comment Canon lenses with Sony A7r
@Bob Canon is waiting to recoup the investment in their current sensor fab or until they begin to lose a significant amount of sales before upgrading their 0.50 µm process to a 0.18 µm or smaller process that is required to be able to increase pixel counts without compromising on fill factor (and thus high ISO noise levels).

@BShaw the megapixel advantage is not huge, it's only 63% more, but the increase in dynamic range is much more significant: 428% (about 2.5 stops)

comment Canon lenses with Sony A7r
@Bob I did in fact just sell my 5DIII and managed to buy an A7R + Metabones adapter and still have money left over. It's a totally different shooting experience which is not for everyone, I'm using manual focus 99% of the time, and taking much fewer shots but at the same time not deleting any images that are out of focus or poorly composed. The resolution advantage is nice but not massive, unlike the increase in dynamic range. The reduction size weight is really nice too, but some will struggle with the ergonomics / controls if they have large hands or want to shoot wearing gloves.

comment Device to make continuous high-resolution photos?
@mattdm the question is relevant to timelapse photography now 4K is gaining traction...

comment Mirrorless Camera vs mid range DSLR — how to decide?
You're really asking two questions, what is the best (sensor) format: m43rds, APS-C or 35mm full frame, and what is the best form factor: DSLR or mirroless. It would be better to address them separately, specifically if you are thinking about the EM-1 it's worth understanding the tradeoffs of the m43 sensor, see: photo.stackexchange.com/questions/3986/…

comment Not quite straight lines; any help in Aperture?
Apple is discontinuing development of Aperture, so you'll have to switch eventually, it might be time to consider switching to Lightroom, which does have lens corrections built in.

comment Are Nikon DSLR sensors actually better than Canon's?
btw. the normalised "print" scores are 8 megapixels, not 5. That is however inconsequential, they could have chosen 12 or 16, the relative scores would be identical. This normalisation is actually less misleading, but if you want you can click the "screen" option to see un-normalised measurements. The key thing with DxO Mark is to ignore the "scores" and look at the actual measurements, there is a lot of data there to help you achieve the cleanest RAW file, which incidentally has nothing to do with shooting in low light or downsizing to 5 megapixels.

Not quite right, the reason Nikon cameras score higher is much lower read noise at base ISO (and better colour reproduction which skews the sport score). Low light noise is very similar between cameras.

The low light score is skewed by the minimum colour reproduction requirement, nothing to do with on chip NR. All you have to do with DxO mark is ignore the "scores" and look at the measurements, which tell a pretty accurate story when it comes to noise (though it does ignore PRNU). Comparing camera JPEGs is by far the least accurate way to compare sensors.

comment Slideshow software for handling 1000000+ photos
Can't you copy a small proportion of your images to another folder at random and then run the slideshow from there? That way the software wouldn't need to be able to handle so many images.
