You can use any Canon EF or EF-S lens with the 400D.

Re: EF lens on canon 400d?

Canon's camera models which use the APS-C sensor place the sensor in exactly the same position as Canon's full-frame cameras.  This allows compatibility with either type of lens on the same camera body (with one catch).

 

 

Full frame cameras have sensors which measure roughly 36mm x 24mm.

APS-C sensor cameras (such as your 400D) have sensors which measure roughly 22mm x 15mm.

 

The EF lenses are designed to produce images large enough to completely fill the frame of a full frame sensor.

The EF-S lenses are designed to produce images which are only large enough to fill the frame of an APS-C sensor, but NOT a full-frame sensor.

 

This means the APS-C camera can use any EF lens... in addition to the EF-S lenses.

But you can't go the other way... you can't use EF-S lenses on a full-frame sensor camera.

 

For your 400D, you can use:

- any EF-S lens

- any EF lens

- any TS-E lens (the tilt-shift speciality lenses)

- the MP-E (specialty extreme-macro photo lens)

 

But you cannot use the EF-M lenses (these lenses are designed for Canon's "mirrorless" bodies).

Most of the EF lenses, if not all, will produce better images on your camera than EF-S lenses do.  This is because you are using just the center of the EF lens.  This is where most, if not all lenses, are at there best.  Will you need to become a 'pixel peeper' to see or notice this, most likely you will ! Smiley Happy

This is an outdated 'fact'.

 

Modern STM EF-S lenses will give you better image quality than most consumer EF lenses, and match the image quality of older L lenses. 

 

There have been huge advancements in lens design and manufacturing in the last 10 years.

I am not buying that until you produce a MTF chart to prove it.   I'm waiting! Smiley Wink

If you got off your porch you wouldn't need an MTF, you'd know it was true.

Oh, you silly man, you know you have one or some, I mean.  C'mon on and share, I know you have them memorized by now.

You know you want to. Do it.  You'll feel better when you do.

 

Ya, know all those steps on the deck (not a porch) and those, way too, heavy "L" lenses are just too much for me.  I need to trade them in for some plastic STM's so I can be just like you. Smiley Happy

Sorry, simply buying STM lenses won't help. When will you learn that buying tons of gear doesn't make you a good photographer?
