I am thinking of upgrading my trusty D40 to a D7000. I use the D40 with old lenses -- some AI but most pre-AI -- so I focus and set the exposure manually. I have recently been shooting a lot of HDR, so I must also bracket manually (by adjusting the shutter speed), which is obviously a problem.
The features on my must-have list are: (1) compatibility with my lens collection (2) automatic bracketing* (3) a histogram capable of showing the individual RGB channels, rather than only luminence.
Does the D7000 have all these features?
*In particular, can I bracket with the camera in Manual mode? I assume I would set the shutter speed manually, then tell the camera how many exposures to take in each direction.
Autobracketing certainly. But only 3 shots. You can set for plus/minus 1 or 2 EV I believe, same as the D90.
The D90 has histogram for RGB channels so I assume D7000 must as well.
I believe for HDR you are supposed to set the aperture to keep that constant and then you just let the camera handle the autobracketing by setting the shutter speed. So you will want to shoot in aperture priority mode.
I believe you may be out of luck with the non-AI lenses but I am not 100% positive of that. The manual lists non-AI lenses in the ‘Incompatible Accessories and Non-CPU lenses’ list.
As to bracketing the D7000 allows a three-frame bracket sequence, and yes it will vary shutter speed in M mode.
And yes it has individual histograms for luminance and RGB. It is even better in that when on the histogram screen you can zoom in and the histogram is representative of what is displayed on screen. Also it even lets you check for blinkies (blown highlights) for the luminance channel as well as to check the individual RGB channels for blown highlights.
Hi Pete, Yes, that helps a lot, especially your information about the histogram.
I would be sad to hear that AI and non-AI lenses cannot be mounted on a D7000. They mount just fine on my D40. Of course there is no meter coupling with the D40, so I use an external light meter, and I expect to continue to do so with my next camera.
That is an odd feature of the D40 (and I believe other entry level DSLR’s) in that you can mount non-AI lenses without damaging the camera. Unfortunately if you mount them on the D7000 without the conversion modification you can damage the camera.
AI and AI-modified lenses on the other hand can be mounted and like the more pro cameras it can meter also.
Too bad. I'll look into having my non-AI lenses AI'd, assuming someone can still be found to do this (I know Nikon themselves no longer do). Any suggestions on where to get this done? Will the cost be reasonable, or will I end up spending more than the lenses themselves are worth?
