Best 'Excuses' You've Used to Convince Your Wife to Get a New Lens....
hmm let me think
i believe it was "you have to shoot this wedding, do it right, and buy the bloody thing (24/70 f2.8L) she spent three days on the phone, trying to hire one, and had resigned herself to using my rather average sigma 24/70, on the way there, she was telling me she was a little worried about the quality of the lens (i have no trouble with it, but she thinks its a bit soft) so i told her to shut up, go and buy the L
Last lens i had to convince her i needed was the sigma 10-20mm, excuse was something along the lines of "its my tax return, im going to spend it on an ultrawide"
my wife being a wedding photographer makes it a bit easier, in fact we dont argue about if we are getting new lenses, just what they are going to be.
