[QUOTE="BackdoorArts, post: 447119, member: 9240"] It's a fact of the format. Your "DoF bar" is called knowing your aperture, particularly given the presence of the DoF preview button. As was said, there's always Live View if you want to get anal about precisely what is and isn't in focus (and many people are and do just that). Yes, the camera knows what lens is mounted (assuming it's the proper type). Are you suggesting that Nikon install a DoF calculator that will display the total DoF (in inches? feet? cm? m?) based on the current focal length, calculated distance to the subject (which requires you engage AF) and aperture? There's an app for that, you know. I suspect the subset of photographers who [B][I]need[/I][/B] that function because the available tools (i.e. that button on the front and Live View) aren't sufficient are likely so small that to clutter the firmware with something like that to be engaged on every depression of the shutter is impractical, particularly since it would need to replace something more needful in the viewfinder. Now, perhaps in a mirrorless with a digital viewfinder where information can be displayed [I]anywhere[/I] this could be an option. One other issue with a preview is that it requires the physical closing of the aperture, and at some point that's going to interfere with the AF function as well (though the mechanics could be coordinated to AF [I]then [/I]close, but what does one do in AF-C mode?!). I file this in the "people in hell want ice water" category. [/QUOTE]
