The perfect "walk-around" lens

Takes sharp pictures for the price



Quick focus, great low light performance.

Joe from Brookline, MA on 1/28/2017

Crutchfield Customer Review (What's this?)

You can't beat this as your main walk around lens on a crop sensor camera. Paired with my T6s this thing is unstoppable. The low light performance is even better than I imagined and read about in reviews. LOVE IT!



24 mm pancake

Steve N. from Pittsburgh, PA on 7/16/2016

Crutchfield Customer Review (What's this?)

Great small lens. Work really well with my SL1. Easy to carry and works really well for all uses. Takes sharp pictures, day and night, the speed eliminates the need to use a flash. The size and light weight make it easy to carry - great for street photography. Highly recommend!

Pros: Speed, size, value for the price, solid feel.

Cons: None.

Great Lens!

Crutchfield Customer Review (What's this?)

When comparing this lens to the EF-S 50mm f/1.8, I like this lens a little more on a crop body because it is similar to a traditional 35mm lens [actually 38.88mm for T3i]. It makes it a little more useful in just walk around picture taking. The build quality and STM are also better. Overall, this lens performs to my expectations, although, perhaps not as high as professional photographers, but for quality and value it is hard to beat. As long as you have reasonable expectations, this lens will probably surpass them. Also, for video this lens performs well also. Looking forward to having more fun with this lens!

Pros: Overall Value Nice, sharp pictures Much less motor noise than 50mm f/1.8 Small pkg and lightweight Nice walk around lens

Cons: Not much room for fingers, but it's a pancake lens, so expected Might only be my example, but interface to T3i camera body seems overly tight, almost to the point I thought I was installing incorrectly

Pancake hooked!
