I would say Yes. Right now is the best time to load up on Canon lenses. I have not seen price as attractive as from B&H Photo Video for example in the past year. I just got two "L" lenses in the past few weeks due to these great price and I am finding it very hard not to get a few more as the prices are likely lower then they will be for the rest of 2012 (at least until next Xmas).
I mean, I got the 70-200 f2.8L IS II and the 35 f1.4L for a total rebate (both lenses) of ~$600-$700 compared to their prices during the summer. So any lenses I plan on needing in the next 6 months, I am trying to convince my wife they would make great Xmas gift! - lol
B&H price combined with the current rebate the 70-200mm 2.8 IS II lens is $1000 cheaper here. That's a bargin! I really wanna get a 50mm, but I enrolled in my photography course today and was gobsmacked at what the fees were like- $10,000 for the first year. Not including materials. And they're forcing us to get a FF camera, I'd get a grey market FF camera since the 5dmkIII wont be released in the first half of next year.
I tested both the 1.2L and 1.4 50mm lenses today (city camera house) and they're selling the L for $2000 I asked if he could go cheaper and he said a "great deal" that he offered was $1980. That's $20 difference, WTF! 1.4 = $585 and sima 1.4 (which wasnt available to test out even) = $525. These rebates are tempting me.
But one of my future teachers said that when went start in feb he'll talk in detail about getting "great deals on cameras, flashes, light metres and lenses". I highly doubt they'll be cheaper or if come close to internet/overseas prices. DO I wait til Feb or do I just buy the lens now?? I dont *need* it at all, I just want it lol
