Alternative: Sigma 85 f1.4, use the savings to take your significant other out for a night on the town, pocket the rest. Enjoy your bokehs and extra dollars
I was seriously considering jumping on board with the Sigma 50 art... and then this came up and I was like, Sigma who?
I've never cared for after market manufacturers... mostly because their products depreciate significantly faster than Canon gear. I hate... HATE... losing money on gear that I bought regardless of whether I bought it new or used...
I have a formula... and I've shared it a few places... so this isn't anything new.
If you pay X for a lens, use it for a few years (Y), and then sell it @ Z, then the cost of owning the lens is (Z-X)/Y= cost per year. I realize there isn't a noble price in mathematics in my future, but if I buy the 85L, I should be able to sell it for around $1600 in 3... maybe 4 years... and therefore the formula works out as such:
(1600-1440)/4= 40 bucks a year that I am GETTING to play with the lens at my leisure. So it is not only a free rental... but I get a little back on top of it as well.
And I do this with all my gear. The bodies... as all of us do lose the money money for us. It is the cost of admission to this wonderful hobby that occasionally makes us a few bucks. My golf game on the other hand... never made me a dollar... even with side bets for beer.
So I'm digressing... and I'm sure the sigma is a fine piece of glass... and if I bought a used like new one I could probably break even as well... but if all I'm doing is breaking even, I might as well get the king of the 85's... and that title at the moment belongs to Canon.
