At these sizes, maybe any differences are impossible to notice. The 60D felt fantastic in my hand. I could justify the additional cost of the 60D based on. When I was all set to order the T2i, one approach I was planning to use for football shots was to extract single frames of video and use those as stills. If that seems like a valid idea, then I guess the faster burst of the 60D is not that important. Has anyone else done any serious looking at the image quality between these two?
I have read many comments about the kit lens. Does anyone have any comments about the kit lens? Is it worth the hefty price tag? We take a look at the Cine, the high-end model in this series. The Nikon Z9 is the company's first camera to feature a stacked CMOS sensor, which brings a raft of new features, including blazing speed and autofocus performance to the Z lineup. Click through for our detailed first impressions of Nikon's latest professional ILC.
The Sony a7 IV is the fourth generation of the company's core a7 full-frame mirrorless camera model, and it's the most advanced yet. Click through for an in-depth look at Sony's latest full-frame mirrorless ILC.
Nik Silver Efex Pro 3, one of the standout components of Nik Collection 4, is a black-and-white conversion tool that goes far further than the grayscale or black-and-white tools built into all-in-one photo apps. For some users, this app alone might be worth the cost of the whole collection — find out for yourself in our review.
The Nikon Z mm F2. Get all the details in our full review. These capable cameras should be solid and well-built, have both speed and focus for capturing fast action and offer professional-level image quality. Although a lot of people only upload images to Instagram from their smartphones, the app is much more than just a mobile photography platform.
In this guide we've chosen a selection of cameras that make it easy to shoot compelling lifestyle images, ideal for sharing on social media. If you're looking for the perfect drone for yourself, or to gift someone special, we've gone through all of the options and selected our favorites.
We looked at cameras with selfie-friendly screens, wide-angle lenses, microphone inputs and great video quality, and selected the best.

Apr 21, Unfortunately, this also filters out a lot of the red color that comes from hydrogen-alpha emissions in red nebulae. Humans have a little bit of visual sensitivity at the hydrogen-alpha emission line of This extra sensitivity gives images more of a red color, especially in skin tones.
So manufacturers filter most of it out. This is good for normal daytime photography, but not so great for astrophotos of red emission nebulae. Amateur astrophotographers have been dealing with this problem by modifying the long-wavelength filter. They either remove it completely, or substitute another filter that passes almost all of these hydrogen-alpha wavelengths. This is good for astrophotography, but slightly skews normal daytime colors.
This can easily be compensated for by using a replacement filter such as the Xnite CC1 Color Correcting filter and by using a custom daylight white balance. In Canon came out with the EOS 20Da to address this problem in a stock camera specifically designed for astrophotography, but one that would also give good color for normal daytime photography. The long wavelength filter in the 20Da transmitted more of the hydrogen-alpha wavelength, but still not as much as a modified DSLR.
The long-wavelength filter in the 60Da transmits 1. There is a lot of interest in Canon's 60Da astrophotographic camera and questions about how it performs for deep-sky astrophotography of red emission nebula compared to a non-modified camera, as well as to a stock camera that has been modified.
Several different targets were shot in a couple of different ways to compare the performance of these cameras for long-exposure deep-sky astrophotography. In Figure 1 at the top of the page, we can see the results of imaging M27, the Dumbbell Nebula. As a planetary nebula it is an interesting test object because it has a lot of cyan blue-green oxygen III emission in it as well as some red hydrogen-alpha emission nebulosity.
The results in Figure 1 are pretty much what we would expect. The stock 60D records a lot of blue-green oxygen III because that is around the wavelengths that human vision is most sensitive to, and so the camera is designed to approximate this as closely as possible. It only records a little bit of red hydrogen-alpha compared to the 60Da and the modified T2i D.
In addition to the same amount of oxygen III recorded, the 60Da records a lot more red from the hydrogen-alpha emission. This is also expected. The replacement filter passes almost all of the hydrogen-alpha wavelengths, whereas the 60Da is still filtering some out. It is also interesting to compare the signal-to-noise ratio in the images produced by these three cameras as we can see in the chart below.
The same small area of background sky, containing no stars or nebulosity, was measured in Photoshop. The signal-to-noise ratio was computed by dividing the mean pixel value in this area by the standard deviation. As expected, the modified T2i D has a slightly higher signal-to-noise ratio than the 60Da. Both the modified T2i D and 60Da have a better signal-to-noise ratio than the stock 60D.
This is because the T2i D and 60Da transmit more light at the longer wavelengths. These wavelengths produce photons which pass the filter and are detected by the sensor, and turned into signal.
The signal-to-noise ratio is higher in the T2i D and 60Da simply because there is more signal present. Buy the Canon T2i Search on Amazon. Read our Canon T2i Full Review. Read our Canon 60D Full Review.
