I've found some in my boat and keep asking myself the same question over and over..
The lens lineup for FF makes so much more sense to me. I do have an opportunity between now and this weekend to return the 40D and 35L I just picked up for a new 5D and a 50 1.4.
I do shoot my kids sports and can appreciate the FOV in favor of the crop. Until sports start again in a few months, I really like the 50-ish equivilent lenght for indoors of my 2yr old. I wouldn't be able to pick up a crop and the long lens I'm still missing at the moment yet anyway.
Anyway, my point is this - I've read the 5D vs 40D threads and it seem the majority here lean towards the cropper for the ~2 years of tech and very good IQ out of the 40 (as of this point in time). Aside the 40D seemingly "winning the poll" and considering the 5D is going to be upgraded soon with a feature set that I would assume comparable to the 30-->40D improvements..
Would right now, today, be the wrong time to invest in FF? Wouldn't that be similar to going out and purchasing a 30D a few weeks before the 40D hit the shelves?
Personally, I think this 35L is wicked. I liked the Sigma 30, but I was one of the bunch that just got funky focus with it. I don't care for the IQ of the 28.. and I want a damn normal fast lens!
For me, I have a day or so to figure it out. 40D+35L, 40D+17-55, or FF now for new cheap and a 50 1.4. Those are the options I'm willing to consider at this point in time. Also, knowing I could actually add a 24-105 focal length sits real well with me.
?
