I need an advice.
I am quite new to the DSLR world, and I bought in April 2013 a Canon T4i with the 18-135 lens kit...
I am still learning many of the features that the camera offers, and I am thinking in buying one prime lens to try it out and feel the difference. Everybody tells that you need at least one prime lens to use, as it offers another insight of shooting.
But I don't know for sure which one, the Canon 50mm 1.8 (nifty fifty) [$110 at Amazon] or the Canon 40mm 2.8 [$149 at Amazon].
Which one is the best for walkaround photos and portraits, if it is possible to combine both styles.
Both are incredible values. The 50mm 1.8 gives you more options when it comes to wide aperture. The 40mm gives you better focusing. Their focal lengths are very similar, so it's not a big difference there unless you're super nit picky about how far you are from a subject when framing. But honestly, squabbling over 10mm is just not worth being concerned in my book. I would focus more on the features: aperture, autofocus quality, build quality. The 40mm will probably last longer just based on build quality. Both are very sharp lenses and high quality optics, with a cost that just screams budget, but as any good photographer can attest, very good images can come from ordinary equipment.
To me, it comes down to aperture the most. Both are light weight and pretty small lenses. Both are sharp. Both are not the highest in build quality. The 40mm is probably better built, it's smaller, and focuses a little better, but costs you some aperture (f2.8). The 50mm bigger, has a little more issues with nailing focus, made completely of plastic, but gives you access to wide aperture (f1.8).
Frankly, I'd get both and try both and send back the one that you use the least, or sell it, etc. It's worth trying both since they're so inexpensive and they trade/sell quickly for the same reason as people wanting to try them.
They're always in the for sale board, at lower than MSRP costs, so you can try either of them and sell or trade them away if one doesn't do what you're after.
