a few more bucks than the 70-300, but lighter and smaller than the 100-400, and it would be a great alternative to the current offerings.
I'm a rookie on this board, and I'm wondering if I'm just a lone wolf howling in the distance, or is am I a part of a herd that needs to start growling to prod Canon to expand their lineup in an overlooked area?
