Adam Wilt has tested 3 – the Tiffen, Kenko and Formatt. Read his review at Pro Video Coalition:
https://provideocoalition.com/index.php/awilt/story/quick_look_variable_nd_filters/
In our quick tests, we haven’t seen any difference in picture quality between the various ones we’ve tested – Polaroid, Tiffen, Genus and Heliopan. But I don’t want to make an absolute statement without doing much more extensive testing. The differences are more in build quality and packaging. The Genus is the easiest to use, the Polaroid is the cheapest, the Tiffen comes with a really nice case, and the Helipoan is the most expensive, but German 🙂
Adam Wilt is a god, and whatever he says I’ll defer to.

“1080p is becoming passe”
I think that is a tad dramatic 🙂 Yes, there are cameras shooting 4K, but 4K is a long way from becoming the norm in the living room. 4K is more centered on film production. 1080p/i is going to be with us for a long time. NHK may be playing with 8k over broadcast in Japan, but that is not something most people are going to have to worry about for at least 5 years, and more likely 10, if at all.
If you are shooting for motion picture release, then 4K is the way to go. If you are shooting for TV, or the web, then 1080i is plenty fine. In Canada, where I live, the satellite and cable companies can’t deliver 1080p yet, so sending the much larger 4k stream down the pipe to the living room is not going to happen for a very, very long time. This is combined with the fact that too many people are watching standard def TV on their HiDef sets because they don’t want to pay extra for HD.
FYI – at CES this year, I sat through a demo of JVC’s 4K projector showing up-rezed 1080 footage to 4k on a 150″ screen. The 1080 footage looked spectacular.

“I want to buy Canon eos glass. So basically all I need to worry about is that I get an adapter with its own aperture ring if I’m using eos lens, correct? Is Novoflex a good adapter?”
Novoflex is a very good adapter – well-made, but pricey. No one who has bought a Novoflex adapter from us has every complained.
But – Novoflex doesn’t make a Canon EOS to M43 Adapter. A company called Birger is working on one, but it will be pricey.
For Panasonic M43 we recommend you get Nikon or Zeiss ZF.2 glass, and the Nikon-to-M43 adapter, if you don’t want to use native Panasonic lenses.
Nikon makes better lenses than Canon anyways 🙂

Lens to recommend – for the cropped sensor cameras, that’s tricky because they all have variable apertures except for a few, like the Tamron 17-50 f/2.8 and Canon 17-55 f/2.8 IS. Both are good lenses. But you’re not going to get any range and a fixed aperture unless you go up to the Canon 24-105 f/4 L IS lens (over $1000), which is the kit lens for a 5D.
As for firmware updates, I doubt it, since it hasn’t happened yet.

It’s a “bug.” Any lens (Canon, Sigma, Tamron, etc) with a variable aperture will produce this when zooming, even if you stop down to f/8.
The only solution is to either not zoom when in movie mode, or to buy lenses with a constant aperture (i.e f/2.8, f/4).
This happens on the 5D as well.

This exposure shift is a “bug”. It happens on both the 5D and 7D with any lens that has a variable aperture.
We tested it with lenses from Canon, Sigma and Tamron and happened with all of them. It happens in both Auto and Manual mode. It happens even if you stop the lens down to f/8 or f/11.
Canon says the camera is functioning properly as they designed it 🙂
The only solution is to use a fixed aperture lens, or not to zoom.

I want to thank David and Tim (and Shane) for the very kind words about my store that have been posted here – and to be honest, I’m humbled.
I’m not sure that these posts had anything to do with the phone call I got Monday afternoon – it seems now Panasonic Canada has given me the go-ahead to receive units around the end of March/early April.
Yes, Virginia, there is a Santa Claus 🙂
(Just one quick clarification on demo units – no dealer gets a free demo unit. We pay for them, and usually full wholesale price).

>Apple recommended to remove the card. And as soon as it was gone from the PCI-X slot. Aperture was stable as >all can be.
I can back-up the Aperture/Decklink HD issue. We had constant crashing of Aperture on our Dual 2.3 G5 with the BlackMagic Decklink HD card until we removed the Decklink. Aperture is now stable, like it is on our PowerBook (though running Aperture on a PowerBook is not the most ideal situation, FWIW).

>I’d go hard drives. They’re cheap enough these days to archive to- especially internal SATAs you can >dock with.
Hard drives are fine for short term storage, but are not a safe bet for long term archival storage. I asked Seagate Tech Support about what would happen if you stored a hard drive in a closet for 5 years, and then plugged it in to retreive data from it. They said it probably wouldn’t start up.
Hard Drives have moving parts in them, and like anything with moving parts, they require to be used so they don’t seize up. Your car won’t start if not turned on for 5 years either.
FWIW, I asked this of Seagate two weeks ago for this very reason – shooting with the Panasonic DVX200 and how to archive your original footage. Since we all know we’ll have to go back to our original footage sometime in the future …
