No.
So far we have lower resolution.
Even the A7r with 36 MP has a lower resolution than the K3.
Canon 5DS.

I own a car but since I'm legally blind I can't drive it. I use trains all the time, buses once in a while.

Funny nobody mentioned the exaggerated wide angle distortion on APS-C yet. The single most important reason for me to go FF was the very noticably less distortion when shooting (U)WA lenses. But maybe that pro goes into the overall higher image quality category?

Pro:

- shallower depth of field
In most cases, shallow DOF is a con not a pro.....

Pros

- Psychologically you'll be relax that you have finally upgraded to FF and probably never look back to APS-C anymore.
- Higher ISO performance.
- Better wide angle performance.

Cons

- Expensive
- Probably incompatible with your current gear
- Shorter shutter life span?

So, in a nutshell, or in as an exact manner as possible, what are the true pros (and cons?) of using a DSLR with a Full Frame sensor?
Some PROS:

For similar sensor gen, you can realize less noise for the same FOV and exposure, and better DR as you shoot in situations hat move you up from base ISO.

You'll probably see anywhere from .75 to 1.5 stops better performance there ^.

You'll also have a bigger viewfinder, and probably see more accurate AF, although that's so dependent on the manufacturer's AF implementation that it's hard to attribute to "FF".

You will generally have more ability to control DOF outside of stopped-down landscape shooting.

Your lenses will show different FOV. 1.5x wider. This is a pro to some, a con to others.

Some CONS:

Larger body, sometimes larger lenses, probably more expensive (although it doesn't need to be depending on lenses.)

And, can too many pixels be packed even into a Full Frame sensor, marring its performance?

.
Yes Don't worry though, we're not there yet with Sony Exmor 36MP - that's one of the best sensors you can get in terms of SNR and DR. We'll have to see how that 54MP sensor stacks up when it arrives.

Pros:
- No more endless number of "When will Pentax make FF body" threads

Cons:
- We are going to miss the discussion in the "When will Pentax make FF body" threads

using the lenses for what they have been designed for
They were designed to take pictures. You can do that with an APS-C. That's not a "pro", even though it's heard often.

QuoteOriginally posted by max_pyne Quote
no more multiplying with the crop factor
You don't have to do that either. Look in the viewfinder and frame accordingly.

That "pro" might make sense for someone with a lot of history with 35mm, but it's a subjective thing.

QuoteOriginally posted by max_pyne Quote
- higher resolution
- even better high ISO
Those two are often mutually exclusive. You'll get better high ISO performances if each pixel is larger. When you increase the resolution, pixels get comparatively smaller. So it's true to some extend, but if you gain a lot with one item, you won't with the other.

QuoteOriginally posted by max_pyne Quote
- shallower depth of field
That's not true. At all. DOF is not linked to the sensor size. It is marginally linked to pixel pitch, but the main contributors are focal length and distance to subject.

There is a lot of misconceptions linked to the fact that people confuse field of view and focal length. Let's not do that here, please.

Dream on. There will be endless complains about when Pentax is going to release another FF body. Why is is so cheap. Why it is so expensive. Why it isn't 24mp or 50mp or whatever etc....

In general, as sensor size increases you get better wide angle results and better ISO performance. You sacrifice reach for small telephoto subjects.

What photographs tend to benefit from FF? Wide angle. Landscape. Low light. Portrait styles that need thin depth of field.

Some photos might be better with APS-C. Extreme telephoto. Birding. Action shots that need very fast burst performances.

Yes, it is possible to have too many pixels, but it depends on the type of photography. As you increase pixel count (and pixel density) you get more resolution while processing time and memory usage suffer. If you have enough pixels to crop and print the largest photo you ever need, extra pixels are "wasted".

maybe silly, but one of the advantages that came to my mind with a FF with crop mode is, when having two prime lenses, actually means four focals..
You're correct that it's silly. Crop mode is just another name for digital zoom. Activating crop mode on a FF camera wouldn't change focal length. It would just give you a lower resolution image missing the outer edge of your non-cropped image.

Does full frame make any difference if the photographer doesn't make prints?
What number of Forum users still make prints? It would be interesting to know.

That's another story. We can also speculate when Pentax will release the first 645 FF

Wide angle distortion from APS-C format can be very easily seen without printing.

Voigtländer just presented a new 15mm that covers FF, btw!
