The truth? We can't handle the truth!! (oh wait...that was Jack Nicholson...check that

Nikkor 50mm f1.8d vs f1.8g is there really a difference?

I am going to shoot the same sort of test ASAP...perhaps with a 50 series E and a 100 series E on DX and FX respectively or maybe a 85 on DX and a 135 on FX...hell maybe we should just do a 50 on DX vs a 50 on FX with the same distance and with different distances involved...
Can we see the EXIF on the original two shots please sir?

I can't give you the exif tonight cause I'm not home and don't have the originals with me on this computer.
But as I mentioned, both were done at 1/50th @5.6. First shot with D90 and 50mm 1.8 D and second with D700 and the 28-80 3.3-5.6 @ 75mm 5.6. Iso was 500 for both shots. This explains why the 75mm might be a little less sharp.
OK...can you do the same sort of setup except use the zoom on the dx set at 34 mm and the 50 on the fx...same distance same pictures as the original two shots you posted above??? I am curious what will happen...I know you are a busy man and charge lots of money per hour but photography is a passion sir! LOL

I'm a newbie and have just purchased the nikon 50 mm 1.8 lens. Could someone please explain the settings and markings on it for me.? I don't understand why there would be a lock allowing the rings to move when the shutter won't depress but on only one of the settings. I'm using the 5100 camera. And does the blinking dot in the view finder indicate that the camera is in focus? thanks!

I'll do it tomorrow. And might as well have more. But I will use a tripod and equal quality lenses so sharpness and distortion shouldn't give the answer away.
The difference is that if you were to use a DX lens on a full frame FX camera, the corners might not be covered or the quality of the corners would suffer a lot. The lenses (DX) are made to cover a the smaller sensor.
Ok, another one done on DX and FX. Sorry, no tripod and it was kind of impossible to match the frames exactly because one was a zoom and the other fixed. I tried my best to match the frames. So, besides the sharpness, just from the perspective point of view, can you say which one was DX? In photographic terms, perspective is called field of view (FOV). What I'm trying to show is that a lens that is 1.5 the focal length of it's DX equivalent will produce the same FOV.
I broke down and bought the f1.8d as the g seems to be out of stock pretty much everywhere (so did the d for that matter). I got this used and only three months old for $100 CDN. The girl bought it 3 months ago for $159.99 + she had bought a lens protector for it $27.99, which I also got, so with tax it was $212.42.
So now I have the 18-105mm and the 50mm 1.8d...
One thing I did notice about this lens...it seems to go on my camera a LOT harder than my 18-105? Is that normal...?

I get the same thing on my D200 and D40 cameras with my 50mm, so from my point of view, I'd say it was normal. I love my 18-105, too!
Top one is DX D90, 17-55 2.8 @ 2.8
Bottom one is FX D700, 55 manual focus 1.2 @ 2.8.
You probably see more detail in the DX shot because the shorter focal length + the same aperture you get more DOF, but the Field Of View is about the same.
Within this forum with the small size pictures, it is very difficult to evaluate quality and judge these things.
I'm wondering if lens curviture will effect the FOV since the Dx uses more iof the center of the lens than the Fx. Could there also be less distortion?

Hi Claudia. A 50mm lens is always a 50mm lens no matter which camera body it is attached to. However what does change is the field of view. A 50mm lens (whether it be the 50 1.8G or the 50 1.8D) is going to "look" like a 50mm lens when mounted to an FX body. However when mounted on a DX body lik the D7000, that same 50mm lens will have a field of view of 75mm. That is a 50mm 1.8 lens on the D7000 will show you the same field of view that a "75mm" lens would give you on an FX body like the D700.
Again, the lens is the same - it remains a 50mm lens - but it is the field of view that changes when using it on either a crop sensor camera or a full frame sensor camera. The Nikon crop sensor multiplies whichever lens you use on it by 1.5. If you are using a 200mm lens on the D7000 the field of view will be that of a 300mm lens on an FX sensor. A 200mm lens on an FX sensor body will give you a field of view of 200mm (no multiplier).
I know this may seem like semantics to you but I hope you realize what people are talking about when they say that a 50mm lens on a DX body equals a 75mm field of view on an FX body.
I own the D700 and D7000. I love the the 17-55 on my D7000. So when I bought my D700 I wanted something with a similar field of view. Therefore I got the 24-70 lens which gives me a very comparable view when I look through the viewfinder the D7000 and the 17-55 (which withe the 1.5 multiplier is roughly 25.5mm-82.5mm - close enough to the 24-70 lens.)
I'm a bit tired so I hope I haven't made things worse with my explanation! lol!
