Video: Lens recommendations?

Our big boss is apparently potentially interested in investing time and money into the video side of things. Ok, fair enough.

Thing is, the 7D overheated today and I don't particularly like it. I can't get on with the AF and the zoom creep on the 15-85 as soon as it's pointed down and I don't like the crappy minimum aperture on the lens.

So, I'm looking for some recommendations for lenses to put on a K5 for video. Right now, I'm seriously thinking either 14 or 12-24mm and maybe a 35 limited. A 70 would then make up the "long end", I have an 85/2 and 50/2.8. However, that's still a grand's worth of lenses and another grand for the body. It's cheaper than a 7D, which is the nice bit

For my own use, I think I'll try and get a 28/3.5 as discussed elsewhere. Of course, I then get access to the lenses if I want / need them

Has anyone done tethered video shooting with a K-5? Is it even possible?

I'm also going to have to consider a rig. The Zacuto finder looks to be pretty much essential as I *have* to use Live view to assess focus - at least on the 7d - which I don't really want. I also can't really see it well enough and the f4/f2.8 of any of the above lenses is enough to ensure minimal DoF at short working distances.

Any other thoughts on Video on the K5 more than welcome!

Have mostly stuck with DA* zooms when shooting video on the K-7, mainly for versatility.

One thing I did find when shooting speeches at a wedding recently was that the sensor will heat up as well like you had with the 7D. With 2x K-7s we had to keep swapping over to the other camera every 8-10 minutes or so. Hoping the new sensor on the K-5 is better at this as it should have been designed with 1080P video in mind from the start.

Hope someone with a K-5 can let us know about this!

hmph, that's not good. Though the 7D did only really heat up after it had created 1.2GB of files in one go and it was pretty warm in the flat. Was very convenient to have a balcony at -1 outside

I can request a pair of anything, as it also makes life easier with regard to the "making of" films and as backups. I think this is one of the reasons I need to rent something before I can make a good decision.

I mainly use my Sigma 24mm f2.8 'Superwide' - don't need AF for video, and the large-ish aperture gives the shots a nice look. For video, the faster the better I'd say. So the DA14 would appeal, as would the DA35... but why not the new DA-L 35?

What's your thinking behind the 28/3.5?

Two points of interest:

A dslr is a fine addition to a video kit, but cannot replace a proper video camera.
The heat issue, recording times and sound issues are the main reasons.

If you add a dslr to a video kit, look for lenses that offer capabilities beyond the video cams capabilities.
Ultra wides, fisheye, fast aperture primes.... super telephotos.

and shoot manual...

The teams within the building already ignore video cameras for the most part; they shoot with 7Ds or 5Ds. Sound we're not interested in at all, as there's effects and a voice-over to be dubbed afterwards.

A 35/2.x is what I'm thinking of, and the 14/2.8. A 10-17 could offer us something very interesting indeed... but I don't know if it's really up there with the image that the company wants to project (and this is company business).

Manual was already the order of the day on the first shoot. I was also mainly using around 1/30 to 1/80, depending on the subject, and ISO 320 or so. But I was limited to f4 by the lens and I'd like to be able to drop DoF right down when I have a loupe to help locate focus correctly.

Our video specialist was taken by surprise when it turned out that there were no video cams in use by one in-house team and when they realised about the flexibility and lens options, they were sold on the dSLR idea. It also helps that I get most of the quality of a real video camera at around a tenth of the price...and one of those has been making movies for years using video cams and now? 7D.
