I have posted comparative images showing the DOF control. What sort of comparative images do you need that can't be satisfied by looking at Imaging resource, DXO, dpreview, or any other place that shows side-side images between cameras? If you can't understand the math, and there's no sin in that, you can always refer to those sites.
You can also use your own aps-c cameras to see what the difference would be, you don't need a FF camera. Take a shot at 50mm f/2.8 and then one at 50mm f/4.5. Now, imagine a shot taken that combines that f/4.5 sharpness on the plane of focus with that f/2.8 DOF, and that would be the FF shot taken at 35mm f/4.5 from the same location. And if you wanted more than that "f/2.8 on aps-c" DOF, you could simply
stop down.
Or, take a shot at ISO 1600 in low-light, and then one taken at ISO 3200. On FF, the same ISO 3200 shot would have as much noise as the ISO 1600 shot you just took (or even less noise, if you were considering the D3s/D4.)
Quote: Do you even read what I write? This is so typical of you. When I point out the flaws in your methodology and commentary, you throw a tantrum...
In fact you have not pointed out any 'flaws in my methodology', and I'd say
your posts on this subject seem to be one long, extended tantrum.
You do realize that in discussing the benefits of FF and expressing a wish that Pentax play in this format, that isn't a value judgement on your choices and abilities, right?
Quote: You continue to be a propagandist for one format.
Really? Quote: But simple fact... most of the advantages you cite for FF are also advantages for 645, yet you continue to act like FF is the be all and end all.
No, it's just that the 645D is a very large, slow camera with less DR and worse noise performance than some smaller, less-expensive cameras, and which costs $10,000 for the body alone. The few new lenses available cost $1500 - $5000 each. It just doesn't seem like a viable alternative to FF Digital for general shooting. In a dedicated low-ISO landscape or advertising/studio portrait niche, it's a great choice - if you can swing $15,000 for a basic system.
Quote: I can quote you saying the pixel count in APS-c made them more prone to noise.
High pixel density + smaller sensor area (mostly smaller sensor area.)
Quote: .. You're arguments are all over the map... to the point that often I don't want to respond to them and let them slide...
My arguments have been consistent and on-target. But I wouldn't mind it at all if you elected to not respond if this is the level of response I could expect.
Quote: Here let me do the jsherman thing, take a great image that proves what I'm talking about..
It's an OK image, but I'm confused about what it's supposed to prove. I don't see any real demonstration of DR (a sillhouette is easy,) sharpness, resolution, etc, although some of that may be because its such a small reproduction. Is your point that you don't think you need low/mid-MP FF because you mainly shoot landscapes, and you fel aps-c is good enough for that? Haven't you already mentioned that, and has anyone tried to refute it?
Here, these shots were taken with my
iphone - does this then mean that there's no benefit for me, or for "99% of shooters" as you like to say, to any larger format than the iphone? :
