realkrs,

Houston has some good optical shops nearby for obvious reasons. Now if they started to do refinishing for the brand C lenses, you would see a huge improvement in their optical quality.

120k through the shutter is quite a bit. Just got one from a buddy and it has 15k. Virtually mint. Good stuff.

Bit,

Correct. The better optic is about HALF the cost of the brand C 800mm. But then you're adding AF, aperture control, etc on the brand C.

Focal length will always the same for a lens, whether it be 35mm, APS-C, APS-H, 4x5, etc, it's the apparent field of view that changes with the different sensors. The other factor is the light cone...

Be careful when handling the 50 1.4 Canon lens. The focus barrel has a very thin spot internally for one of the focus cams. All it takes is a light knock and it'll be rendered useless since the...

Bit,

Even with the gain turned all the way down to the second to the last notch, you'll still get lots of noise. Canon DSLR preamps aren't up to the task. What are you recording?

Bit,

Canon makes some of the worst preamps for DSLR movie usage. I'd suggest getting an external recorder. Just stay away from the cheapo Zoom H4 series. The Sony PCM D50 can be had for a good...

The 1D II and 1D II N had much better focusing systems than the 1D Mark III or the 1D Mark IV cameras. 1Dx is the only one better in some cases than the older Mark II / II N as far as SOLID...

Speakers first! If you're after sound quality, I'd get some Dynaudio speakers. You'll have to find out what sizes your IS has and then go from there. Definitely some custom work but you'll beat...

A baffle board and a ring spacer will do nicely. As for the material behind the speaker, use Deflex. Madisound used to have them, but it's been over a decade since I've purchased any. Great stuff....

Interesting.

This would also explain clarkvision.com test of why the 1d Mark III had a sensor range of 15 f/stops. But, since Canon uses 14 bit converters and pads down the info from the sensor,...

Glad that the megapixel race has died down somewhat. As for the dynamic range race, it'll be fun to see who makes the 20 f/stop mark. Canon is still at 12 f/stop. Phase/Hass currently at 14 with...

Bit,

Converter bit depth is not the same as sensor bit depth. Usually the converter has a couple of bits for overhead in sampling.

Chikoo,

Correct. 12 stops of dynamic range is typical for the Canon EOS cameras. As for the larger medium format sensors, they are now at 14 stops of dynamic range.

For speed and accuracy in autofocus, the 1Dx is unmatched. Have to remember that they dedicated an entire Digic 4 processor just for AF functions alone. The older 1D4 is a bit spotty on focusing. ...
