So does this mean infrared wavelengths are around the lower limit for taking images with a reasonable size camera? I've played around with the thermal IR camera

  The law for diffraction-limited systems is that the blurred spot size increases linearly with wavelength. (Double the wavelength, all else being equal, means twice as blurry.) Engineering concerns (for example, how big can you manufacture a CCD before it becomes prohibitively expensive?) determine what constitutes an "excessively large camera." Although, because infrared covers a 1000-fold range between visible and micro, I feel like it would be safe to say that cellphone-sized cameras might never be made for microwaves.
