DMC-ZS30 with USB 2.0?!

I just viewed the specs for the Lumix DMC-ZS30. I loved them but I just don't understand why USB 2.0. Wouldn't it be nice to upgrade the USB speed to 3.0 with a bitrate of 5 Gbps instead of 480 Mbps!?

Yes but  USB3 is still pretty rare  and  this is in the context of  a consumer camera.

Hmmm... my computer is 3 years old and has USB 3.0 (certified). The standard is from 2008 and used in products since late 2009. I don't know how things are in the rest of the world but in Denmark almost every computer is now sold with USB 3.0.
You can actually not buy a decent 2012/13 NAS (Synology, QNAP, Netgear) or computer that doesn't have USB 3.0. So I don't agree at all.
We are actually talking about a 18.1 megapixel camera with support for Full HD (1920 x 1080) video. That makes transfer speed more than relevant.
It reminds me of the time I bought my first SLR camera. It was a Canon (Rebel) 300D. It had USB 1.1 though USB 2.0 had been there for years. That was the standard USB support for cameras back then and inexplicable when having to transfer large amount of images.
If you buy a camera like this you do it to make it last for years. That will be in a period of time where USB 3.0 will be even more relevant.
So why, WHY, WHY!? support and old data transfer standard when you buy a camera for the future?!?
Inexplicable!!!

Why?  Likely because it's still cheaper and easier.

Plus, they'd rather sell you a faster model later than to help their current models last longer.  With constant inprovements in sensors, speed, and features, most don't have a long-term view and expect the need to upgrade at some point.

Re: DMC-ZS30 with USB 2.0?!

What it boils down to is, "How do you want to use your development resources?"

It is quite likely that the USB port is integrated into the camera's processor. Developing a new processor and integration into the camera doesn't happen overnight.  If the current processor is adequate for the task, than development resources may be better used to create more features. A corporate decision made by product planning and marketing.

They don't have USB 3.0 either.

Hmmm... is this a guess or do you know for sure)
I don't buy it since the standard exist and it is just a matter of incorporating it. Well, that is how I see it.

Isn't there a simple and inexpensive solution here - assuming it is possible to buy a USB 3.0 card reader.

Yes, but then why then have USB 2.0 or 1.1 in the camera? Why workarounds? The answer is that many user like to use the cameras USB port to download their images. It is easier than having to open the camera taking the memory card out, finding the reader, inserting the memory card etc.

Is it to much to expect from a camera like this that it's transfer rates are decent? Not just for now... but for the time and years to come. The years where the camera will be used to take 18.1 megapixel pictures and Full HD (1920 x 1080) video. A use where 5000 Mbps will be noticeable better than 480 Mbps?
I am not asking Panasonic to invent something new. I just would expect them to adopt a standard that is more than 4 years old.
Best regards,

I'm surprised no one's said this, so much so that I felt compelled to create an account to do so... Why no USB 3.0? Simple, same reason you aren't seeing it on smartphones yet, the vast majority of flash media used in either device isn't fast enough to saturate USB 2.0, let alone 3.0...

Most smartphones or SD can't be read from much faster than like 30MB/s, so why would they bother with the added expense of a faster controller when 99% of people won't reap the benefit?

Also, believe it or not USB 3.0 controllers are still more expensive than USB 2.0 ones. Intel didn't even integrate it into their desktop chipsets until the very last generation (until then it required an extra chip on motherboards).

What is new is that you charge the battery (and power the camera while viewing) through the usb port. You can attach the camera to your computer to charge the battery (and power viewing) or use an AC adaptor with a regular usb slot (supplied).

Welcome aboard!

This sounds reasonable to me.

And, I really haven't found download time to be a problem, although I am somewhat atypical in that I don't fill a card very often, nor have I ever emptied a battery in less than a day, in my ZS19 even on my trip to Japan last year.
