Like in the topic. Is it possible to change iso when during recording. It was impossible in gh2.

Why would you do this?

Simple... you are filming live action that goes from light to dark and want to be able to raise/lower the ISO without having to STOP recording and possibly missing something while waiting for file to write, then change ISO, then start recording again. You might miss something in that time.

+1. That'd be like saying, why would you need to change aperture while recording. More flex. Plus, I am starting to really dislike variable ND filters. Having to bring multiple lens hoods to shoots, the image quality hit, the flaring issues, etc. Often times, bright light behind the subject causes light to bounce around inside the filter. No hood can prevent this. Having to bring a hood for filter-on, and another hood for filter-off is super annoying. I really am considering high quality, standard ND filter sets. Don't have any experience with them really, but am hoping for better image quality results and less bulk in my bag. If I slap on a 6-stop ND filter, being able to boost the ISO while recording is major.
 
Don't think you can do that one. I vaguely remember checking but don't have my camera in front of me.

I know. My point was that it's likely very close to the attitude lens makers actually have. You and I know it's a ridiculous viewpoint, but DSLR equipment makers seem not to get it. If they did, then every lens made since the 5D MKII appeared would have non-clicked iris rings on the lens, with a built-in motor for auto iris.

Would you be willing to pay more for these features? To find these in a solid zoom you are looking at over $2K and then people will just complain they are too expensive. The DSLR video crowd is a very small drop in these lens manufacturers buckets. Not worth all the expense and R&D to rework their current lens lineups. Some manufacturers like Rokinon are coming out with affordable 'cine' lenses which are great bangs for the buck but all manual.

How about changing white balance during recording?

Sure you can: auto white balance. It changes the white balance according to the lighting conditions, but unfortunately you have no control over how it works and it often doesn't assess the lighting color temperatures correctly.

That's pure nonsense. There are plenty of affordable lenses out there that have iris rings. It can't cost any more to have them smooth operating instead of hard stops. And there are also affordable lenses out there with servo zoom, so motorizing the iris isn't going to increase the cost by a factor of 3 either.

I'm not sure you understand how complicated lens manufacturing is.
All of the zoom lenses with aperture rings are old. Please name some modern zoom glass with physical aperture rings?
Each lens maker would have to re-work their current lens offerings to include physical aperture control which costs them money for a tiny segment of the buying market. You can get your old manual aperture lenses 'de-clicked' but it isn't as cheap a process as you probably want.

Sure there are affordable servo type lenses but none of them are fast or amazing optically. Sacrifices have to be made.

If you want a fast zoom lens you are going to pay $$ and that is even without your dream features. That is the reality of lens making.

You're only proving my point about the attitude of lens makers here.

Proving that lens makers are in a business? If they have to re-work optical fomulas it will cost money and that will be passed on to the customer in a higher price. Weren't you complaining that the 12-35 Pansonic X lens was too expensive? Adding a manual aperture (more R&D and manufacturing cost) and servo function (again not even possible in a lens that fast and zoom range) will double the lens price at least if its even possible.

You can complain about lens makers but starting with unrealistic expectations is setting yourself up to be forever disappointed.
