I've been obsessing over the Foveon sensor since the SD-1 was announced. I thought no way was I ready to start investing in a whole new system. I'll just stick with my canon setup, 5D Mark2, 24-70 f/2.8L, 17-40 f/4L, 70-200 f/2.8L IS II, 580ex2, and the new 600RT with a couple of pocket wizards. However, doing several weddings and portraits, I've come to realize that every time I take my 5D Mark 2 out, it's just such a hassle, and I feel like I'm working rather than having fun. So I invested in a Fuji X100. I started taking that with me to concerts, and the low light ability blew me away... it looked as good as my MK2, with better Auto Focus! (Sorry my MK2 is ~ 50% at best -- hoping to make the move to a mk3 soon) Image quality on the Fuji X100 was also amazing, the Astia shots were amazing for portraits, and my velvia shots were stellar. This was truly a photographer's compact camera. Then sigma announced the DP-2M and the DP-1M. Compact version of the SD1, but carries the exact same sensor (15MP APS-C). I thought about it, and decided to sell my X100 in favor of the DP-1M/DP-2M. Didn't know which one, and I realized that since I'm not really gonna be taking a lot of portraits with that camera, I'm gunning for the DP-1M. I realize that this was going to be a huge sacrifice: no flash, horrible write speeds - even on the fastest card, awful low light ability, laughable video, and probably the worst battery life to ever graze a digital camera (compact at that!) and no Photoshop/Lightroom support -- meaning Sigma Photo Pro for raw files only. Plus I would have to spend money to obtain one! But still I had to have it. Sold my Fuji X100, and got the sigma. took it zion with my 5D Mark 2, slapped on a 24-70 f/2.8L, and decided to take some shots, to compare. Though this comparison is a bit flawed (i'll make more adequate comparisons) I was completely shocked. Obviously photogs know that Full-Frame doesn't give a camera it's "image quality" but the ability to view more in frame (compared to a crop sensor). But anyways, this was going to see what kind of kool-aid every sigma user's been drinking... This is the original image from my 5D Mark 2 with the 24-70 f/2.8L I used photoshop lightroom to fix exposure, and to color correct (balance). Did not do anything with CA. This is the original image from my Sigma DP-1M. I imported the image into SPP and it came out like this, pre-balanced. I thought, awesome. I'm just going to export it. Though they are 2 completely different images, albeit different focal lengths, the same aperture, the same iso, I figure this was flawed from the beginning. Sure the color of the sigma looked more natural, but that wasn't what blew me away. This is the 100% crop of the 5D Mark 2 of the sharpest, most in focused point of that frame. This is the 100% crop of the Sigma DP-1M of the sharpest, most in focused point of that frame. Wow I was blown away. Though they are 2 completely different pictures, and the test was flawed from the beginning, the Canon can only get marginally better. It will not be Sigma DP-1M good. Now I'm drinking Sigma's Kool-Aid also!!!
