Moving Forward: Digital Camera Reviews at AnandTech
Digital SLR cameras have come a very long way in a very short period of time. They have gone from very expensive instruments affordable only to corporations and professionals to the fastest growing segment of the imaging market in only a few short years. Many of the early problems like low resolution, slow startup, slow saves of images, high energy requirements, and bulky batteries have all but disappeared. The fairest measure of the state of Digital SLR cameras is that today they are not much different in appearance and function than the last generation of film cameras. In general, however, they offer even more electronic sophistication than the film cameras they replace.
Recent digital SLR cameras are capable of 1000, 2000 or even more images on a single battery charge. Digital SLRs are also getting smaller in general, and now average even smaller than the last generation of film SLRs. Despite the decreasing size, many camera makers are paying much more attention to ergonomics - how the cameras feel in the users hands - and the smaller digital SLRs handle very well.
For all of these reasons you will find many more digital SLRs than point-and-shoot cameras in future digital camera reviews at AnandTech. This is because the digital SLR is now the fastest growing segment of the digital camera market, and that is where most of the new camera introductions will happen. This does not mean we will ignore the digital point-and-shoot, as there is always a place for a small, pocketable, and reasonable digital camera. It does mean AT will pick more carefully among the point-and-shoot cameras we will choose to review.
The Sony Alpha or A100 and Nikon D80 are already planned for review. They are the first of the new breed of affordable (under $1000) 10 megapixel SLR cameras. We will also review the other announced members of the 10 megapixel club - namely the Canon Rebel XT1, Pentax K10D, and Samsung GX-10 - when they become available in the market. As stated at the beginning of this guide, we really need your help in deciding how to test these cameras.
Many of the tests used at photo websites have very little real relevance to the digital SLRs of today. Start-up and shot-to-shot times are all but instantaneous with the latest models and even those fast times continue to improve. Virtually none of the lags of early digital cameras remain, and the response time no longer reminds you that you are using a digital SLR camera. Since SLRs have interchangeable lenses there is no fixed lens to review and every major lens line has some incredible lenses and a few dogs. Do you want us to test the standard kit lens in our upcoming reviews or should we use a standard quality lens for all tests in that line like a 50mm f1.4? Or both?
What tests would you like to see in the digital camera reviews? This is your time to sound off. Resolution targets are available and it is fairly easy to determine resolving ability of the kit or a standardized lens. Would these be useful to you in our reviews? There has also been the suggestion that we shoot a standard scene (the same scene) in every review so readers can compare fine details like color balance and resolution. If you want that let us know. We are open to new ideas and new ways of examining digital cameras in AnandTech reviews. We have a different audience than the photo websites and we want our reviews to provide you with what you are looking for.
We sincerely hope you enjoyed our overview of digital photography, with a slant toward the digital SLR. It is our belief that, in contrast to computers, many readers at AnandTech don't know a lot about photography and digital cameras. Some of you are very knowledgeable, but our letters indicate many more readers have been shopping for digital cameras with little understanding of how they work or what to look for. The purpose of this Guide from 20,000 feet is to provide a broad overview with enough specifics to help our readers become better shoppers for digital cameras in general and digital SLRs specifically. If we helped in that arena please let us know in your comments. If there are additional articles on digital imaging you would like to see in the future we would be happy to hear your suggestions.

Is providing a single sentence regarding start-up time dwelling? I don't think any camera review is complete without listing startup times and listing shot to shot time. I think it's a bit hypocritical to focus on core architecture, timings and such and then say a length of time I can actually perceive is not relevant. Especially, when you go and provide such a good article. I think you are just trying to make the other review sites seem stodgy and backward or just wrongheaded, and show that AT is "with it". Moreover, you say they speak gibberish like they are jargon slinging photo elitist snobs. Then you provide,IMO, a pretty techical primer, when they probably have some material for novices too. I know you were just saying "We're Cool, We Rule!", but I don't think when ur AT you have to do that. AT is already in my RSS reader because it does quality reviews. I just skimmed the article, and I can't wait to go back and read it in depth. I'me really excited about AT doing photo stuff too. I agree with the above poster that finding some standard meaningful benchmarks with good subjective commentary will have AT ruling the roost in camera reviews. Not to plug another site, but I think Steve's Digicams provides excellent reviews, actually his site is about the only site I really find useful for cameras. I'm glad I will soon have two sites that provide good information. YAY AT!soydios - Monday, September 25, 2006 - link
How does AnandTech review and compare its computer components? With standardized benchmarks and editorial commentary. Compare all the cameras with a good, strong set of standardized tests across the board, and also add a dose of the editorial commentary.In particular, for the sub-$1000 market, I would suggest evaluating the kit as a whole (image quality with kit lens). Personally, I will be picking up a Nikon D50 with the 18-55mm and 55-200mm lenses, and I have researched the heck out of that package, trying to find an AnandTech-esque review.
Venturing above the sub-$1000 (although I would be very intrigued by some reviews of the professional-level equipment) would get very expensive very fast. Perhaps start small, then venture into the almost-pro market (Nikon D200 and Canon EOS 30D, and some of the $500-$1000 lenses), then maybe dip a toe into the professional level, just to let us all see what the real fancy stuff is like (since very few of us will be buying a D2Xs or EOS-1D MkII-N).
Time permitting, I would put out some quick looks at the Nikon D50 and the Canon EOS 350D, with some comparison between the two. A review/comparison of both the Nikon D80 (in the works, good!) and the Canon EOS 400D would be an interesting read.
Again, review the D-SLR market the same way you guys do computer hardware. Avoid the slugfest low-range and the stratospherically-priced high range. Focus on the high-midrange market (the sub-$1000 D-SLR's to start, move up to the $1k-2k market once you gain some feel for differences between cameras). Do across-the-board standardized benchmarks, with some synthetic but more real-world results.

Exactly my thoughts. I have spent some time at a number of camera review sites and am always left wondering "Is the Nikon D80 good enough to justify the price difference over the D50?". "What about the Canon EOS 30D? How much better is it then the Nikon D80 or the Rebel XT/XTi?"Maybe these cannot be answered in the same way as CPU and GPU articles, but standardized tests and comparisons would be nice.
Give me some numbers! I don't want to hear "shot-to-shot performance was sluggish compared to higher end cameras"...unless you can quantify that for me.
Lighting is such an improtant part of photography. Standardized indoor lighting under a couple different kinds of lighting situation (i.e. low, bright, fluorescent, etc.). I don't know how to standardize outdoor shots, but it sure would be nice.

I'm gonna stick with www.dpreview.com for now if I want to get my digital photography news/articles.AT, stick with PCs, will you?

I don't understand as I usually read more than one site on one subject. For instance I've been reading Tomshardware since it was sysdoc.pair.com and both Anandtech and Extremetech nearly as long.jnmunsey - Monday, September 25, 2006 - link
Geez, you'd think a site like Anandtech would find someone who knows what he's talking about to write this article...soydios - Monday, September 25, 2006 - link
I'm just a photography hobbyist, but I thought that the article covered all the important basics of full-manual general photography and digital photography.I would touch on filters, though. Those can come in handy. Particular onces to focus on: UV ("does it actually do anything, or is it just a lens protector?" debate), Polarizing, and the primary colors (blue, yellow, and red).
soydios - Monday, September 25, 2006 - link
Concerning polarizing filters (I really wish there was an edit functionality for comments): circular polarizing works with autofocus and digital cameras, linear does not.I know AnandTech isn't much of a software website, but a short article on editing software (Adobe Photoshop, beta of Adobe Lightroom, Apple Aperture) would complete the picture. No need to focus on the software or printing, but a photography software article written in the same manner as this one is something that would help me a lot! (I have almost no experience with editing software).

We all want to improve, so please provide specifics so we can address them. It would also be helpful if you would provide your photography credentials, so we can know the level of expertise to attach to your comments.kilkennycat - Monday, September 25, 2006 - link
... a first-class and technically-meaty summary of the current status of digital camera technology. Well up to the usual Anadtech standards. Congratulations, Wes. The addition of a Digital Camera section is a superb idea. By all means, use reference charts, lighting and scenes for resolution, optical-distortion, shading and color-fidelity comparison of both lenses and sensors. Just as you have with video cards and CPUs, come up with your own benchmarks if necessary.
