Canon EOS 50D Review
While the Canon EOS 5D Mark II has been getting all the hype since it’s release. However, the 50D which came out about the same time has been getting virtually zero publicity because of it’s bigger brothers full-frame sensor and video capabilities. So let’s take a good look at the EOS 50D and see if it is really worth an upgrade or if its just a minor refresh of the previous 40D.
The Canon EOS 50D is a 15.1 megapixel DSLR with an APS-C sized sensor. The 50D is available in a body-only or as a kit with a 28-135mm f/4-f/5.6 IS lens. If you are getting into a DSLR for the first time, the kit lens is actually a really nice general purpose lens which, by itself, sells for $410 making the kit with the lens a really good bargain.
As already mentioned, the 50D features 15.1 megapixels, built-in sensor cleaner, ISO ranges from 100 – 6400. Besides some better overall specs, what really makes 50D different from previous models is the high resolution LCD display. With a large LCD with high resolution you can really see when an image is clear and sharp. Another enhancement over previous models is face detection when in Live View mode to help focus on individual faces.

While you can certainly take the camera out of the box and start shooting, I will run through the setting changes that I did and why.
C. Fn I : Exposure
Custom Function 3 changed to 1 to enable ISO expansion. This is needed to shoot at ISO ranges above 3200.
C. Fn II : Image
Custom Function 3 changed to 1 to enable Highlight Tone Priority. This enables Highlight Tone Priority which can help from overexposing important aspects of your image. Note however that when this is enabled, you will not be able to go over ISO 3200 regardless of the previous setting.
C. Fn III : Autofocus/Drive
Custom Function 3 changed to 1 to enable Multi-controller direct. This option enables you to select the autofocus point by using the multi-controller (mini joystick).
Live View Function Settings
Live View Shoot set to Enable to allow for Live View mode
Expo. Simulation set to enable so the LCD show how the exposure will look when the shot is taken
Grid Display was set to the rule of thirds overlay
Image quality was set to RAW.
Highlight Alert was enabled in order to show â€œblinkiesâ€ on the LCD to show overexposed areas
Finally, I made sure the date and time was correct, dropped in a compact flash card, formatted it and I was ready to go.
Using the EOS 50D
The first thing I get asked is “How good is the ISO performance?” so let’s start there. By default the 50D can shoot ISO 100-3200. If you enable ISO Expansion then you have ISO 6400 (H1) and 12800 (H2). However, just because you CAN go up to ISO levels like that doesn’t mean it really usable. The following image demonstrates the ISO performance from ISO 800 – 12,800.
As you can see, the ISO performance even up to ISO 6400 is actually pretty usable. Keep in mind that no noise reduction software was used to create this image, this is right out of the camera. Even some basic noise reduction will clean up the ISO 6400 images while the ISO 12,800 images would require some significant noise reduction to really make them usable.
Differences from the 40D
After the ISO question, the second most common question is “Is the 50D worth upgrading from the 40D?” so let’s compare a few key features between the two:
|10.1 megapixel||15.1 megapixel|
|Live View||Live view with Face Detection|
|sRAW Mode||2 different sRAW modes|
|ISO 100 – 1,600||ISO 100 – 12,800|
|230,000 pixel display||920,000 pixel display|
|RCA video output||RCA/HDMI video output|
While not everyone will need the new features, I certainly think that many people who are more serious shooters like wedding photographers will really appreciate the high ISO performance, the larger megapixel count and the high resolution display. Those are certainly the key selling points for me.
50D Coolness Features
We have already looked at some of the biggest of the 50D’s features but there are a number of features hidden in the 50D that are actually pretty cool even if they don’t make the short list that everyone talks the most about.
- Peripheral Illumination Correction: This feature corrects vignetting that happens with certain lenses
- Live View Enhancements: Two different focusing modes are now available as well as a new face detection system for locking focus onto faces.
- User Settings Modes: Two modes on the main dial allow you to create two custom modes for your custom settings.
How big are the images?
Well, they are pretty big. The following chart shows typical sizes for the different quality modes:
Coming from using a 30D (8 megapixel) this means that my storage requirements have just doubled.
Does it take good images?
Of course it does. Here are some samples:
The 50D Controversy
There is quite a lot of debate about the sensor’s pixel density and how the smaller pixels and density are a recipe for more noise. While this is a very hotly debated topic a lot of it depends on your shooting situation. You will most certainly see extra noise in areas of images that are underexposed while if you are shooting well, or slightly overexposed images you can really move up into the higher ISO ranges. As we have discussed in previous articles, digital sensors loose detail in underexposed areas while maintaining more detail in overexposed areas, thus its safe to slightly overexpose to help reduce noise and maintain detail. A good rule of thumb is to overexpose by 1/3 – 1/2 of a stop, even more if you can without clipping. Learning the nuances of how your particular camera works and where it’s unique “sweet spot” is will help you to get the best images from your camera.
Is the 50D the best choice for you?
You are the only one that can decide if any particular piece of equipment is the right choice for you. What I did was to rent the body from Borrowlenses.com for a week to really put it through its paces and do some major comparisons. After using it in a variety of conditions, I knew it was the right choice for me at this time.50D, canon, DSLR, eos, ISO, noise, raw, Review, sensor
