I have been wanting to put this to the test for so long, cause I got tired of the 1.5 crop factor "you get more reach" argument... "A 50mm acts like a 75mm, it is longer on a DX body" comments... Essentially you are using a smaller sensor when using a DX camera, thus getting a smaller image. Granted you get more pixels per square inch but my point is that you are losing out in the end. This said DX isn't bad ... it just isn't what I thought it was... You do not get more reach with your lenses you just get a smaller sensor on which to capture the said image. This is an FX picture with a DX cropped added to it... See what I mean? Maybe not... Okay here is the FX picture View attachment 248773 Versus its DX counter part size for size compared to sensor size I call it the "real DX" View attachment 248774 Of course the same resize as the FX shot above leads you to think it is closer to you but it is not. I was at the same distance with the D3 and D300... View attachment 248775 You just lost all the shaded area View attachment 248776 Now the DX crop on the FX camera and you have the same image View attachment 248777 Well ... Same results... I used a 50/1.2 on a D300 and a D3 to show these and ... Well... That 50 did not turn into a 75mm on the DX... It stayed a 50, it did not give me more reach - it actually made me lose a whole big area that the lens covers... Why do I like FX... It just makes me use my lenses at 100% capacity as opposed to ... well you get the idea but for all of those who love the cropped sensor I saw this today and though of you :wink: View attachment 248778 Kidding aside the real difference is in the sensor size, don't give me the "you get more reach because of the crop factor..." no... gime "I get less coverage and that's fine by me because when I crop I get more pixels left over" then we'll be speaking the same language. View attachment 248779 So your 200mm lens is not a 300mm lens all of a sudden cause you shoot DX but still is a 200mm you just have less to work with, any questions? Again.. DX crop on the FX sensor and DX View attachment 248780 View attachment 248781 And FX View attachment 248782 Which would you rather end up with... ? Mind you I had no tripod but not move from where I was sitting.
