Sony A200: Entry DSLR Roundup

With all the press and excitement in the past few weeks over $3000 full-frame Digital SLR cameras, it is easy to forget that many buyers are looking for the absolute best "bang-for-the-buck" in a camera. There is little doubt that you will find that best value today in interchangeable lens DSLRs that now offer almost all of today's checklist features starting at a $499 street price.
So what do you get for your $500 these days? To answer that question we took a closer look at Sony's lowest-priced DSLR. The Sony A200 sells complete with a Sony 18-70mm (27 to 105mm equivalent) lens for just $499 - sometimes even less. The A200 also features body-integral image stabilization, which means the IS will work with any lens you mount. Sony does not include Live View in the A200, choosing instead to feature Live View only on the A300/A350, which use a uniquely easy to use and useful Live View compared to competing models.
The only competition in the $500 arena is the Olympus E420 which sells for around $530 with the 14-42mm (28-84mm equivalent), and the recently reduced Canon XS with a current street price of around $525 with an Optical IS 18-55mm lens. The E420 is the smallest mirror DSLR on the market. However, it is now the only camera in its class to not offer some form of IS - either in the camera body or by including a kit lens with IS or VR built-in. You will have to move up to the E520 at $100 more for IS in the body. The E420 does feature Live View, a feature pioneered by Olympus, including both phase-detect and contrast-detect options. The Canon XS also includes both Live View options.
The DSLR "entry" market also includes the next rung at a $599 street price with lens. This adds the Nikon D60, Olympus E520, Pentax K200D, and Sony A300. All five sell for a street price of $599 with an 18-55mm or equivalent kit lens (18-70mm for the A300). The Pentax, Olympus, and Sony feature body-integral IS that works with any lens and the Canon and Nikon kits include a stabilized kit lens, but still require IS or VR lenses for the IS feature.
Clearly this has become a very crowded market segment, which is great news for buyers. In the $499 to $599 price range you now have a choice of no less than seven models from the top five DSLR manufacturers. With such a wide selection there are a lot of models competing for your attention and that can lead to even better prices. Today we will take a closer look at the Sony A200, which is arguably the lowest priced "full-featured" DSLR you can buy today. Does this price-leader also bring true value to the DSLR market?

Those coming from P&S who insist on Live View would probably be happiest with the Sony A300 ($599 kit) or A350 ($799). If they want a fast-focusing capable traditional DSLR the A200 has a fast 9-point module that works well with off-center targets, tracks moving subjects well in sports and kid shooting, and is one of the fastest AF and largest brightest viewfinders in its class.When the new Panasonic G1 micro 4/3 hits the shelves it features a sensor with truly fast contrast-detect AF that many users will find very satisfying in Live View mode. It is the first contrast Live View we have seen that is likely to satisfy DSLR fans. It is likely the first of a new generation of fast Live View sensors that will be used in future competing DSLR cameras.

the wireless flash controller will also work with Sigma, Vivitar etc. flash guns too so you can certainly get down to at least 1/2 the price of a 42AM. I agree that it's probably a function not used y the majority of A200 users but some people who may might use the A200 as a 2nd/backup body to e.g. an A700.The A200 doesn't have live view & other than the A300/A350 with their particular & unusual implementation autofocus in live view is pretty poor (slow) on DSLRs. At any rate A200 autofocus is as good as (or better than) any other DSLR in it's price bracket.
remember that most p+s use contrast detect AF whereas DSLRs use phase detect (other than in live view except A300/A350).

I have noticed the Sony a200 review on dpreview dated July 2008 with an announcement date of January 2008. you can view it here.http://www.dpreview.com/reviews/specs/Sony/">http://www.dpreview.com/reviews/specs/Sony/
Perhaps there are changes I am unaware of.
This does appear to be a nice camera for the money. It has a good size sensor along with a decent kit lens.
Is it true the future is in cmos sensors?
What is the expected life span of CCD/CMOS sensors?
Wesley Fink - Monday, October 20, 2008 - link
CMOS sensors are cheaper to manufacture and it is much easier to integrate associated electronics into a CMOS sensor.It is worth mentioning, however, that the newest highest-res mid-size Kodak sensor, used in the new Leica Medium Format camera, is a CCD sensor, and some still claim the CCD to be superior in image quality.
For a more in-depth discussion of CCD vs. CMOS you may want to look back at our Digital Sensor Articles with Part 1 at http://www.anandtech.com/digitalcameras/showdoc.as...">http://www.anandtech.com/digitalcameras/showdoc.as... and part 2 at http://www.anandtech.com/digitalcameras/showdoc.as...">http://www.anandtech.com/digitalcameras/showdoc.as....

Thank you for your prompt reply.I took the time to read both the articles. They help in understanding the differences between CMOS/CCD sensors. Yet everything electronic has an expected lifespan. Does anyone have an expected lifespan for these sensors?

Looks to me like the lenses you are using are scratching the limits of the sensors, thus the results are all pretty much the same. Using a prime at f/8 will pretty much take the glass out of the comparison as most any prime is quite sharp at f/8 unless there is something wrong with it.Also please test using a subject with more colors so we can see how each camera handles demosiacing under increasing ISO.
Thanks for you hard work.

As stated on the test pages all the test shots used a 50mm f1.4 prime stopped down to f/4.0. We are down 3 stops from the rated speed and in all cases the glass is in its highest resolution range.The only exception to this is the Olympus tests, where we use a 35mm prime macro lens stopped down to f4, which has been tested to be in the highest resolution area of that lens.
This is because of the 2x factor on Olympus which gives us a 70mm equivalent. That is much closer to the 75- 80mm equivalent of the 50mm on the 1.5X-1.6X sensors. The 50mm macro on the Olympus would be equivalent to 100mm.
Test results are closer because other manufacturers have made dramatic improvements in their sensors in the last couple of years. Canon no longer enjoys the massive lead in sensor resolution and low noise they enjoyed with their CMOS sensors in the early years of DSLR technology. As pointed out in the test comments, many of today's competing cameras in the entry category use the Sony 10.2 megapixel sensor so results would be similar.
The biggest differences are detailed on page 9 in the comparisons of the 3 Sony sensors used in the A200, A350, and A700. The new 24.6 megapixel A900 could have been included as we have one in house, but it seemed a stretch to include a $3000 camera with resolution more than twice the entry-level DSLRs.
As Jarred has pointed out we always use the kit lens for sample images that are normally included in our reviews, so photos will be representative of what a normal buyer might expect. We similarly always use primes stopped down to the same f/4 for our noise and resolution tests to remove glass variations from the equation.

The reasoning to use primes is NOT to test lenses but to try to eliminate lenses as a variable during testing and atually see how the bodies perform. By using less than very good lenses it's hard to tell what is limiting performance, the lens or the body.Since you are not testing scenes with any depth of field just use the sharpest setting, which is f/8 for just about any lens. f/4 would be applicable to test bokeh for a depth of field shot.
Again I know it's easy to complain. But really I'll I'm saying is use primes and stop down to f/8 so we can isolate the camera body performance.
Thanks,

According to photozone.de, the center resolution of the 50 1.4 is essentially constant from f/2.8-f/5.6, and down a bit at f/8 (corners top out at f/5.6).http://www.photozone.de/canon-eos/159-canon-ef-50m...">http://www.photozone.de/canon-eos/159-c...mm-f14-u...
slrgear calls f/4 and f/5.6 essentially tied, with f/8 a little worse.

Both of these tests are on an 8MP sensor, and the center resolution numbers are pushing the boundary of that sensor, so larger differences might be revealed in tests with a higher resolution sensor. For the 10MP sensors though f/4 would seem to be a very valid choice.

You know that 50 1.4's are not very good, even stopped down a couple of stops.I would choose the Olympus 35mm macro for quality over the 50's. Try a 50 or 60mm macro instead. It's about as close as you're going to get to the 35mm macro in quality to even out the lens issue.
