REALLY need your advice. My gear: 5D Mark II, 85mm 1.8, 70-200 f/4 IS. I mostly use it to shoot my own children. I also occasionally do photo shoots of families, so would like a lens that can allow me to do a nice GROUP portrait. When traveling, I enjoy architectural photography and landscape photography. Added to it Sigma 35mm 1.4. Seemed like a good idea (someone once told me that increments of 2 were a good rule of thumb: i.e., if you have a 70mm, 35mm would offer a nice change of perspective, whereas 50mm may be a bit too close). But now I'm considering returning the 35mm: I find that 35mm distorts the faces a bit too much for my liking and I can't always step further back indoors. Unfortunately, I didn't really have a chance to test it outside much, maybe I would have changed my mind then. However, if I return it, I need to replace it with some other wide-angle/normal lens. WHICH ONE? Can't seem to decide. It seems that all zooms are out - not fast enough. Is Canon's 35L worth trying? Is there a chance there will be less distortion with it, or if I don't like the focal length, I don't like it, period? Naturally, I'm thinking about 50mm. I used to have 50mm 1.8, sold it when I got 85mm 1.8, not looking to buy it again. A friend loaned me his 50mm 1.4, and I have to say, I feel its quality is inferior to Sigma 35mm... Of course, its price is, too, so I'm not necessarily dissing it, but for my budget, I'd like something a little nicer. I also bought and returned Sigma's 50mm - it was waaaay back-focused, couldn't get any sharp images with it at all. So, I have a couple of questions: 1) Given that currently, my widest length is 70mm, what would those of you who have experience with both 35mm and 50mm recommend? Which one is more versatile? Which one is better for my needs all around? 2) Is 50L really worth it? What about back-focus? Should I try it? I really want a lens that would blow me away. 3) Would you advise to give Canon's 35L a try? Even though Canon's coming out with a new one soon? I feel like it'd be wiser to wait, even if the new one is more expensive, the prices on the old one are likely to drop, right? Problem is - I have a baby, so I really need something that would allow me to document his rapid growth RIGHT NOW, and not when Canon decides to make the 35L II. 4) Should I try Sigma's 50 again? 5) Or really, any thoughts on my predicament are welcome, especially if you have experience with different lenses in that range. Just please, don't say "get both 35mm and 50mm", I do hope to get both eventually, but right now it's not exactly doable. My window for returning the Sigma is running out quickly, I will try to return tomorrow, so any responses I can get tonight, overnight (from European posters) or tomorrow morning would be GREATLY appreciated, as I am at a loss. THANK YOU!
