I as well own both. the 40mm is my general purpose do just about everything lens though if I'm looking to get portraits out of the deal I swap to my 50mm for it's equivalent FL on my 50D. I'd say each has their uses. the 50mm is useful for portraits on crop and the 40mm is a great general purpose walk around prime. I figure for the prices of each (can buy both new for <300 in Canada) you might as well own both as they'll both find a use if you're a crop shooter. If you're an FF shooter then I would say the FL's are really too close to make it worth it and in that case I would go with the 40mm simply due to it's better sharpness wide open and better build quality as well as faster and for my eyes more accurate AF

The camera is just a tool - it is not responsible for the picture.

You find the focal lengths too close for FF but not for crop? Whatever camera you have, the quotient is still 50/40 = 1.25.

the equivalent FL's on crop are basically 20mm apart whereas on FF they are half that. That's my logic on the issue

The equivalent focal lengths on a crop gives the exact same percentual difference in magnification or field-of-view.

It is irrelevant to consider the difference in "mm" - it is only the quotient that matters.
500 -> 510mm is tiny - 510/500 = 1.02.
10 -> 20 is huge - > 20/10 = 2.0

So no - when you move from 40 to 50mm on a crop camera, the captured image will represent a 80% crop (but a 25% extra magnification) of what you captured with a 40mm lens. And the same thing happens when you move from 40 to 50mm on a full-frame camera.

Completely agree, for the price of the 50mm and the 40mm, it is a steal to have both at your side, both of which used for different purposes. Glad I got my 40mm 2.8, wonderful lens.

I loved my Sigma 50mm f/1.4 EX DG, and I could never get used to the Canon f/1.4 & f/1.8 build quality. Here's an image of the Sigma f/1.4 next to the Canon f/1.4:

Sadly, I gave my 5D MkII with the 50mm to a friend for a wedding gift, so I no longer have it, but I DO have the 40mm STM and really like it!

Hello guys,

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.

Thank you

Heya,

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.

Very best,

Thanks MalVeauX for the advice...

I wish I could buy more lenses to try it on... but the case is that I live in Brazil, and here everything is so expensive that denies me to try a wide variety of lenses... So I have to take the moment when someone, or myself is in the USA to buy one of those. That is the case right now... a friend of mine is going to bring it to me, as he is in the USA right now, and I was thinking of use this thanks giving moment to buy cheap stuff...

So, the doubt is between this two lenses... if you would pick one of those first, which one would it be?

Thank you

Heya,

I got the 50mm 1.8 first. I you've never used apertures that wide, it's a big step in learning how all of this comes together, at least it was for me. F2.8 compared to F3.5 wasn't a big step in learning how to do certain shots. But F1.8 really made me re-think how I do the shots.

I would get the one that best suits your needs.

If you're just looking for a sharp prime with a wide aperture for learning and experimenting and fun, the 50 f1.8 is a good choice.

If you're looking for a walk around lens with better autofocus for random shots and just general small and light, the 40mm f2.8 is a good one.

Very best,

I would suggest the 40mm 2.8.

Its mora accurate in focus, has a bit wider Field of view, its even sharper then the 50mm.

The 50 1.8 is extremely sharp, if it focuses properly... Sadly that is a BIG "IF".
Also because the focusing is not reliant, you will not-too often use it wide open, and below 2.8 anyway, so for me the 40mm 2.8 is the clear winner.

+1. Get the pancake... later if you really need wide aperture, save money and get an f/1.4 lens.
