Stop this crop factor / equivalent focal length nonsense

Better, and easier....just switch to full frame. Then and all confusion ends....until you upgrade to a digital medium format, digital large format, or whatever.

I like the idea of Angle of View and Field of Vision as a way of understanding the result of putting a lens designed for a full frame camera on a crop frame camera. I've been struggling with this myself and have found that I cannot get the field of vision I want with a full frame telephoto lens on my Nikon 7200 DX camera with 24 megapixels. Looking at the crop factor which would give me a 450 mm view means nothing when the field of view is too small to capture the picture.

“Oh really” Are you trying too make some sense or being funny!

That is exactly my conclusion. I'm going to switch to a FF camera for some of my photography.

Well said. I haven't visited this site for about a month now. I think I'll make it two months before I try again. I know I will get nasty remarks for saying that. Hoping for more humility and civility on this site and in America in general.

Personally I hate the term "crop sensor" since ALL sensors are crop sensors - yes even medium format. The rectangular sensor is always cropping the circular image projected by the lens...and then one person's "full frame" is always someone else's "crop sensor" - from the tiny smartphone camera sensors, to M4/3 to APSC to FF to MF. (side note - Personally I think all sensors should be SQUARE which would eliminate the need for vertical grips....just crop the image in camera or in post as needed.)...some day we may have 8x10 sized sensors - never say never just look at the jumbo trons in Times Square.
As in the film days we did not call a 35mm film SLR a "full frame" camera - we simply called it by the size of the image or designation - "110", "135", 35mm, 4x5, APSC, 5x7, 8x10, "645", etc. But as someone else mentioned "good luck" with that! I think the term "crop sensor" will be around a long, long time unfortunately and the confusion will continue along the way with "equivalent FL"... to me I just chose the lens to suit the subject and judge everything else in the viewfinder - three cheers for 100% VFs.

Doesn’t a square sensor crop the circular image from the lens too... Isn’t a square just a special type of rectangle...

Many of us do. Besides we have the choice to write it, read it, or ignore it. Just happy we have a place to agree and disagree.

In that respect, even a 35mm film was cropped.
Seems a bit persnickety.

WTF does it matter? It's minuitae and not worth splitting hairs over. If the image is good, that should be it. If the lens is exceedingly wide or especially long, then yes, it might be of value. But otherwise, who really cares?

This may work best for you, but to suggest that it will work best for everyone is a pretty big overreach.

Fully agree !
If you cant master by physical use in a very short time which of your lenses to use on whatever camera you own for the subject and framing you want there's little chance you are going to get any value whatsoever from something being given a different naming.

Well said. Folks way over-think stuff that has virtually very little affect on what you see in the vf.

I agree with you Chris in fact the sensor that is supposed to be full frame is not really a ff if we’re going by 35mm (36x24) standard a digital FF would be at least that size don’t you think oh well 1mm less big deal I guess who counting a hair here or there! Just my 2 cents....
