Having been informed that it had a crop sensor I started with these:

One of my pet peeves is the posting of photos to show the quality of equipment with only a 1/4 megapixel image.

Micro Four Thirds. Because the whole platform --- bodies and lenses --- is lighter and smaller than APS-C or FF. And the GH4 does a great balance of stills and video.

It's not a debate. It's an irrational shouting match! There is no reason to worry about someone else's choice. All the major platforms offer advantages and have disadvantages. Read reviews and choose gear for your needs.

Unless you are into the math behind the camera, your reply doesn't make a lot of sense. You can take great photos with both sizes of sensor. I have a crop and I process my photos and size them to any size I want - as you probably do with a full frame. Surely the choice is decided by the cost of the two types of camera.


The choice I made was really because of the factor of 1. I bought a DSLR and no lens. I use all the lenses from my film cameras and they work exactly like when they were mounted on the film camera. If I get a so call crop (which really I don't like the term) camera then all the lenses will work differently and no longer suitable for the type of photography I do.
If I were to buy all new lenses the smaller formats like M43 are actually better because I like a lot of DOF.

The biggest advantage of buying a "full frame sensor" is that you get a "crop sensor" with the full frame camera. Then you don't have to spend hundreds of dollars for a crop sensor camera!

A crop sensor also has the crop percentage applied to the amount of light that it receives. The f/stop of the lens has the same effect as the crop factor so the same lens will act a little slower on the crop.


Nope - given the same lens, the f-stop, light transmission and exposure is the same for either the FF or crop. Perhaps you're referring to the DOF?

They talked about both the DOF and noise. The reasoning is with the smaller sensor it has more noise so one has to reduce the ISO rating to have equivalent noise level. But well that the reason I pick the FF as there is nothing to think about.

A single question...
What is a full frame sensor???

Really?

Wow!

Owning models of both frame sizes I would say that for practical purposes (with optical quality equal) for the average enthusiast you would be unable to tell the difference in image quality unless you make prints in the 13 x 19 range or larger. I always thought it would be interesting to have a series of photographs taken in both formats and presented without the information of which size made which print and let the viewing audience identify the different versions based only upon their viewing of the print.
Owning models of both frame sizes I would say that... (show quote)



A while back I read (on the internet -- so it has to be true) that someone did just that with a number of professional photographers, but the print size was 11x14 (I remember the size because that's how large I print); they took nearly identical photos of the same subject using FF and CS cameras (including entry level DSLRs) and the pros actually couldn't tell the difference.

Really it's about the question Ron is asking. Why talk about Full frame and Crop. What's crop? What's full? But if you insist that there are such things then Full must be better than Crop right? And the factor of 1 is much simpler to deal with than any other number right?

While there are differences in your images there are other variables (lens and settings) that contribute as well. Would you be able to show the difference using one lens (same focal length, aperture, shutter speed, ISO) with the only difference being the crop body shooting from 1.5 times the distance. I would expect the difference to be even more dramatic.

My thought is that many have preferences and experimenting with both allows us to be comfortable with our choices. It's part of the enjoyment even if the logic isn't technically sound. I prefer my wildlife with a cropped sensor,but I prefer the full frame for landscape,etc. I'm sure that I could make better choices at times,so meanwhile I experiment and try to compare and see what I think looks better for me. I like trying to shoot and do a minimum of PP cropping. I do need new glasses,but I hope for the best!

In my particular case I use both, not that the quality images of one is better than the other.
DX is hard to beat for sports and wildlife. For portraits bokeh is better with FX.
Noise seems to be a thing of the past with modern cameras.

Reach is overrated. Difference in image quality is underrated.


Thank you thank you thank you! First off I agree with the hoggers that feel there is nothing wrong with revisiting old topics (there is nothing new under the sun). If you don't have the desire to, then just don't read or participate. Gene51 you are absolutely right. A pic is worth a 1000 words. We all appreciate you taking the time to post those pics, beautiful btw. I guess I have too much time on my hands cause I read this subject whenever it's posted, usually once a week :). My $.02 if expense or weight is a concern then go with the crop. Otherwise FF is the way to go. I once saw someone comment on this forum about this subject. He does drag racing and stated crop frame to full frame is the same as a small block to big block engines. According to him there is no substitution for cubic inches. And like Gene51 mentioned, compare oranges to oranges. If you compare a newer crop to a older full frame the differences may be smaller then if you compare sensors from the same generation. I have a Sony a77(crop frame) and a Sony a99 (full frame) with same generation sensors, both 24 megapix. If Pics taken with the a77 are stereo then pics from the a99 are surround sound. The full frame pics just have a presence that isn't there with the crop frame pics. I wont go into the better low light, high iso or depth of field thing.
