Noob question re: Canon vs Nikon lenses

Hey,

I wanted to ask something probably simple, but unknown to me, if I may!

AFAIK modern canon lenses do not have a manual aperture ring on them, whereas modern Nikon lenses do.

I currently have a D90 and am (99%) going to get a 7D soon (post my current weak food poisoned state!) but am curious about lenses.

I have three Nikon lenses, a 50mm f1.4 (modern) and a 105mm f2.8 (older, manual) and a Tokina run around tele. When using the 50mm I need to set the aperture to f16 on the lens and select the aperture on the LCD, as one does, before it will shoot (to avoided the annoying FEE rubbish).

When using the 105mm manual I can happily set the lens at whatever I want and it will be fine, hurrah!

With the D90 the manual lens is much more convenient because I can easily stop DOWN. I.E. if I set it to, say, f5.6 and then enter the Live View, I can then just stop down to f8 and it will be naturally darker, which is lovely.

However, when using the 50mm, this won't happen because I set the aperture electronically before entering live view. I can OPEN the iris more to f1.4, but I can't stop down to any number greater than that which I had selected when I entered live view. I.E. if I had it set to f5.6 when entering live view, I cannot stop down to f8 after entering live view, I have to exit live view, set electronically to f8, then re-enter live view.

This is a PITA, but part of the problem with the D90 and it's lack of manual controls and the endless tricks we do to get a well exposed, low noise, good shutter speed, movie. Manual lenses for the D90 therefore are king b/c of their flexibility.

I know the 7D is different in that you have full manual control over shutter, iso, aperture etc. However, I was wondering if this means Canon lenses are fine for video usage or if we should still covet Nikon manual lenses for their flexibility?

I want to use lenses with Image Stabilisation built in b/c I shoot a lot of handheld (I'm even going to test drive a RedRock Captain Stubling soon to see if that is good for my handheld endeavors) and the extra help is much appreciated. This suggests Canon lenses to me to take advantage of this (and/or Nikon lenses w/IS built in).

However, I'm concerned that the lack of aperture ring reduces one's control and therefore if I'm going to have to stick to Nikon lenses w/the adapters that are floating about on eBay.

Can someone please clear this up for me - am I going to have to continue to use Nikon lenses or are the manual controls on the 7D comprehensive enough that I can easily use Canon lenses and still have the control I need.

For example, if one can manually control the aperture on the 7D, but it's through the menu, can you do this in 'real time' in live view, or do you have to do what you have to with the D90 and select an aperture, enter live view, check it, exit live view, select another until you get the right settings?

I know this is less of a hassle than w/the D90 because you are controlling the variables (iso/shutter etc) so it'd be mostly about getting the right exposure, but it still seems a bit of a silly way to do things so hopefully I'm wrong and there's a better way!

Are people still using their Nikon's b/c they've invested heavily in Nikon glass vs any real technical considerations? My investment isn't great so I'm prepared to sell my Nikon glass if I get the benefit from the Canons.

Cheers!

You can control aperture in real time via the wheel while in live view and recording.

The 7D crushes the D90 in usability so hard.

You can also adapt your Nikons to the 7D body, no problem. Using them for image reasons, or money reasons, but not usability reasons.

Although most of the older Nikon manuals have much nicer manual focusing than new Canon EF lenses.
