There have been some interesting discussions about the pros and cons of various sensor sizes and how they impact angle of view, lens focal length and the depth-of-field that results. For example, some photographers bemoan the fact that it is difficult to achieve a shallow depth of field at a particular equivalent-field-of-view with a CX sensor using 1 Nikon lenses, while others find it useful to be able to get deeper depth-of-field at more open aperture settings such as f/1.8 and f/2. Some D800 shooters are concerned about diffraction setting in above f/8 when trying to achieve deep depth-of-field with a high pixel density 36mp FX sensor, as are many photographers who use high pixel density sensor DX bodies.
Having been testing lenses extensively for the past few years, I have seen all kinds of optical defects on even the most expensive / exotic lenses that cost thousands of dollars. One of the most common issues I have seen so far is lens de-centering, where a single optical element or a group of elements are not properly aligned with others, resulting in uneven performance across the frame. Some lenses have very slight de-centering, which only software like Imatest can reveal, while others have very noticeable de-centering (particularly lower-end zoom lenses), where a portion of the frame would always appear less sharp in images. Then there are other optical issues that also impact the overall contrast and sharpness of lens. And testing lenses with all kinds of optical issues can often be a challenging task.
I have just added another section to the Camera Comparisons page of the Olympus OM-D E-M1 review, where I provided RAW performance comparisons between the OM-D E-M1 and the Fuji X-T1. Some of our readers requested this comparison, so here it is for those that just want to see this particular section of the review. Although the X-T1 has a similar resolution of 16.3 MP, it is physically larger in size (APS-C vs Micro Four Thirds) and hence has larger pixels than the OM-D E-M1. Let’s take a look at ISO 200 (Left: Olympus OM-D E-M1, Right: Fuji X-T1):
Grimsby Ontario is on the raptor migration route and every year the town holds an indoor “RaptorFest” event at the local hockey arena during which various presentations of live birds, and educational initiatives are conducted. A fast, mid-range telephoto like the Nikkor 200mm f/2G VR would be the perfect lens to photograph birds during this indoor event. Like most people, I don’t have the $6,000 or so it would take to own the 200mm Nikkor…but I thought I might have a reasonable solution in my camera bag.
This is an in-depth review of the Olympus OM-D E-M1 mirrorless camera that was released on September 10, 2013. Standing above all other Olympus mirrorless cameras, the E-M1 is a flagship model with the most impressive list of features. Built on the success of the Olympus OM-D E-M5 (which we highly praised), the E-M1 reigns over the OM-D line on a number of features – from the design of the camera and its incredibly fast autofocus system to the advanced shutter mechanism, high-end electronic viewfinder, WiFi and amazing weather sealing options. In fact, the E-M1 is one of the very few freezeproof, splashproof and dustproof interchangeable lens cameras on the market today.
Recently when I was investigating ultra-lightweight and portable tripods I came across the Tamrac ZipShot. This tripod is one of the most innovative, lightweight tripod designs to hit the market in some time. The tripod comes in two sizes: the TR404 mini which extends to 28” in height, weighs 9 ounces and folds up to 9” in length. The larger model is the TR406 which extends to about 44” in height, weighs 11 ounces, and folds up to 15”. Both models are weight-rated by Tamrac to support 3 pounds.
This is a review of Weye Feye product (usage with Nikon D800 camera, iPhone 5 & iPad 2). Weye Feye is a wireless and remote control unit for a DSLR. This product is made by a company called “XSories”. I think this is a French company with a subsidiary located in Hong-Kong. Another device providing similar functionality (and known better than Weye Feye) is CamRanger. The primary reason why I started looking at an external camera control unit was pretty simple. Prior to purchasing and using the D800, I was using Olympus E-5 cameras (still use them). Olympus E-5 has a fully articulating LCD screen. Having this fully articulating screen was and is very convenient, as I often take shots with strange angles, especially low to the ground. Most of the semi-pro DSLRs (just about all brands) do NOT have articulating screens. The absence of this functionality on semi-pro and pro cameras actually infuriates me, because it significantly limits the artistic ability of the photographer. Why do I have to get down either on all fours or my stomach or in a crouching tiger position in order to get the shot I need? Please, put articulating screens on these cameras! So when I got my D800, I was searching for a long time for a device that could “replicate” the articulating screen of my E-5s. There are many various add-ons available, but all add significant bulk to the camera, require separate batteries and seem very cumbersome. Most of my photography is done in an external, non-studio environments, so I try to limit the bulk of my equipment.
The subject of using or not using protective lenses can invoke heated debates among photographers, with both sides often fiercely defending their choices. I am not going to debate whether it is right or wrong to use protective filters – that’s certainly a personal choice. I have been using them for a number of years now to protect my higher-end lenses and make it easier to clean lenses with recessed front elements (such as on Nikon 50mm f/1.4G / f/1.8G). Having had bad experience with purchasing a low-quality no-name brand filter when I just started photography (it was sold to me as a “must-have” at a local photo store), I learned what such a filter can do to my photos the hard way. Since then, I have only been purchasing multi-coated B+W filters that use high-quality Schott glass. I have been very happy with these filters and have been telling our readers to either use the best they can find, or not use filters at all.
One of the frequently asked questions by our readers when we post information on Zeiss lenses (which are often optically stellar), is why Zeiss does not make autofocus lenses for DSLR cameras from Nikon and Canon. As you may already known, Zeiss is currently making autofocus lenses only for two specific mounts – Sony E (for NEX / Alpha series mirrorless cameras) and Fuji X. This line of autofocus lenses labeled as “Touit” is limited to a few lenses at the moment, with full autofocus capability and compatibility with both Sony and Fuji mirrorless cameras. So one might naturally ask why Zeiss has finally started making autofocus lenses and wonder if it has plans to start developing autofocus lenses for Nikon and Canon mounts. Although I have known the reason behind this for a while now, I decided to ask the question again from the Zeiss team at the Photo Plus show in NY last year. Specifically, I wanted to find out if Zeiss is planning to change their strategy in the future in regards to DSLR lenses.
This article is written in response to “The Question of 18-300mm Lenses” article written by Romanas Naryškin. I used to like my 18-300mm zoom – I called it my Guilty Pleasure Lens (GPL). It was hands-down the most fun lens I ever shot with. When I wanted to just go out on an adventure outside and had no idea what I’d run into, instead of grabbing my FX body, my 16-35mm zoom, 50mm prime, 105mm macro, 80-400mm zoom and of course a manservant to carry all that gear, I’d grab GPL and my D7000 and blast on down the trail. Sure GPL wasn’t the sharpest knife in the drawer, but neither am I. In our shared ignorance we’d shoot grand vistas or cool nature abstracts or maybe even crawl through the dirt for a close-up or two. What a fool I was thinking I’d found a partner that liked to do all the things I liked to do.
