Originally posted by Chris Mak I wholeheartedly disagree, I own three Loxia lenses that will no doubt produce stunning images on the A7r4 (they already do on the A7RII and have no problem resolving that sensor to the max.), and I have a Canon 400DOII that will also benefit a lot from the 61mp sensor. The A7r4 has a one-button touch switch between FF and APS-C mode. Add to that the 5,76 EVF which will no doubt be stunning esp. in APS-C mode, the AF with full coverage of the APS-C field, and all the latest of Sony's AF wizardry, and I feel this may well be a single camera that makes all other cameras redundant. I found the money I spent on the Pentax KP well wasted for instance.
There is nothing in those sentences that consider anything practical of taking pictures. Everything written here is about specifications, and there is nothing in your comment about photography. You mention about how good is the 5.76M EVF, how good is that in practice? How good is 5.76M EVF compared to optical, in practice? Now about Canon, for example, Canon have mostly never cared about their sensor dynamic range, because when you print, or display images on a 4K monitor, the dynamic range is limited to 10ev at most. On the other hand, Canon have cared a lot about the choice of lenses, stability of lenses over temperatures in winter and summer , weather sealing (that's practical). But now, customers care about mega pixels when they never print, they can about dynamic range that they never use and they care about AF full coverage of the sensor area when focusing in the corner will never yield a good photograph because good image are focused around 1/3rd of the frame, most of the time. Canon also offer after sales services better than anyone else, something Sony doesn't offer. Overall, Canon made cameras for being great tool practically, but now cameras buyer mostly readers on online reviews are attracted by Sony, who make camera for looking good on internet abstract vacuum, so in fact you are part of the target market of Sony who care about spec sheets and never confront how the specs translate in real use. Sony are looking after market share, they are doing things to offer camera systems that serve photography well. The motive of the Sony buyer isn't photography, the Sony buyer likes to own high tech. Yeah, that cool to have 500 AF points that cover the whole image frame, but I'd like to know which of those AF point are locked for successful images, most the 1/3th area around the center of the frame, exactly like it is for DSLRs.
