With the Sigma SD Quattro who needs MF? - Sigma SD Quattro H

With the Sigma SD Quattro who needs MF? - Sigma SD Quattro H
'So it's obvious that Sigma are going for a market that craves sharpness and detail resolution over all else and isn't that bothered about high(er) ISO performance. Aimed straight at me of course. And I have to say that since I can upsize my current camera files to 50MP with astonishing results, what can I get from the H?'

Sigma SD Quattro - A 'walk on the wild side?'

Sigma SD Quattro - A 'walk on the wild side?'
'In a photographic market that is showing a steep decline in the sales of 'proper' cameras I just wonder how many review sites, photographic bloggers and other assorted self appointed 'internet gurus' realise that part of the blame for this lack of enthusiasm to buy gear that enables serious and creative photographic expression is down to them'

Sigma SD Quattro and 21:9 Panoramas - Fast stock photography turnaround
'It doesn't happen too often, because I normally take a long while to get round to editing and uploading images, but occasionally I take a picture, caption, keyword and upload it to a stock library and achieve my first sale the same day.

The Sigma SD Quattro - The Foveon sensor gets a camera to do it justice.

STOCK DIARIES - Does the Sigma Foveon Sensor work for Stock Photography?
'The Foveon sensor with it's high-resolution ultra-sharp images would seem to be a likely candidate for shooting low ISO stock landscape / location / nature / travel material. And while that is certainly true, there are a few issues that make it less than ideal to use.'

Leica Q (Typ 116) compared to Sigma DP2 Quattro - Am I really bidding on a Leica M8?

Leica Q (Typ 116) compared to Sigma DP2 Quattro - Am I really bidding on a Leica M8?
'Add in the fact that the Leica is MUCH better at high(er) ISO's and a faster camera as well and it's clear to me which is the most useful camera. However, the fact that the Leica costs 4x as much hasn't escaped me.'

Super High Resolution Mirrorless - Olympus OM-D E-M5 II - Sigma DP2 Quattro

Super High Resolution Mirrorless - Olympus OM-D E-M5 II - Sigma DP2 Quattro
'Both the Olympus OM-D E-M5 II and the Sigma DP2 Quattro have pretensions to offer super high resolution images. The Olympus, via it's High-Res mode offers a 40MP jpg. and a 64MP raw file. This however requires no subject movement, an exposure that requires sensor shift and therefore a tripod. The Sigma offers a S-HI jpg. option which is 39MP and an incredible 'Double Size' option from raw which is an unbelievable 78MP. So do these options produce what these numbers indicate, very high resolution images. And if so, are they actually any good?'

Speeded up Sigma Photo Pro

Speeded up Sigma Photo Pro
'After getting my Sigma DP2 Quattro, I tried out the Sigma raw software - Sigma Photo Pro - and quickly came to two conclusions. Firstly it worked with almost mind numbing slowness, with adjustments and saving taking several minutes to complete and secondly I didn't see much benefit over the in-camera double size jpg. files I was creating. However, with the acquisition of my new PC tower with i7 turbo boosted quad cores and 16MB of Ram, I thought I'd try it again. And Sigma have seriously updated it.
