Will there be any significant performance with FX lenses vs. DX lenses on a D300?

Recently upgraded and acquired a D750 body and presently researching for FX lenses. I have a D300. Will full frame lenses be an improvement/advantage on the D300 versus lenses designed for DX format sensors? Thinking about trading in & up for FX lenses to consolidate.Your thoughts/opinions,thanks.

Probably not, but they will work fine. I have a D750 & a D7100 and have nothing but FX lenses

The greatest amount of lens distortion and other issues occurs at the outside of the lens elements. DX lenses are sized for DX cameras so 100% of the lens issues will be evident in your images. With FX lenses you are only using the center 2/3's of the image presented by the lens thereby avoiding the vast majority of lens issues around the edges. Definitely a positive development. PLUS, should you ever upgrade to a full frame camera body the lenses will still cover the entire sensor.

The effective focal length will be 1.5x the focal length of that particular lens..So if you have a 50mm FX lens, it will simulate a 75mm lens and give you the angle of view of a 75mm lens..The image it produces on a D300 which has a DX sensor, should be very sharp, as the camera will be using only the central portion (the sharpest area in most lenses) of that lens.

ANY lens on that body needs the 1.5X crop factor applied to determine an equivalent field of view.

Generally, FX lens are a better, more expensive Professional level build in their own right. Will this translate into better images on the 300? The lens will deliver more than the 300 is capable of recording, but it won't hold you back either.
AND FX lens are forever lenses... you will hold on to them to your next body upgrade for the foreseeable future, so they are a good investment.

I do not think the D300 sensor is good enough to differentiate between some of the latest DX/FX lens IQ's - though IMHO, FX generally holds an advantage among the latest designs when you are able to perceive it. The biggest differences may be in size, weight and price.

I don't find any empirical evidence to support that. Can you post where you got that or did you just make that up. Tony Northrup posted a video on this very issue from information found on DxO labs. The findings are that it is better to use crop sensor lenses on crop sensor cameras. DxO Labs has consolidated information from the standard MTF graphs for lens performance into the what they label Perceptual MPix or P-MP for sharpness. The higher/better scores are rendered when the crop sensor lenses are on crop sensor camera and not when full frame lenses are on crop sensor cameras. Another member has provided you a link below. I noticed you did not respond to it.
To suggest otherwise, you need to find another technical lab to validate.

The logic behind MT Shooter's comment is irrefutable.

Gee, more idiot remarks from our resident moron. What a surprise. Haven't taken that remedial reading class yet I see. Go away and take your incompetence with you.
As for proof, it's called MTF Charts. Check them out if you ever learn to read anything.
