HPX250: Panasonic PX270 in Review

In fact the PX270 has the exact same DSP circuits (and all other image processing hardware) as found in the $30,000 PX5000. Its image processing circuitry is far advanced over what the older VariCams had.

[/COLOR]The chips and the lens are the only difference. And they make a difference.


Absolutely untrue. The PX270 is not using any "older technologies", it's using the absolute latest stuff.



If I have the PX270 for eval, I can say once and for all it's the exact same like 2/3" (except for the optics and sensor size). But I don't and still need to see it w/ my own eyes. For example, the most pressing is the preset WB accuracy on the PX270. The HPX250 5600K is pretty bad at it. Colors are never right most of the time on a sunny day. Now if the preset 5600K on the AJ-PX270 can stay pretty much consistence without annoying color shift just like the HPX3100 and PX5000, then I'm fully convinced that the PX270 is identical to the PX5000, at $20K cheaper. But don't have PX270 for hands-on eval just yet.

I personally installed the option proxy boards for the 2/3" cams and their circuit boards are fairly large. They have proper cooling fans. Even those the PX270 uses the same tech as the PX5000 something has to be scarified to crammed in all of those boards into the PX270's palm sized form factor. Just not 100% convinced that it'll be identical in performance every areas except the sensor & 3rd party optics. There're always things that have to be compromised. Unless this is a complete breakthrough cam in Panasonic's history that will obliterate all of their other products, my observations are: Big size generally yields better quality but too heavy and expensive. Smaller sizes yields easier handling, weight, and lower cost but compromises absolute quality. Audio preamps quality & performance on the PX270 are something I'm interested to know and if there are sacrifices on it. Hate having to lug around the Sound Devices 744T on every shoot. One can argue that the PX270 is just as good as separate audio recorder, but a dedicated pro audio recorder just sounds better in my subjective opinion. I mean it's crisp and accurate and has its own character. That's something I can never get out of any cam's XLR inputs.

The argument here is that the PX270 is an evolved camera design to the pro market. Film Rec (500%) gamma, 12-position color matrix adjustment were already on the 1st tape Varicam back in 2002-2003. But the new optional AVC Ultra 200, 1080p/60 CMOS sensors are also in for the 1st time on a 1/3" cam. So it's a mixture of old and current techs in 2014 repackaged in a smaller form factor and at an affordable price.

You mean 1/24 for 24p. Shutter off is always 1:1 with your framerate.
Not on Panasonic handhelds. Traditionally "shutter off" has meant "use the default shutter speed", which is 1/50 for 24p/30p and 1/60 for 60i/60p. It is silly; shutter off should mean "no shutter", so 1/24 in 24p etc. But that isn't how the AG-series handhelds worked. I don't recall which way the PX270 does it.
 
Regarding the PX270's circuitry, the product manager and the engineers both told me that it is using the same circuitry as the PX5000.

Yes, older cameras had big boards and fans and whatnot. But the PX5000 is their latest, most modern tech. And the PX270 uses the exact same circuitry. It isn't a repackaged HPX250.

Really? On my DVX and HVX shutter off would be 1/24. I work in 24p 99% of the the time and shutter off would brighten and get smeary compared to 1/48 or 1/60 which I usually used.
