It seem wifi is often ruined by poor implementation and apps thats not always working.
Must be quite frustrating to work with.
As you might know i have been on board with the Joovuu x from day one, and we have seen a lot of going back and forth with that camera and its app.
So with one FW and APP version most things work good, then there is a now FW and suddenly som things that worked before dont work now, or work but not as good.
And this both go for functions in the camera/app, but even connecting wifi i found to be very flaky at times, and we had to go thru several firmwares and Apps before i was able to connect to the camera at will and not just by chance after trying xx times.
But for the most with the x cam apps i have found them to remain connected pretty good for hours on end, but i have also at times experienced the preview footage pixilate like something is running out of RAM or something.
The current x cam APP and FW seem to play ball well here, only major problem i have with it is that the preview in landscape make the app crash with the current app.
But no doubt i totally get the people / brands that want to stay away from WIFI in cameras, it do appear to add another layer of things to go wrong.
I view the wifi sort of the same as with the sensors them self, there is standards to how both work, so you would assume that if a SOC can understand 1 standard for sensors then all sensors that understand that standard should work, but thats just not the case it seem.
And i think it is sort of the same for wifi, you would assume there is regular protocols in play, and via those you ask the camera to do so and so on whatever language they speak.
But again it turn into a circus to me, its like one English speaking person want to tell another non english speaking person something, so the English guy yell out what he want to convey, and thats picked up by a multilingual Spanish guy that hear and understand the english so he translate that on the fly to german and yell it on to the next guy in Germany, and the German guy then call his friend in Denmark and tell him in Danish what the English guy yelled for the Dane to know.
And god only know how many translation errors have occurred under way.
Regarding lenses you would assume a company like Carl Zeiss would have information on such things, even stuff they would share for free with people.
