If you are wondering about how to calibrate lenses, this article has detailed explanations and different methods of AF fine tuning. Due to the nature of the phase detect autofocus system that is present on all SLR cameras, both cameras and lenses must be properly calibrated by manufacturers in order to yield sharp images. Various factors such as manufacturer defects, sample variation, insufficient quality assurance testing/tuning and improper shipping and handling can all negatively impact autofocus precision. A lot of photographers get frustrated after spending thousands of dollars on camera equipment and not being able to get anything in focus. After receiving a number of emails from our readers requesting help on how to calibrate lenses, I decided to write this tutorial on ways to properly fine tune focus on cameras and lenses. Lens calibration is a complex topic for many, so my goal is to make this guide as simple as possible, so that you could manage the process by yourself, while fully understanding the entire process. In addition, I strongly recommend to follow these tips every time you purchase a camera or a lens in order to identify and address any potential focusing issues. But I have to warn you – this article is NOT for beginners. If you just got your first DSLR, you might get very quickly frustrated with the calibration process.
In this article, I will show feature differences between the new full-frame Nikon D600 (FX) and the older cropped sensor Nikon D7000 (DX). I have received a number of requests from our readers asking me to provide this comparison, since many photographers are considering to move to the Nikon D600 from their D7000 cameras. Please keep in mind that this Nikon D600 vs D7000 comparison is purely based on specifications. A detailed comparison with image samples and ISO comparisons is provided in the Nikon D600 Review.
With Canon having recently announced its take on budget DSLRs, the Canon 6D, the most obvious rival just happens to be the brand new Nikon D600. We’ve already seen how the latter stacks up, at least on-paper, with such great cameras as D700 and D800, but neither of those cameras were direct rivals. Priced at the same relatively low price for a full-frame sensor camera, $2099 body only, Canon 6D is as direct a rival as it can get. Lets see how it measures up against its Nikon counterpart spec-wise. Please keep in mind that this Nikon D600 vs Canon 6D comparison is purely based on specifications. A detailed comparison with image samples and ISO comparisons will be provided in the upcoming Canon 6D Review.
Since the Nikon D600 DSLR has been released this morning, I have been receiving a number of emails and comments about it from our readers. Looks like there is some confusion about the capabilities and limitations of the camera. A number of online resources are talking about the D600 and thanks to some famous bloggers, people now think that the D600 has serious problems. I am not here to defend the camera that I have not touched yet, but I would like to clarify these issues so that there is no misunderstanding or confusion.
Here is another quick specifications comparison between the new Nikon D600 and the D800 that was announced earlier in 2012. I am sure many photographers will be interested in seeing feature differences between the resolution king, the D800, and the $900 cheaper D600. Looks like both cameras are quickly becoming popular among many amateur and professional photographers, so what feature advantages does the former offer over the latter? Let’s take a look in this Nikon D600 vs D800 comparison. Please keep in mind that this comparison is purely based on specifications. A detailed comparison with image samples and ISO comparisons is provided in the Nikon D600 Review right here.
Now that the Nikon D600 is officially out, I am sure many photographers will be interested in seeing feature differences between the old and discontinued Nikon D700 and the new D600. Please keep in mind that this Nikon D600 vs D700 comparison is purely based on specifications. Note: a detailed comparison with image samples and ISO comparisons is provided in the D600 Review.
A couple of weeks ago I had an opportunity to visit Norman Koren, founder of Imatest, LLC. I have been fascinated by his software for a while now and after evaluating the software, decided to purchase it to use in our lens reviews. When I found out that his company is right here in Boulder, Colorado (where I lived for over 5 years), I gave him a call and asked if I could come over and interview him. Despite his busy and hectic schedule, he was able to accommodate me for an hour during his lunch time. Below is the text version of the interview.
When Nikon releases a new generation DSLR camera, it seems to often make little changes to the camera firmware. We typically see slight tweaks here and there, but every once in a while (especially when a new piece of technology makes it into the camera) we see some new interesting and useful features getting added into the camera firmware. In this article, I would like to point out current firmware issues that I believe Nikon needs to address, along with some recommendations (wishlist) on what Nikon should do in their future cameras. Or, perhaps Nikon might consider to implement some of the below firmware fixes/recommendations on current DSLRs – I am sure many of the Nikon owners would get excited about some of these requests.
5) Out With The Old And In With The… Old!
I find it amusing to observe that long after a technology has been declared dead, it will magically reappear after nostalgic longing causes some to reintroduce it in some form. When I first got back into photography in 2007, I came across a fellow Pittsburgher who had concocted an interesting homemade device consisting of a heavy duty cardboard tube attached to an old, beat up Kodak Duaflex TLR (twin lens reflex) camera, which was quite popular in the 50s and 60s. He attached it to one of Canon’s top DSLR and lens combos. The resulting images were grainy, heavily vignetted, filled with a variety of textures produced by the old scratched lenses, and sported a rough black border. Of course, my first thought was, “So… you bought a high end Canon DSLR and some of the best lenses in order to take pictures while focusing through a 50 year old camera bought at a yard sale for $12?” Just when we thought all those yard sale Kodak TLRs were headed for the scrap heap, thousands of photographers brought them back to life by putting them in front of some of the best DSLRs and lenses of the world. All this to take retro looking photos, which they describe as “edgy.”
The digital camera revolution, in conjunction with the explosive growth of the internet has had profound changes on photography. Some changes have been dramatic, while others have been more subtle. In times of revolutionary technological changes, it is important to adjust your perspective to the new realities and contemplate just how far we have come. I will put the second part of this article online shortly.
