Normal lens on crop sensor cameras

What is a normal lens for Canon crop sensor cameras? I have full frame and now a 7D looking for a normal lens, what do you use for one?
Thanks for any information,
David

I'm using a 24mm on my Sony A6000 and a 35mm on my Fuji X-T2.
But really you should go for the focal lenghts you need instead of what other people use and the feel of "ought to have" so the question should be " I need a lens for this, with that angle of view........." etc

Start with an 18-135 STM efs lens or the 25-105 Canon lens. After you shoot for a while you will get a feel for what focal lengths you use most.

One could go back to the original 35mm film format to establish what is "normal." The film measured 36 x 24 mm and had a diagonal of 43 mm.

The 35 mm format, or simply 35 mm, is the common name for the 36×24 mm film format or image sensor format used in photography. It has an aspect ratio of 3:2, and a diagonal measurement of approximately 43 mm. So "normal" often was 50 mm for full frame. The equivalent field of view on APS-C cropped format is about 30 mm (50/1.6 = 31.2). Essentially this means that is you had a 50 mm mounted to a full frame body, and also had a 31 mm (if there was such a thing) mounted on an APS-C body, what you would see through the viewfinder of each would be very near identical.

"normal" just refers to not being wide and not being telephoto. That is typically thought of as a 50mm lens on full frame cameras, since your camera is a 1.6 factor crop camera, technically that would be a 31.75mm lens (31.75x1.6=50). There are 30mm lenses made for crop cameras that fit that description, their are also 35mm lenses made for full frame that would come close to "normal". Anything equivalent to between 40-60mm would be just about close enough to be called normal, imo

in the end it is what you like to shoot with. I have "nice" (maybe modern is a better word) 35mm and 85mm lenses for my full frame and only have a very old, fully manual, adapted lens to fit 50mm. It is just not a focal length I shoot very often.

I would agree that the 18-135 is a great "everyday" lens

There are numerous versions of the 18-135. Some are "great", some aren't so chose with care.

50mm is considered 'normal' for a full frame and 35mm (ish) is considered 'normal' for a crop.

But the fixed lens rangefinders came with focal lenghts from 35mm (a few) over 40-45mm (most) to 50mm (a few) and SLR's typically came with 50 (most) to 58mm (also quite some.) a lot of people ditched the 50mm and went with a 35mm lens often paired with either a 85 or 135mm

I have the 17-40, the 50's, 28-135 but they are all larger than I'd like. I'm thinking of the 10-22 but the 17-40 wide enough for me.
I guess I'd like a smallish lens of at least f2, I read about the 35 f2 but fringing and some softness turn me off on it. Does Canon make anything "normal" for the crops that is sharp?
Thanks,

I use a 28mm, or the 40mm pancake as "normal" on a 7D2.

The 40mm is long to really be "normal" approaching 70mm F.O.V.
Likewise the 24mm pancake is a tad wide. It frames similar to a 35/40mm lens on 35mm film body.

the 28mm is the closest to what a "normal" lens should be for a 1.6x APS-C IMHO. Offering a 44.8mm field of view, it's nearly spot on vs. the 43mm diagonal on FF.

The 30mmm are going to bring as close to a 50mm, which is the more "common normal" on 35mm film, but 45ish would be closer to "normal" than 50mm.

I was posting before I saw your reply above,
Both of the pancakes are very sharp, and quite good, but miss your aperture desire at only f/2.8.

The 28mm f/1.8 USM I use is quite old. It was a very affordable gem for years, but in today's focus on super modern glass, it has fallen from favor. I like mine just fine

"Normal" was considered 50mm during manual film SLR timeframe. It was the typical lens that came with a kit. There was also fewer wide angle choices: 28-35mm focal lengths were often a popular "wide" option.

Yes but that was actually later than the fixed lens 35mm cameras and the reason for 50mm was not it being considered the normal lens but because it was an easy and cheap design (2in)
