As has already been said it is perfectly fine to use full frame lenses on cropped cameras. If you want ALL of what the sensor has to offer you need to understand that when using a lens designed for use with a cropped sensor you are using a lens that will cover the whole sensor area. When using a full frame lens it covers the center of the sensor only.

Other advantages and disadvantages have been already discussed.

You forgot to mention that on the full frame lenses the mounts are different when you use a APS-C Camera. I have a Sony a99ii. Cannot use the new Sony lenses on the market. They are E mounts for these lenses and the lenses that fit the Sony a99ii are A mounts. Totally different mounts. Only way l can get them to work is to purchase a converter from A to E Mount but I lose an F Stop in the process along with the photos not being full frame. They will be 3/4 frame photos. This is the only disadvantage you have using a E Mount lens on a APS-C mirror camera.
You forgot to mention that on the full frame lense... (show quote)


Sony FF and APS-C mirrorless cameras have the same E mount, so there is no mount issue.

What are the reasons against and disadvantages of using a full frame lens (e.g. Sony FE 24-105) on an APS-C sensor camera (e.g. Sony A6500)? I would like to use my Sony A6500 as a backup for my Sony A7Riii without having to buy and carry APS-C lenses on photoshoots.


The biggest problem I have with using FF lenses on my APS-C cameras is that my FF are all manual focus lenses from my film camera days with aperture rings which requiries me to make menu selections for each one when I put it on the camera. Also the APS-C lenses have smaller maximum apertures and less efficient in low light. To replace them with AF lenses would be very cost prohibitive for me. Bottom line, I'l stay with my current lenses and the inherent small problems and keep on shooting with what i have.

NO disadvantages, if fact, when using a FF lens on a cropped sensor camera, you are actually using ONLY the middle part of the FF lens, not the edges. Which should actually produce sharper images corner to corner than using the FF lens on a FF camera.
Advantage, cropped sensor.

Can't think of any disadvantages myself - at least, I've never experienced any.

Weight, size and cost. Advantages are better image quality, less vignetting, usually, but not always, better build quality and higher resale value. I just saved you a lot of reading.


A simple, strait forward, accurate answer is not enough on UHH.

Stay tuned for the rambling responses that will convince some readers to give up photography for a less complicated hobby.

I have used a Nikon 70-200 2.8 on my DX body Nikons mostly shooting youth/HS sports. Works fine and more light so faster shutter speeds.......


Nope, not happening, not without using a speed booster

"CHG_CANON" hit the nail on the head.
I advise if you do not have a full frame camera and getting serious buy only full frame lenses. As one they are generally better lenses (cost more) but, you will not have to replace them if or when you go full frame.

Other than the obvious narrower FOV and and some other factors already mentioned, IF the APSC sensor has a denser pixel array (smaller pixel pitch) - which in your case I believe it does, it will be possible for the sensor to make any lens faults - including limits of resolution more perceptible - so you may think the lenses' resolution looks better on the full frame and not as sharp on the crop frame - but using only the middle part of the FF image coverage may also , sort of, mitigate this perception.

More than half of my Nikkors are FF and all of my Nikons are crop sensor. Images are great. No disadvantages accept cost and weight.

You are spot on! I was looking to see who else might note that you don't have to buy all new glass if and when you decide to purchase a full frame camera. I wish I had followed that advice myself!

The smaller sensor gives a narrower field of view. If you can accommodate that loss then the FF lenses will give better image quality, for reasons already mentioned. It's at the wide end that you're most likely to notice the difference. If you want the same field of view that a 24mm FF lens gives on a FF camera you would need a 16mm FF lens on your crop sensor camera.

If you slow down and read this carefully, some terminology is reversed...

Actually the terminology is reversed anyway. You'll catch it if you read slowly.
