I have been involved in a long running "discussion" (as I will call it) with an acquaintance who continually tells me how great his Nikon D500 is vs the D850 I shoot. I have yet to see any of his "great shots" while he has seen numerous shots from my D850, especially shots taken at night, with several of those same shots printed at 16" x 24". For me the proof is always on paper.

An amateur will tend to believe hard work is what brings good luck and success. Professional photographers know the secret is a full-frame camera.

frequently yes, this wouldn't be the same lens but often I have no choice. if looking at birds or say, sarafi in kenya...there is not time to change lenses, I get what I get and crop. As for framing the same with a full fram vs crop...on birds? And insects...they don't hang around still quite long enough. I have asked them nicely, but they still do what they darn well please. The flowers do hold still but what is between me and a bloom also leads me to be further away at times and needing to crop.

wrong thread posted to...but cannot delete. sorry guys

You can <edit> for about 60 mins and just change to <deleted>. You'll see other making this correction sometimes.

You mean all my hard work, reading and learning, sitting still by the tree the birds favor or watching the flowers twice a day until the bloom is just right will produce lousy results without a full frame. Well, oy vey iz mir . (Oh woe is me)

I shall immediately rid myself of my canon 80D in favor of a MArk something or other and stop working so hard.

Who would have thunk it...less work...no learning..better pro quality results. I can give up being a doc and go into studio work! ?

When you know you need a full-frame camera, you have the knowledge to succeed.

I know that the more pixels you squeeze into the same area, each pixel gets smaller and at some “smallness” or other, you start to get an increase in noise.

Obviously, a full frame camera has more pixels just due to the larger size.

I shoot a cannon 80D crop sensor.

Keeping this all in mind my question is.

When I shoot with the same focal length on crop vs full frame and then crop my final product, it seems logical I need to crop less close with the smaller sensor than the larger sensor to get the same ultimate size since the same, say 50mm lens, is effectively longer on the crop camera getting me closer to my subject. Because of this full frame envy and pixel envy aren’t all they seem to be?

Yeah, I have full frame envy but to be honest, I get pictures I like with my current camera but the above question has just always bugged me and figured a few in here can provide an answer. I still want a full frame but want to learn more tech details anyway. Also partially my effort to learn and understand pixel's better.

Keep in mind that a 50 is a 50 is a 50 regardless of the sensor format size. The magnification is always 50. S0, the 50 doesn't get you closer. The main subject will be exactly the same size on the sensor with the same lens at the same distance.

I love my 80D. I have a f2.8 70-200L and a f4.5-5.6 100-400L which both fill that crop sensor with mind blowing tack sharp detail.

All of this hot-air-blowing is because you have a flawed assumption. You are assuming that the same lens will always be used on both FF and APS-C. Don't you remember what you sixth grade teacher told you happened when you assume?

And all that "extra light that is thrown away" isn't exactly worth its weight in gold. There's a reason that camera manufacturers make FF lenses and APS-C lenses.

I have to do some research but I think the amount of light that you throw away by using a FF lens on an APS-C camera is indeed worth its weight in gold if not more.

A pound of luck isn't worth half as much as a full-frame camera.

No one needs a constant flow of drivel, either.

Why is the assumption flawed?
when describing a physical event, it is customary to limit the variables to the single variable being examined. This is customary in science, even if not in the 6th grade. Also, people who have both full frame and crop sensor cameras often use their full frame lenses on their crop cameras, and vice versa for their full frames that have a crop mode.

Ah, Cat, you are in the wrong forum if you feel that way.
