For those that have both and forget the web site reviews, what has been your experience with the 40mm and 50mm in real world use?

Do you find that the 40mm is just a better lens and has better iq or that they are pretty much even?

Sometimes with the review sites, you may see 4 or 5 comparative images, but that's not the same as shooting day in and day out with the same lenses.

You know, I started with the 50mm f/1.8 on a crop - perfectly sharp, clear pictures. When I went to 5dii, I replaced it with the 50mm f/1.4 - that lens never disappoints. Recently I sold the 50mm f/1.4 and replaced it with a great deal on the 40mm. I am just not into it. The light seems to fall off and it vignettes, I know it can be fixed in Lightroom. But neither 50mm ever had that problem. I am just not smitten with this lens. Maybe in time.

I have them both and I'm not crazy about the 40 either. I pick my 50 1.8 over it always. My 50 feels lighter but the 40 has a better build. I only bought it to use with my sl1, but somehow it's gets left behind bc I prefer the 28 or 35. It's a nice lens for video but I plan to sell it bc 40 on a crop doesn't work for me. IMO you just can't beat the 50 1.8 image quality over the 40. The 40 can't even compare > 50 1.8= better blurred backgrounds, has 1.8 aperture, lighter and it cost $100. The 40 = better build, aperture is only 2.8, smaller and cost $150-200. No comparison IMO.

I've read that and seen that on a couple of reviews. However he had a side by side comparison of the same shots on a crop and FF camera. Same lens, same settings.

For those of us with a crop sensor it is a wonderful lens, and for full frame it does not always vignette.

My Nifty Fifty doesn't focus nearly as well as the 40 and it is louder when it focuses.

I used to own the 50 f/1.8, and never liked the lens. It was not sharp unless it was stopped down, and the auto focus performance was terrible. I currently own the 40mm pancake, and really like the lens. It is sharp wide open, and the AF performance is worlds better than the nifty fifty. The pancake is a great small, low profile walk around prime for me. The focal length works well for me on a full frame body. It's small enough to fit in my pocket -- or takes up almost zero space in a camera bag -- when I want to bring it along as an extra lens, too.

For the price I paid (less than $120 for a refurbished lens), I think this is one of the best bargains in Canon's lens lineup.

the pancake is going for 129 at BH and adorama.... no brainer at that price. Super sharp and tiny. Too bad it's not F1.2

I have the 50 1.8 Mk1 & 35f2. See no need to pick up something in between that is a stop slower. The size difference is non issue for me as well as the 35 & 50 are both small & lite. Saving an inch and a couple of ounces (if that) has no advantage in my mind.

I don't have the 40 but I have the 50. If you are shooting video, i think the 40mm is better since its STM. the 50 will be noisy.

The 40 STM is not silent when focussing!
It's quieter than the 50 f/1.8, but don't expect it to be anything like level of silence you get from a USM lens.

Oh ok. when I had the 18-55 STM it was virtually silent. More quiet than a USM lens. It could be your pancake is faulty? maybe not all STM lenses are created equal.

There are plenty of you tube videos showing the noisy 40mm STM.
Here's a couple that show it quite well...

STM does not indicate silence. It just allows AF during video.

I've had both and prefer the 40 over the 50 1.8. Better build, more accurate and quieter focusing, sharp at 2.8 and a great go-anywhere lens.

Thanks for the Videos

I thought STM (Stepper Motor) lenses do indicate silence (obviously not ninja silent). Just to clarify, any lens can autofocus on video, STM lenses are just more efficient at it.
