Isn't that the truth! Just when I think I have a clue, I realize I don't! Not to jump in on the OP post, but how can a macro lens be a prime lens? I've seen that mentioned several times.
(not saying that isn't true, but doesn't make sense to me)

A prime lens has a single focal length. Why can a true macro not be a prime?

Anand,
I'm still very new to this, wasn't disputing the statement, my lack of understanding and wanting to learn, "made" me post. :)
Ashamed to say I didn't know a prime lens had a single focal length. That is the only requirement?
Thank you!
Andy

Sorry, I should have phrased that differently. How about, "A prime lens has one focal length, as opposed to a zoom lens. Most macro lenses have a single focal length, so they are prime lenses." :-)

The FOV Is Not Identical on the DX Camera. It Is Not Identical on the FX Camera. I have both of both and just went through the drill with both cameras and both lenses.
Craig

Because you are not testing a 35mm DX and 35mm FX on an APS-C camera. The 35mm FX would just spill the extra image projection off the edge of the smaller sensor.

In terms of focal length, & aperture, it is. Only it's made to project a smaller circle of light on the sensor. Using an FX lens results in the circle of light spilling over the sides of the sensor on a DX camera...


Doesn't light spill over the sides of all sensors since the lens "projects" round light over the sensor?

Yes it does, however, the smaller circle of a DX lens will not cover the entire FX lens sensor & thus you get vignetting of the corners, especially at smaller apertures. That is unless you set the FX camera to DX mode in the menu...

Ok, folks just ordered my new camera. Ordered Nikon D5300 along with Nikon 70 to 300mm zoom and 105mm Macro.

Trying to decide on prime lens. I have never had a prime. On my old D40X I just used the kit 18 - 55mm lens. I am trying to decide between Nikon 35mm 1.8 or the Nikon 50mm 1.8.

Any thoughts? Would there be much difference between these 2?

Thanks in advance.

I think there is a big diffrence in the 35mm & 50mm for you the on the crop sensor. the 35mm is a true 35mm and the 50mm gets croped to a 75mm in the D5300.
Craig

55mm f/1.8 G
55mm f/1.8 G...

35mm f/1.8 G
35mm f/1.8 G...

Sorry, that's 50mm f/1.8 G not 55mm f/1.8 G

Once again, I disagree. The 35mm is a true 35mm and a 52.5mm equivalent lens, the 50mm is a true 50mm and a 75mm equivalent lens. It does not matter whether the lens is a DX or FX lens. It only matters what the camera sensor is.

I purchased the 50mm f1.8 when I was using the D7000 primarily. It's a great lens, BUT, when trying to shoot things like thanksgiving dinners, etc., the field of view is too narrow (like a 75mm). Since you have a crop camera, I suggest the 35mm.

This is correct.
Craigfair has no idea what he is talking about.
And being as he apparently has the items in front of him and is doing comparisons - he also has no idea what he is looking at.

These example photos are either doctored or not taken with proper scientific methodology.

They are not taken from the same spot.
Are they taken with the same camera?
Are they taken with a D5300?

Could you repost and leave them uncropped and leave the exif data in?

I'll have to retake the photos and post because I posted the others right out of the camera
