I am a wedding photographer and I already have a lot of great gear that helps me do my job well. I have a 1DX, a 5D3, 70-200 f/2.8L IS II, 24-70L II, 85mm 1.2L, 50mm 1.2L, 100mm f/2.8L IS Macro, 90mm f/2.8 TS, and I just picked up the 300mm f/4L IS. I obviously have everything I need to do a good job at any wedding, however I just like to buy gear and get the best I can as long as I can justify buying it. Sure it would be really nice to have the 400mm f/2.8 for when I am stuck in the balcony of the church but I can't justify the price of the lens for that reason.
I am so close to buying the 200mm f/2 but I am actually having a hard time justifying the price. I have looked into it so much and I know it is superb, but will it be worth the $6000? I don't know? I love to shoot wide open and I love lens compression. I shoot with the 85 at 1.2 always and I try to stand back and use my 70-200 at 200mm or sometimes I even use the 300mm for portraits.
I also like the 300mm for when I am stuck in the back of the church during ceremonies, but I would probably have to sell it if I picked up the 200 f/2. I am curious how the 200 f/2 would preform with the 1.4xIII or 2xIII teleconverters in terms of IQ in relation to the 300 f/4L. I am not terribly concerned about focus speed because the 300 f/4 isn't super fast and I mostly use it when everything is still.
Anyone have any thoughts? Especially those of you who use the 70-200 f/2.8L IS and the 200mm f/2. Also if by chance any of you have any knowledge on how the IQ of the 200mm f/2 with the 1.4III teleconverter relates to the 300mm f/4L?
