During the last few weeks, I have been trying to come up with a good solution for testing lenses that did not require constant movement when dealing with slightly de-centered lenses. The idea was to build a setup similar to macro rails, but one that is bigger in size and very stable at the same time. Stability is extremely important, because even a slight vibration can negatively affect lab results. Using an Arca-Swiss quick release setup was a no-brainer, because it allows moving the setup without having to deal with mounting and dismounting anything, while being rock solid when tightly secured. While my BH-55 Pro tripod head from Really Right Stuff has been serving me well for a while now, it was hard to use for minute adjustments that are often necessary when testing lenses. Therefore, I decided to replace it with a geared head that would allow very precise vertical and horizontal tilt adjustments, along with the ability to pan, when needed. My quick search revealed that unlike the army of pan/tilt heads and ballheads, which are made by a myriad of companies, there are only a few options available for geared heads today. One of them is the Manfrotto 405 Pro Geared head, which I am reviewing today.
When testing lenses, I have to make sure that my setup is calibrated and the camera is perfectly aligned with the test chart. The process can take quite a bit of time, since I have to take a picture, make minute adjustments, then take another picture and retest again. In some cases I have to repeat the process many times over, which can be very painful. To simplify and speed-up the process, I have been connecting my laptop (which sits right under the tripod) directly to the Nikon D800E with a USB cable and have been using Nikon’s Camera Control Pro to dump files into a local folder, from which I pick up and process images using Imatest software. The problem with this approach has been speed – Imatest is pretty demanding when it comes to processing large RAW files from the D800E and my laptop just could not keep up. So I ended up moving the software to my powerful desktop machine, which created another problem. Every time I take a picture and need adjustments, I have to walk back and forth between the camera setup and the computer to analyze the results and make adjustments. USB 3 cables have length limitations and even with “active” USB 3 extension cables, the maximum length is typically under 10 meters. And that’s just not going to work for me, since I often test telephoto lenses and I have to be more than 10 meters away. To address these issues, I decided to try some wireless solutions that are available on the market. The first and the cheapest product to try was the Eye-Fi Pro X2 memory card. I got a 16 GB version and wanted to see just how well the card with its software could work for my setup. In this review, I will be focusing primarily on the transfer speed of the card and its usability with the Nikon D800 / D800E DSLR.
This is a short review of the Lexar Professional 400x SDHC UHS-I Class 10 card, which I have been using for the past 6 months. I have owned 4 of these cards in 16GB capacity and decided to write a review after every single one of them failed. I have never had such problems with memory cards, especially those that have a “professional” label attached to them. So this is more of a warning to potential owners, rather than a full-blown review of a product.
About 3 weeks ago, I decided to make some changes to my tripod setup in my lens testing lab, in order to make it easier, more consistent and fluid to test lenses. My decision was based on the fact that I found myself moving the tripod a bit too much when testing lenses, especially the de-centered ones (those that do not have a straight optical axis due to a slight dislocation of one or more lens elements). I decided to replace shorter macro focusing rails for much longer and bigger rails, so that I could have more room for side to side movement and more focus bracketing options for testing telephoto lenses. As I was configuring the setup, I realized that I needed to spend close to $2K in a more versatile tripod head and lots of Arca-Swiss rails, clamps and other accessories. The first task was to replace the standard quick release plate of the heavy duty Manfrotto 405 Pro Geared Head (to be reviewed later) with an Arca-Swiss quick release clamp. As usual, I started researching for a proper solution on Google, which pointed me to Hejnar Photo Store on the first page of search, with exactly the product that I was looking for. I then spent another 30-45 minutes researching the solution and read a number of posts on different forums, where people were raving about Hejnar Photo’s products, including the adapter that I needed. This was very important for me, because I needed a setup that would be extremely reliable and stable, especially for handling heavy super telephoto lenses.
In this video, I decided to cover a couple of important aspects of using the sensor gel stick. First, I wanted to show what the product looks like when shipped and what it comes with, then answer some of the most frequently asked questions by our readers (see below for the text version), before actually showing how to use the product on a camera sensor.
I have shot this video a couple of weeks ago and have not had a chance to post it due to my crazy schedule. Basically, it is some detailed information and history about the Sensor Gel Stick and how it works when compared to other sensor cleaning solutions. Since our readers have been wondering about the tool and asking questions about it, I thought it would be a good idea to share it. This is the first part of the video, where I talk about the stick. The second part on how to actually use it will be posted tomorrow, with some detailed instructions for reference.
Maybe you can teach an old dog new tricks. I hate camera straps, they seem to always be in the way and so more often than not, I end up ditching them. Instead, I end up carrying the camera by the body or by the tripod foot when using larger lenses. I should say, I used to hate straps, until I finally used a BlackRapid Sport and in this quick review we will discuss the advantages of this strap.
I thought I was perfectly happy using the standard hard plastic Nikon screen protector that came with my D800. It does what it’s supposed to do, right? It protects the screen from getting scratched without getting in the way of actually seeing the screen. Why mess with a good thing? That’s what I thought until I was given the opportunity to try out an Expert Shield Screen Protector.
Earlier this week, when I wrote about my experience at the 2013 Photo Plus Show, I pointed out that I found a product that I have been searching for the past 4 years. It was something that I found on the last day at the conference, while going through the smaller, less popular booths towards the end of the exhibit hall. I first hesitated about what I saw, but as soon as I realized that it was exactly what I had been looking for, I got very excited and bought one for myself immediately (and pretty much forced Tom to buy one as well). You might be wondering what it was – well, as weird as it may sound, it was a Sensor Gel Stick!
We’ve all seen the high speed photography shots of bullets piercing objects, water droplets or lightning strikes but maybe aside from lightning strikes, not all of us have had the opportunity to take photos like that. Many of us only get to admire other photographer’s work when it comes to ultra fast action shots like these. I recently got a chance to play with a multifunctional trigger that makes high speed photography easier and fun but also does more than just help with high speed photography. In this review of the Nero Trigger, we will look at some of its modes and how it performs.
UPDATE: Nero Trigger is now MIOPS!
