Nikon has just announced the Nikon D610 camera, an update to the popular entry-level full-frame DSLR. It has been a little over a year since the Nikon D600 came out. Considering the typical refresh cycle of 2-3 years for lower-end camera bodies, this is a pretty unusual update that is meant to address the dust issue that we previously discussed in our Nikon D600 review. After a number of complaints from major review sites, including DPReview, Nikon finally acknowledged the flaw and issued a service advisory. To keep the image of the D600 line good, Nikon decided to release a refresh sporting mostly identical features. And to sweeten up the deal, Nikon made a few tweaks to the camera, making it even more attractive. But the biggest surprise is the price of the new D610 – it is now $100 cheaper than what the D600 was when initially launched, at $1999!
We’ve known that Zeiss was working on a special lens for a while now and finally the super-prime Distagon 55mm f/1.4 has been officially announced. Looking at the two basic parameters – focal length and aperture – there isn’t really anything all that special about it, just another normal prime with slightly more reach than usual. Yet there are several hints that point out neither focal length nor aperture tell the whole story. This lens is big, heavy and complex. It is also manual focus only. But the most shocking aspect is the price of $4000.
Today, Pentax has released the replacement for its popular and highly-regarded K-5 (II) models. Being one of those manufacturers who know how to offer plenty of bang for your buck, the new Pentax K-3 offers a lot of improvements over the older model. This time, though, the headline feature is not a new sensor or improved AF system, but the AA filter that you can adjust on the go for more resolution or less moiré.
1) Overview and Specifications
At the heart of the camera there is a new 24 megapixel sensor. From what I can tell, it is not the exact same unit found in Nikon D7100 (click here to read our review), but I can’t be completely sure. It is very similar, though. Why am I mentioning Nikon? Not only because it is a direct rival to the K-3, but predecessors of both new DSLR cameras also shared the same 16 megapixel Sony sensor with small tweaking differences, perhaps. In any case, if previous Pentax cameras are of any indication, the new sensor should perform admirably and on par with competition, certainly very similar to D7100′s sensor. There is also a new 27-point phase-detect autofocus system – certainly a much-needed update which should work in light as low as an impressive -3EV.
Vignetting, also known as “light fall-off” (sometimes spelled “light falloff”) is common in optics and photography, which in simple terms means darkening of image corners when compared to the center. Vignetting is either caused by optics, or is purposefully added in post-processing in order to draw the viewer’s eye away from the distractions in the corner, towards the center of the image. Depending on the type and cause of vignetting, it can be gradual or abrupt. There are a number of causes of optical vignetting – it can naturally occur in all lenses, or can be caused or increased/intensified due to use of external tools such as filters, filter holders and lens hoods. In this article, I will talk about each type of vignetting and also discuss ways to reduce or increase the amount of vignetting in photographs using post-processing software like Lightroom and Photoshop.
1) Types of Vignetting
As I have already pointed out in the introduction of this article, there are different types of vignetting that one might encounter when taking pictures or viewing images. Some types of vignetting are naturally caused by the optical design of lenses, others can occur when using third party accessories such as filters and extended hoods and some are artificially added by the photographer in post-production. Let’s take a look at each type in detail.
1.1) Optical Vignetting
Optical vignetting naturally occurs in all lenses. Depending on the optical design and construction of the lens, it can be quite strong on some lenses, while being barely noticeable on others. Still, vignetting occurs on most modern lenses, especially on prime / fixed lenses with very large apertures. There are two causes for this. First, at the widest apertures, the light than enters the lens is partially blocked by the lens barrel, as indicated by the below diagram:
A quick reminder for those who haven’t had the chance to take advantage of Nikon’s great camera + lens rebates. The program is about to end (deadline is September 28th), so if you were planning on purchasing a Nikon body and a lens (or several), there is no better time to do just that.
Our readers frequently ask us about the performance of classic Nikkor lenses, some of which were kept from the film days, some inherited and others acquired at an auction or a garage sale. Considering the high cost of modern Nikkor lenses, older lenses can be of great value, especially AF-D and Ai-S manual focus models that could be snatched for 3-4 times less than their modern counterparts. Unfortunately, due to the fact that I never owned those older classics or had any access to them, I have never been able to test and review them. While building our lens database, I realized that it was very difficult to obtain information on older lenses and almost impossible to find product images. So I decided to look at local product listings and auction sites like eBay to find old lenses of good value. Not the hard to find / rare items, but the ones that are commonly found everywhere. Thanks to the gracious support of our readers, I was able to find a few good deals and use some of the money to fund this project.
This is an in-depth review of the Fujifilm X-E1 mirrorless interchangeable-lens camera, which was released on September 6, 2012 right before the Photokina event in Cologne, Germany. After the success of the X100 line and the release of the X-Pro1 (which initially received a rather mixed review from us due to its poor AF performance), Fuji introduced the X-E1 – basically a lower-end version of the X-Pro1. It was not an unexpected move, given how quickly Fuji was growing in popularity, thanks to its amazing retro design and excellent image quality. Despite its autofocus flaws and other quirks, both the X100 and the X-Pro1 created a huge fan base and a healthy community of supporters. The X-Pro1 was an expensive camera aimed at professionals and enthusiasts, so the X-E1 was naturally targeted as a more budget version with less features. In this Fuji X-E1 review (based on Firmware 2.00), I will provide detailed information about the camera, along with some image samples, and compare it to other cameras from Nikon, Canon and Olympus.
Nikon has just made a very surprising move and released a rugged Nikon 1 mirrorless camera, the AW1. I have not been excited by a Nikon announcement in a long time now as they have, just like Canon and Sony, been releasing products that have barely changed since their last iteration. Not this time. The Nikon 1 AW1 is the first camera in its niche, and I hope it is not going to be the last. Of course, a waterproof interchangeable lens camera makes little sense without appropriately rugged lenses. Therefore, two lenses – a 10mm f/2.8 AW and a 11-27.5mm f/3.5-5.6 AW – have also been announced. A proper new addition, this, and will make Nikon 1 system very tempting for some.
Fujifilm has recently announced a new addition to its X-series of interchangeable lens compact camera system. Fujifilm X-A1 positions itself right below the previous entry-level model in the range, X-M1. At the same time, it is a camera many Fujifilm fans will likely not appreciate all that much. A lot of the initial skepticism may be due to the fact it is not very different from the recently announced X-M1. But more importantly, a difference these two cameras have is also a major one. Because Fujifilm X-A1 has a traditional Bayer color filter array rather than the rightly praised X-Trans. A recipe for failure? Not quite. Before we dive into an overview, though, let’s take a quick look at the specs.
This is an in-depth review of the Fuji X-Pro1, a highly anticipated mirrorless interchangeable-lens camera. Built on the success of the Fuji X100 and aimed at pros and photo enthusiasts that need a lightweight camera alternative to a DSLR with amazing image quality, the Fuji X-Pro1 is the first mirrorless interchangeable-lens camera from Fuji. Along with the X-Pro1, Fuji simultaneously introduced three prime lenses – Fujinon 18mm f/2.0 XF R, Fujinon 35mm f/1.4 XF R and Fujinon 60mm f/2.4 XF Macro, all specifically designed to be used for the new Fuji X mount. In this Fuji X-Pro1 review, I will not only provide detailed information about the camera, but will also try to answer the many questions that we have gotten so far on the camera from our readers, along with comparisons to Nikon and Canon DSLRs.
I had an opportunity to work closely with the Fuji X-Pro1 on two separate occasions – once when the camera initially came out back in 2012 and again in the summer of 2013, after the latest 3.01 firmware update was released. I had a number of complaints about the X-Pro1 in my original review, because the camera was full of bugs and autofocus problems. The latest firmware 3.01 addressed many of those concerns, so I am simply revisiting the same review and re-evaluating the camera based on my latest findings.
