Sharp images with a few downfalls While my planned images (nighttime photography, posed shots) were always crystal clear, using this lens during an event can range anywhere from awesome to frustrating. The autofocus is loud and unreliable in low light, but get outside or in a well-lit area and you're golden. This lens is light and wonderful for street or interior photography, not suitable for portrait photography unless the distortion is fixed in post.
Great little wide-angle prime This is an oldie but goodie. Pretty sharp (for a wide angle) and surprisingly quick to focus. Yes, it's noisier than a USM or STM lens but it's no worse than a kit lens. Feels quite sturdy with a metal mount. Gives a very useful 44mm equivalent view on a crop. You may wonder why you would get this lens for a crop rather than the EF-S 24mm f/2.8 which is smaller and a little sharper. Simple: this is a true EF lens that will work on full frame or crop body. I use an APSC for now but plan to upgrade to FF soon and didn't want to make my lens redundant. This can be a true wide on FF or normal on crop. If you're committed to the APSC format go with the EF-S 24mm. This makes a better walking-around prime for a crop body than the popular 50mm f/1.8. True, the 50mm performs better in general but the 80mm equivalent view is rather useless for anything other than close portraits. This lens is better for street shots and group portraits.Read full review
Good value lens. The lens is a good value in all respects. The infinity focus is very handy for night sky photography.
