Feature: Sony Alpha100 is putting pressure on Nikon and Canon top end SLR cameras Sony has had a line of digital cameras that have garnered rave reviews. For awhile , Sony's Mavica was the major player in small to medium size digital cameras. But Nikon, Canon and others won the day with cheaper and faster storage using Flash memory cards and small but reasonably high quality 3 to 4x optical zoom lenses (the quality of pumped up digital zoom having been found wanting). And in the digital SLR field Canon own an over 50% market share with Nikon at 30% plus. So when Konica-Minolta exited from both the film and digital field an opportunity was presented. Sony in the electronics marketplace is not only an innovator but also a persistent player. So when Konica Minolta signaled it wanted to exit from digital cameras, Sony seized the opportunity to buy the rights to the Konica Minolta Maxxum camera and lens lines. Astutely, Sony decided to use that already very good technology as a springboard for its new digital SLR cameras. And the benefits show. First impressions were light, learning, and works well. The Alpha weighs slightly more than 1 pound body alone. But even equipped with battery, micro-drive and the new Sony Alpha 18-70mm zoom lens, I was amazed how light the camera was. This is no small benefit to a sport photographer carrying 3-4 lenses and 2-3 bodies and 5-8 batteries. Also appreciated is the long-life Stamina battery - able to take 750 on a single charge. Typically that is a days work for which I carry 3 batteries right now. The Sony salesman insisted the battery had not been recharged all day. Next when Sony claimed it had no limits on 10MPixel JPEG images taken at 3 frames per second - I was skeptical. But this would allow me to test two birds (battery life and real speed shooting capabilities)with one stone. So when offered I gave it a real stress test whirl. Pictures of the dragonboats going by at 3 frames per second. Several bursts of twenty seconds or more quickly had the 512MB card filled. So I erased the images and cut the image's recorded size by 4 =>down to small (1920 x 1280 pixels = 2.5Mpixels). 350 images later in about 10-15 minutes of shooting I had barely dented the Stamina battery's left-over power setting. Now the bracketed shots would start to tail off after 15-20 seconds of shooting. But when I looked at the images there was no perceptible change in quality and even the sequences at the end of the burst seemed to have the same interval as at the beginning. So now the Sony Alpha had my attention. Unfortunately, I did not have the time as the Dragonboating Premier Open Finals were just about to commence. And kick myself in the ass, I did not get the images downloaded or transferred to my own compact flash card (saving weight I had not brought my portable hard disk that day). So all the rest of this review will involve the research work I have done in the interim to find out what's up with the Sony Alpha. Sony Alpha Specs The grabber specs on the Sony Alpha are three - in camera image stabilization, Sony calls it Super Steady Shot Inside; the 10.5 MPixel CCD sensor; and the High Speed Image processing system. Image stabilization has long been present in video cameras and has started to come to digital SLR cameras at the $2000++ highend. Sony brings about 3 to 4 extra stops to handheld situations in which the lighting is low or telephoto lenses are being employed. This means that with stabilization on photographers can use their 500mm telephoto with shutter speeds of 125 (or 1/125th of a second). To add to the good news, I was able to take images at 400 and 800 ASA that simply were very attractive to this Nikon and Canon SLR veteran. But equally important for us deliberately-blur-through-slow-shutter-speed fans (there is a whole world of suggested motion at 1/20th to 2 seconds for all you photo artists) - one can turn off the Image Stabilization and catch implied motion.10.5Mpixels does not seem like a lot - and given the intro of Canon's new XTi Digital Rebel and the Nikon D80 at the same 10.5Mpixels range, the wind seems to be taken out of the Sony sails. However, there is one thing I noticed in the shots I was taking with the Alpha100, no vignetting especially at the wide angle settings that I see with my 8mPixel Digital Rebel. Also this is the same 10.5Mpixel sensor that Nikon uses in its $2000 D200 camera. High Speed Image Processing, almost unlimited 3 frames per second, is very attractive for news and sports photographers. Covering the World Lacrosse Championships and Molson Indy taught me the value of being able to power shoot and bracket at least 4-6 shots on a scene. Clearly the Alpha100 is equal to that task and more. The 3 Sleeper Features of the Alpha100 The EyeStart System pre-triggers the auto-focusing as soon as you bring your eye up to the view finder. What's the advantage ? It used to be the delay between clicking the shutter release and getting the camera ready to shoot. Now that delay is primarily due to the new auto-focusing features, so the Alpha has a proximity sensor in the viewfinder and it starts the autofocus as soon as your eye approaches the viewfinder. Net result - less delay in getting quick shots off. Some Rough Edges During my extended trial shooting session with the Alpha100 I was impressed with its light weight and good feel. But I did not like the internal clutter when looking through the viewfinder. The focus lines and cubes just seemed too dominant. And the layout of the control info was a bit confusing - chalk it up to lack of familiarity with Alpha's controls. But along with the LCD back I was fumbling to control some basic settings like white balance and even image size. You can see that this party does not enjoy the prospect of going through the digital camera operations learning curve again. Summary Sony is usually the premium priced spread and there are many premium features some not even yet mentioned like Dynamic-Range Optimizer and BionZ image processor engine able to do so much for image processing. For Minolta and Konica camera users plus those going to digital SLRs for the first time with no lens investments, the Alpha is a no-brainer. For Canon and Nikon users - take a look, Sony is offering a $500-1000 discount on their premium digital SLRs. (C)JBSurveyer Home 4 Strikes Against Digital Photography |
