Marco Arment knows fuck-all about
(a) quality (b) photography (c) camera hardware (d) captioning photos
There isn't a sentence in that blog post that isn't either wrong or half-true.
Use the camera however you want. When you start finding that your tools can't keep up with your imagination, improve them. Photography is about light, and capturing it, first and foremost. See the light, see it change, make it change, appreciate it, capture it, and stop reading trash from insecure baldhead attention whores who take godawful photos like this: http://www.flickr.com/photos/marcoarment/5196670116/in/photo...
Sure, some people think sharp lines, high contrast and Schneider-Kreuznach-like resolution == high quality. And it does, in context. If you want sharpness, high contrast and resolution. You may also want to play an Ibanez RG1570 in the same context. But to others, artistic quality is a more useful way to describe things - and it can cheerfully describe all types of optics in that useful way, a way that doesn't need to stick things on a scale of good to bad. Marco appears to have been in the wrong place at the wrong time and caught me on full-flame-on mode - but he's also being narrow-minded and only looking to one context, which doesn't help anybody make better pictures, it just helps them make sharper and bigger pictures.
