This review is close to 10 pages long because it was written for people who are not proficient with the terms and concepts used in the DSLR world. If you are a proficient DSLR user then I would recommend that you check one of the much shorter reviews here or dpreview. For example, you already know what vignetting is and therefore understand the importance of the new lens peripheral illumination correction feature. However, a new DSLR buyer does not know what this means and this is why I therefore explain what each feature really is so these people can then decide if the feature is really important to them.
If you have not done so as yet, be sure to also check out my reviews of the Canon 7D and Canon 40D as well.SECTION 2: INTRODUCTION
It has been just over a year now since I purchased my Canon 40D. At the time, I was just beginning to take my photography really serious. Since then, a lot has changed. I have now become a semi-pro. I still have my full-time job as an IT Manager here in Miami. However, I do a lot of photography work, especially events, on the weekends.
I really love my 40D but as I started doing more and more professional work I realized three things:
1. I needed a second camera body
2. I needed a camera with a more professional focusing system.
3. I needed a camera with even higher ISO performance
It was rumored back then that the replacement for the Canon 5D would be out in the first quarter of 2008. I decided to wait for it. However, when the time came there was no news from Canon about the 5D replacement. This was back in March 2008. The Nikon D300 had now been out for a while by then. I thought about buying it but I decided to wait until it was fully reviewed by dpreview as I wanted to see if Nikon had really finally addressed the high ISO performance issues. I ordered it one day after it was reviewed by Phil Askey on dpreview.
Since then, I have been using both the Canon 40D and the Nikon D300. I know it is a bit of a strange combo. People are always surprised when they see that I am using a Canon and a Nikon together.
I took all three cameras - Canon 40D, Canon 50D and Nikon D300 - over the weekend to the Miami Seaquarium to see how the new Canon 50D compared with both of them. SECTION 3: NEW/CHANGED FEATURES
A. High-resolution LCD Screen
The LCD screen is still 3 inches. However, Canon has now increased the resolution from 230,000 dots to 920,000 dots which is the same as that found on the Nikon D300. Of course, this makes it a lot easier to check images on playback to see if they are sharp and in focus. More important, however, is the fact that Canon added a two layer anti-reflective coating which makes it way easier now to review images in bright sunlight. It is a lot easier to review images on the Nikon D300 than the Canon 40D. However, the Canon 50D definitely surpasses the Nikon D300 when reviewing images in bright sunlight.
B. 15.1 Megapixel CMOS Sensor
I think the MP increase is the biggest surprise to me since Canon has always been conservative when it comes to this. However, this increase now seems to be the trend as the new Canon EOS 5D Mark II has gone from 12 MP to a whopping 21 MP. I was always puzzled by the fact that the baby Canon Rebel had more MP than its big brother.
I can clearly see the difference in the resolution of the images produced by the 15.1 MP Canon 50D and those from the 10 MP Canon 40D. For a casual shooter this is not a big deal. However, for professionals shooting events this is really useful. Whenever I shoot an event I try not to turn it into a photo shoot. People are there to have fun. That is the first priority. I need to be able to get my shots fast. Many times this means getting the shot and then doing some cropping to make it perfect. Having 15 MP to play with can be a life savior here. Of course, if I only did portraits where I have time to pose my subjects this would be less important to me.
There is a small difference in the resolution of the images from the 15.1 MP Canon 50D and the 12.1MP Nikon D300. C. High ISO Performance
The ISO setting control how sensitive the image sensor is to light. As the light gets lower you can increase the ISO to avoid using the flash. This is really important when you want to shoot in available natural light such as at dusk or at dawn when the light is really beautiful. Another example is when you want to photograph a bride and groom during the first dance without using the flash so you capture all the romance. The downside to increasing the ISO is that the resulting photos will tend to get grainier as the ISO increase.
The Canon 40D allowed me to go to ISO 1600 and then expand it to ISO 3200. When I just started out doing casual shots this was okay. However, I find that I often needed to go higher than 1600 and of course I was forced to use ISO 3200. On the Nikon D300 I could go all the way up to ISO 3200 standard so if I needed to use anything higher than ISO 1600 I would use the Nikon D300. That way if I only needed ISO 2000 I could use that setting rather than use ISO 3200. I must let you know that Nikon did fix the high ISO performance issues that plagued its DSLRs prior to the Nikon D300.
The Canon 50D now comes with a standard range of ISO 100 to 3200 just like the Nikon D300. However, the concern that I had was that with the big increase in MP count there would be much more noise (grain) at the higher ISOs. The more MP you have the more noise you tend to get at higher ISOs. I would have much preferred a smaller MP count and better high ISO performance. However, the engineers at Canon have really outdone themselves this time. The high ISO performance of the Canon 50D is just as good as the Nikon D300 even though it has 3MP more. Much of this is due to the fact that Canon is now using gapless micro lenses on the image sensor. This seemed to have really increased the light gathering capabilities of the pixels.
The Canon 50D ISO can be expanded to 6400 (H1) and 12800 (H2). The Nikon D300 can only be expanded up to 6400. However, on the Nikon D300 you can go from 3200 to H0.3 and then to H0.7 before you get to H1.0 which is 6400. This is more flexible than having to go straight to 6400 since you should generally try to use lower ISO speeds.
You might be thinking that it is absurd that anyone should want to use ISO 6400 and worse ISO 12800. However, there are times when getting the shot is more important than the quality of the shot itself. A good example here is when shooting sports. If the light becomes very bad for whatever reason you will need to increase your ISO as much as possible to get high enough shutter speeds to freeze the action.
D. Auto ISO Range (100 to 1600)
I have been to Butterfly World on several occasions to get photos of butterflies, birds and the tropical plants there. It is normally very sunny so to save time I shoot in Aperture priority mode. This allows me to simply set the aperture and then let the camera automatically set the shutter speed based on the current ISO and aperture settings. One thing about South Florida is that one minute it can be very sunny and then in just a few minutes it can become real cloudy. The problem this pose is that when it becomes real cloudy the shutter speed selected by the camera can be so low that it would result in camera shake which in turn results in blurry images. When I just started out my photography this actually happened to me as I would simply forget to check the shutter speed that was selected by the camera.
The auto ISO feature lets the camera automatically change the ISO to suit the shooting mode. For example, when in aperture priority mode if the camera detects that the shutter speed selected would result in camera shake it automatically increases the ISO. This feature is available on the Canon 40D. However, the maximum ISO it would automatically set is 800. The Canon 50D will now set ISO up to 1600 which is a lot more flexible.
The Nikon D300 actually takes the auto ISO concept further by allowing you to set the maximum ISO you want the camera to set and the minimum shutter speed you are willing to work with before the camera start to automatically set the ISO. This gives ultimate control to the photographer.E. Burst Buffer
Another concern I had with the big increase in MP count was the impact it would have on the burst rate. With the MP count going from 10 to 15 this would normally result in a much slower burst rate. However, the new DIGIC IV image processor is a lot faster than the previous DIGIC III processor so the burst rate is pretty much the same at 6.3 frames per second from 6.5 frames per second. If you use a UDMA card with the Canon 50D you can buffer up to close to 90 large/fine JPEGs versus the 75 on the Canon 40D. The Nikon D300 can store up to 100 large/normal JPEGs at a burst rate of 6 frames per second. With the optional MB-D10 batter pack you can get 8 frames per second. F. Lens Peripheral Illumination Correction
It is just a fact of life that the light entering a lens tends to fall off around the edges. This tends to be more pronounced when the lens is wide open. The resulting photo will appear dark around the edges. You will see it sometimes referred to as Vignetting. It is more common on cheaper lenses. However, even the most venerable and expensive lenses are not immune to this problem. I have sometimes seen it on my professional grade lenses such as the Canon 100-400mm f/4.5-5.6 L IS lens and even the Nikon 70-200mm f/2.8 G lens.
