Sigma SD14 is a fabulous camera, capable of producing exceptional, vivid and professional quality photos that can impress your friends, but it has several shortcomings.
I have used this camera for three months and took over 4000 pictures with these four Sigma lenses: 30mm f1.4, 50mm f2.8, 18-200mm OS and 70-300mm APO. I also have the Canon Rebel XT and Nikon D40 systems.
SD14 works great when there is a lot of light, like shooting pictures during daytime outdoor or inside a well-lit studio. Without sufficient lighting, pictures can be dark and grainy. On the other hand, Nikon D40 produces better indoor pictures.
If you are upgrading from a point and shoot camera and have less than a thousand dollars to spend, I suggest you get the Nikon D40 with its kit lens and the AF-S 55-200mm VR lens. Number of megapixels does not matter, but the sensor size does. D40 has the same sensor size as D300!
If you don’t look at price tags when you shop, then the Canon 1Ds is for you. It’ll cost you ten grands when you include a couple of L lenses and flash speedlights.
SD14 is not an all purpose camera. It is suitable as a 2nd camera to an entry level or prosumer DSLR cameras. It let you take artistic and lively pictures to wow your friends without breaking the bank.
Pros:
1. Wow quality photos. Picture colors are absolutely amazing.
2. Camera relatively cheap.
3. Sigma professional lenses much cheaper than the Canon and Nikon counterparts.
4. Great for taking still subjects such as portraits, flowers, architectures and landscape.
Cons:
1. Slower auto focus when compared to the Canon and Nikon systems.
2. Metering less accurate when compared to the Canon and Nikon systems.
3. Battery life relatively short (150/250/400 photos for SD14/Rebel XT/D40).
4. Some Sigma lenses haves quality control issues. I had to return the 30mm f1.4 lens because of back-focus problem. It has worked fine after the exchange. Sigma USA customer support is friendly.
5. Camera system crashes a bit too often. Need to restart and waste 2 seconds every time.
6. Slower burst rate. Not suitable for shooting birds or race cars unless you are really good.
