I guess you mean brand hopping pako, I have certainly been guilty of that ever since my first DSLR a Olympus E-510, which I kept for nostalgia.
classiccameras, no brand hopping here. I went from Minolta to Sony when the A700 with 16-80 Zeiss zoom came out and stayed except for Panasonic LX2/3 & 5 until Sony came out with their RX100 series. Had great faith in Sony's ability and consider myself vindicated.
As I stated earlier I am now at the point where I cannot see me spending money moving from my RX100M3/A6000 position. They are more than good enough for what I need to do and are light in the bag as well. The same applies to my lenses. Great.
Not sure when other users reach the same point and simply replace when current equipment breaks down for good. I see the Sony A7 iterations as attempts to entice professionals and enthusiasts who have the money to continue the upgrade process due to insatiable pixel peeping desire. The other segment is surely the pro's who desire lighter but capable equipment for out of studio work (well paid). I think that the A7r series and now the Hasselblad X1D mirrorless fall into this category. Reference Pako's
no printing system really goes beyond 300 or 400 dpi
, I have no less than two Epson P50 colour printers of some vintage. Using Jet Tec inks I can get A4 that is sharp enough for my purposes. The prints are really very good. Cannot do proper B/W printing as lacks the extra grey cartridge, but then I don't need B/W. Can't see why I should update.
