Thanks for the all the answers!
Well, as for the DOF goes - I agree. Whenever I can, I just move as far as I can from the subject and zoon in - so I have a shalow DOF.
But what sound do you get from the DSLR's? Is is good enough for professional interviews?
And regrading the LCD screen, your reply means that I need to have a calibrated monitor around at all times?

There are numerous problems with this. First, if you zoom in, you are no longer at F1.9 wide open. You are at F2.8 or thereabouts. Second, zooming in, also makes any camera shake more visible. TERRIBLE if you are outdoors. Also terrible if you are on a wooden floor and anyone else is around. Third, it means you need to have an excellent tripod, because an inexpensive one will transmit every vibration right to the lens.

No. But I record separate sound on the EX1 anyway, so that's no big deal to me.

Why? What will a calibrated monitor tell you that the scopes won't? What are you trying to do? All you need to know in the field is that you are neither overexposing, or underexposing, and that the colors are reasonably accurate. Anything else can be handled later unless you are going live to broadcast. If you are going live to broadcast, then having a calibrated monitor on-set should be standard procedure.

I was poking around the net this morning and found a germane article by our friend Adam Wilt on many of the topics being discussed here. I will save editorializing for now. The link is below:

I know why you're saying that, but in reality it's a different situation. You may have achieved a defocused background, but have also totally changed the perspective. Relative to somebody sitting at their desk, you are now not seeing anyone at desk - just maybe someone with a few books in a bookcase behind.

Normally when differing dofs are talked about, it's assuming the same lens angle of view. So the amount you see in the background doesn't change - just gets more or less defocussed.

"Secondly, the lens seems to be pretty sharp around F5.6-F8. Not too bad at F4 or F11. Outside of that, well..."

I'm quite surprised to see Perrone say that. My experience and many others is that the EX-1 and EX-3 lenses suffer from serious diffraction issues at f stops more closed than f 6.8. I try to never shoot at f8 or beyond because it gets progressively softer.

That said I find it perfectly acceptable wide open in most cases And I shoot that way often. It is probably best around f4- 5.6 but I've never tested.

Re exposure : I didn't read this entire thread so maybe this is irrelevant, but if you are trying to set exposure using a meter on a video camera you are wasting your time. its not linear. Learn to use your zebras or better yet get a monitor with a waveform. The histogram can be useful, but the best thing is to use zebras and a waveform.

Thanks for your help Perrone.

I haven't been thrilled with the camera wide open, but you guys are probaby right on the iris being more stopped down. I seemed to remember it was best "in the middle" and was wrong on the range. Been a while since I really stopped down.

Hi Perrone,

A couple of questions.

Where can you get a $14 adapter that allows one to use Nikon lens on Canon? The ones sold locally I have been told are around $200 dollars. All of my Nikon lens except one are the older prime variety with physical aperture rings. I have one very nice 17-35 AF-S Nikkor 2.8f which I would want to be one of my main operating lenses. Will the cheaper adapter you use work with this?

Second, question. Are there any practical limitations that your camera, the Canon T2i has over the D7 and the 5DmkII beyond size of the sensor and completely obvious stuff like that.

This is what I use

Nikon Lens to Canon EOS Camera Adapter Mount NEW - eBay (item 300453982574 end time Sep-07-10 08:52:28 PDT)

Yes. Should work just fine. All my Nikon AF and MF glass works just fine.


I think you mean the 7D. The T2i does not have the 1/3 stop ISO ranges which seem to be more noise free in the blacks (as compared to the 7D). The T2i only has 480p video out when an external monitor is attached. The T2i takes SDHC cards and not the more robust Compact Flash cards the other two cameras take. The build quality is not as good. That's about it in terms of video. Stills is another matter entirely.

I am VERY pleased with the T2i and I take it on every shoot now.

Hi Perrone,

Yes I did mean the 7D. You bought adapters for all your lenses or just a couple?

Thanks for all the info.

I bought ONE adapter as a test because I was skeptical. I am no longer a skeptic.. :) I'll be buying one per lens very soon. Right now, I have to swap the adapter lens to lens. Only takes a couple seconds though.
