Sigma 120-300mm f/2.8 DG OS HSM Review

Sigma 120-300mm f/2.8 DG OS HSM

This is an in-depth review of the Sigma 120-300mm f/2.8 DG OS HSM Sport, a high-end super telephoto lens with a versatile zoom range and a wide constant aperture of f/2.8, designed for wildlife, sports and portrait photographers. This is the third iteration of the lens. Its predecessor, the Sigma 120-300mm f/2.8 EX DG OS APO HSM was released back in 2005 with identical optical design. What has changed, is the exterior make and appearance of the lens (along with the tripod collar and tripod foot), the new rigorous quality control that Sigma has implemented on its new lines of high quality lenses, and the ability to attach a USB dock for fine tuning the autofocus operation of the lens. In this review, I will go over the technical specifications of the lens, talk about its optical features and performance with and without teleconverters, and compare it to other super telephoto lenses like Nikon 200-400mm f/4G VR and Nikon 300mm f/2.8G VR II.

Nikon 800mm f/5.6E VR Review

Nikon 800mm f/5.6E FL ED VR

This is an in-depth review of the Nikon 800mm f/5.6E FL ED VR, an exotic super telephoto lens designed for wildlife and sports photographers. Nikon first teased us with its plans to release an 800mm lens in July of 2012, with an official announcement that followed in January of 2013 (along with the Nikon 18-35mm f/3.5-4.5G ED lens). Nikon has not updated its manual focus 800mm f/5.6 ED-IF lens for over 25 years, so it was about time to introduce an autofocus version of the lens to the market. The Nikon 800mm f/5.6 VR is a significant milestone for the Nikkor line, because this is the first lens to have the letters “FL” on the lens name, which indicate that fluorite elements are used in its optical design. Although Canon has been using fluorite elements in its exotic super telephoto lenses for a while now, Nikon historically has only used fluorite elements in its medical / microscope lenses. So in a way, this is the first lens of its kind for Nikon.

Nikon 300mm f/4D AF-S Review

Nikon 300mm f/4 AF-S

The original review of the Nikon 300mm f/4D AF-S lens was published back in 2009 and was very short. I decided to completely rewrite it, with all the latest information, MTF data, more feedback and sample images, so you are looking at an updated version. If you are a birder, you have only two budget choices for Nikon – either the Nikon 300mm f/4D IF-ED AF-S or the much more expensive Nikon 80-400mm VR that was introduced in 2013. All other semi-professional lenses by Nikon are not good enough/long enough for birding. The old 80-400mm f/4.5-5.6D VR was too slow to focus and a lot of people including myself expressed their frustration with it for fast moving birds. I have been using the Nikon 300mm f/4D lens for over 6 years now and have been very pleased with the results. I take it with me everywhere I go and have used it more than any other telephoto lens so far. It is relatively light and I primarily use it handheld for shooting birds and other wildlife of Colorado.

Nikon 80-400mm VR Review

Nikon 80-400mm f/4.5-5.6G ED VR

On March 5 of 2013, Nikon released the AF-S NIKKOR 80-400mm f/4.5-5.6G VR, the long awaited update to the 80-400mm f/4.5-5.6D VR that was released over 13 years ago as Nikon’s first lens to sport image stabilization (Vibration Reduction) technology. I have been impatiently waiting for this lens update for quite some time now for a number of reasons. First, it is the only Nikon budget lens that can reach 400mm focal length without teleconverters. Second, it is a very versatile lens with a huge zoom range, which can be quite useful for outdoor sports and wildlife photography. Third, it is a relatively lightweight lens one could hand-hold for extended periods of time, especially when compared to any of the Nikon super telephoto lenses. And lastly, the old Nikon 80-400mm VR had a very slow autofocus motor and it was almost unusable for anything that moves, making the Nikon 300mm f/4D pretty much the only “budget” telephoto choice. So this much-needed, long overdue update was certainly welcomed by many of us Nikon shooters.

Canon vs Nikon Telephoto Lenses

Ratio of Focal Length to Weight

One of our readers, Simon Speich sent me an interesting article that compares Canon and Nikon Telephoto lenses. He created a couple of fun charts that take into account lens weight, maximum aperture and focal length and he came up with a graph that shows which manufacturer offers the best focal length to weight ratio. Give it a read, I thought this was great to share with our readers!

Site Performance and Other Updates

Burrowing Owl - Nikon 80-400mm + 1.4x TC

Some of our readers are probably wondering what our team has been up to lately, so I wanted to give a quick update on our activities. I apologize for not being able to post articles lately – I have been extremely busy with a number of projects, so I asked Lola to fill in for me. I have been working hard on expanding the lens database (which has been enhanced with even more useful information) for the past few months and this past week I was able to migrate our previous comments system to “Disqus” – a robust commenting system used by some of the most popular websites on the Internet. If you have tried commenting on some of the reviews with over a few hundred comments lately, you probably noticed how slow those pages respond, sometimes taking up to several minutes to load. All those subscription options and other comment features we implemented in the past took their toll on load speeds, so I pretty much was forced to migrate to a better commenting system. I am sure most of you will appreciate this change, but I do want to let you know that there are some drawbacks to the new system. There was no way for me to migrate previous post subscriptions, so if you used to receive updates whenever someone posted a comment in a particular article, you will have to re-subscribe to those posts via Disqus (please note that your general subscription to receive email notifications when we post articles is unaffected, this is only for comment subscriptions). Aside from this, you will love the new commenting system. And for those that hate Facebook and other social media, there is no need to register for an account at any of those sites, so you can still post as a “guest”. In addition, many of our readers reported site performance issues, so I was also able to migrate most of our content to better and faster hosting. The pages and images should now load extremely quickly in comparison. On top of that, I have been evaluating options for more social interaction between our readers via forum and other means (no, we will not be integrating our site with Facebook or Twitter, this will be completely separate). But this is not something I want to roll out immediately – integration and testing will take some time to complete. I am hoping to do this sometime before the end of the year.

Wildlife Photography Tips: Use a Bean Bag

Bean Bag for Photography

It’s been a while since we had a tip for beginners, so here is a quick post for the wildlife photographer. It’s not uncommon for friends of mine to see a photo like the one below and for them to ask where I took it. Quite frequently my response to them is, “From the window of my car.” They usually laugh thinking that I am joking and then I tell them that I’m serious. If you take many wildlife shots, you will quickly realize that oftentimes animals are acclimated to cars and if we stay inside them, we don’t stress them as much and they don’t flee as fast.

DX or FX for Sports and Wildlife Photography

Dolphin Jump

It seems like the debate of DX vs FX for wildlife and sports photography is a never ending one. DX shooters argue that they get more reach, stating that DX is like a “built-in 1.5x teleconverter”, or that DX setups are lighter due to smaller lenses and less expensive, or that DX chops off the corners of lenses, thus reducing vignetting and other optical issues. On the opposite side of the fence, FX shooters argue that they get better image quality at pixel level, better viewfinder, less diffraction issues, better AF performance in low-light, etc. Seems like we have two camps, each defending their own side for various reasons. Having spent a number of years shooting both DX and FX starting from the first generation Nikon FX cameras and every single DX camera manufactured by Nikon to date, and having talked to a number of other photographers that shoot for a living, I came to a conclusion that there are some myths surrounding the DX format that need to be debunked. In this article, I will provide my personal insight to this topic and explain why I believe that FX is always better for photographing sports and wildlife. This article evolved as a result of recent discussions of the subject with some of our readers.

Image Degradation with Nikon Teleconverters

AF-S Teleconverter TC-20E III

A fellow photographer recently asked me how much image degradation one would see with each Nikon teleconverter. As a nature photographer, I have been wondering myself about this for a while, but never had a chance to actually quantify what the image degradation figures would look like when using the TC-14E II, TC-17E II and the TC-20E III with Nikon lenses. I have been relying on field use and my vision so far and here is what I have thought about each teleconverter.

Nikon 80-400mm f/4.5-5.6G ED VR Announcement

Nikon 80-400mm f/4.5-5.6G ED VR

In a rather surprising announcement today, Nikon released a major update to the existing 12 year old Nikkor 80-400mm AF-D lens. The new Nikon AF-S NIKKOR 80-400mm f/4.5-5.6G ED VR has a completely redesigned internal focus optical formula with Nano Coating, Super Integrated Coating and extra-low dispersion glass elements. On top of that, the lens sports a second-generation Vibration Reduction (VR II) system for up to 4 stops of shutter speed compensation and a silent wave motor (SWM / AF-S), which means that autofocus will function on any modern Nikon DSLRs, including entry-level models like D3200. This is one of the few Nikkor lenses to have “Super ED Glass”, which has a lower refractive index and light dispersion than ED glass, making the new 80-400mm a premium lens for both enthusiasts and professionals. And with a versatile focal length of 80-400mm, the lens is well-suited for sports and nature photography.
