Pentax 645Z Announcement

Earlier this week, Ricoh Imaging introduced the Pentax 645Z, a high resolution 51.4 MP medium format DSLR camera. While Nikon has been relatively quiet on the resolution front with its now 2+ years old 36 MP D800/D800E models and Canon has not stepped up above 24 MP, Pentax is stepping in with a larger sensor that provides super high resolution 51.4 MP images. With its 43.8 x 32.8mm size sensor, the 645Z has a smaller version of the medium format (MF) sensor that is similar in size to the Leica S-System, although with a different aspect ratio of 4:3 vs 3:2. Compared to full-frame sensors, the physical size of the 645Z MF sensor is about 166% (or 1.66 times) larger, which is a huge difference. Enough of a difference to allow for relatively large pixel size of 5.3 microns – bigger than 4.8 microns on the Nikon D800/D800E. Why does this matter, you might ask? Well, that’s because the Pentax 645Z comes with a CMOS sensor, which is similar technology as we see on all modern DSLR cameras. Compared to traditional CCD sensors used on medium format cameras, a CMOS sensor is capable of yielding images with very little noise at high ISO sensitivity levels. As a result, the Pentax 645Z has an ISO sensitivity range of 100 to 204,800, which is a mind-boggling number for a medium format camera.

Thoughts on the Sigma 50mm f/1.4 Art

Sigma announced the new Sigma 50mm f/1.4 Art lens back in January of this year, but we were left with a couple of big unknowns such as the price. I guess it has become the latest trend to announce early development efforts by a number of manufacturers now – Nikon did the same with their Nikkor 800mm f/5.6 lens and the D4s DSLR camera. A couple of days ago, Sigma finally announced the pricing and availability of the Sigma 50mm f/1.4 DG HSM “Art” and I must say, after hearing rumors about Sigma challenging the Zeiss Otus 55mm f/1.4 in optical quality, I was very surprised to find out that the lens is going to be retailed for $950. As you may already know, I am a big fan of the new revamped line of Sigma lenses. After reviewing the 35mm f/1.4 Art, I was blown away by its sharpness, focus speed / accuracy and color rendition. So when Sigma announced the 50mm f/1.4 Art series, I looked at the MTF charts and knew immediately that the lens will not disappoint.

Fuji X-T1 Preview and Image Samples

I have been shooting with the Fuji X-T1 for the past several weeks and I must say, I am just blown away by what this little camera can do. While I will be working my way to a review fairly soon, I wanted to provide a quick summary of my thoughts so far on the X-T1, along with some sample images using the 35mm f/1.4 and 56mm f/1.2 lenses. Ever since I received the X-T1, I just cannot stop myself from taking it every time when I go outside. Pretty much everything about the camera feels right to me – from the amazing controls and dials on the top, to the fast and responsive autofocus and the huge electronic viewfinder (EVF), making the camera a pure joy to use.

Profoto 3′ RFi Octa Softbox Review

While testing out the Profoto B1 500 flash head, I also had a chance to use one of my favorite light modifiers, a 3 foot octabox (also known as “octa softbox”, “octabank” or just “octa”), known as “3′ RFi Octa Softbox” by Profoto. Although Profoto carries a wide array of light modifiers and accessories in its arsenal of lighting equipment, I specifically wanted to get a smaller octa for outdoors photography. The primary reason was portability without compromising too much on the size. As you may already know, the larger the source of light in flash photography, the softer it is on the subject. The 5 and 7 foot octas were just too big and the smaller rectangular softboxes were too small for my taste. Quality-wise, both octaboxes and softboxes produce equally good quality light – the only difference is catchlight. I prefer to have more round catchlight in my subject’s eyes, rather than a square, so I prefer using octaboxes, umbrellas, parabolic softboxes and beauty dishes for that reason.

Profoto B1 500 AirTTL Review

When Profoto announced their first truly portable setup with the Profoto B1 500 AirTTL battery powered flash last year, the news immediately caught my attention and I requested to get a sample unit for a review. The reason was fairly simple for me – I got tired of lugging around a huge and heavy battery pack for my Elinchrom Ranger lights when working on remote jobs. Speedlights are great for indoors and low-light environments, but they just do not have the juice to run big light modifiers or overpower the sun in mid-day lighting conditions (unless you use packs of them like Joe McNally does). For these reasons, I have been using big lights for sometime now, but with the huge inconvenience of carrying a heavy portable battery. Although the Profoto B1 lights have less power in comparison with a total of 500 watts, I realized that I rarely go full power with my Elinchrom Rangers anyway, so the B1 was plenty for most of my work. The biggest advantage that I saw in the Profoto B1 was portability – no need for any external power sources! Just attach a battery on the side of the head and you are ready to go. And with a built-in slave trigger, the head can be controlled with a radio or infrared remote units wirelessly.

Case Study: Shooting NYC Skyline

A good friend of mine, Yechiel Orgel, who is a professional commercial photographer specializing in product photography out of NYC, contacted me last week and asked for some advice on shooting the New York City Skyline from a rooftop of a luxury condo building in Brooklyn. The aim of the shoot was to show the NYC skyline that can be seen from the roof of this building. The building is located in downtown Brooklyn, roughly 3 avenue blocks from the water. The client apparently wanted to get a really large print, which would be displayed in the lobby of the building, possibly made into a wallpaper. Yechiel was a little uncomfortable with these requirements, because it is not his area of expertise and he has never produced prints that large. So he wanted to get some recommendations on how to best handle the situation. He presented a list of the following requirements:

  1. The image needs to show the surrounding area, along with the NYC skyline in the background
  2. The NYC skyline needs to be clearly visible, with the least amount of haze
  3. Resolution and detail level need to be high, because the planned print size is 9′ long
  4. Access to the rooftop is mostly limited to business hours, with some freedom after hours

Here is the view from the rooftop that had to be captured:

What is Ghosting and Flare?

When light rays coming from a bright source(s) of light (such as the sun or artificial light) directly reach the front element of a camera lens, they can reflect and bounce off different lens elements, diaphragm and even off the sensor, potentially degrading image quality and creating unwanted objects in images. Better known as lens “flare”, the effect can impact images in a number of ways: it can drastically reduce image contrast by introducing haze in different colors, it can add circular or semi-circular halos or “ghosts” and even odd-shaped semi-transparent objects of various color intensities. Flare is not always undesirable in photography though – sometimes in is used creatively to add artistic elements to images. In fact, lens flare is often deliberately added to movies and computer games to add a sense of realism and boost the visual experience of the viewer.

Dune Sunset Panorama

To help decide whether to use flare in images, it is a good idea to understand why it happens in the first place. Let’s go over the causes of flare in detail, then discuss ways to use, reduce or perhaps completely avoid it.

1) What is Lens Flare?

Lens flare occurs when a point of light source such as the sun is much brighter than the rest of the scene, and it either happens to be in the image (within lens angle of view), or simply hits the front element of a lens without being present in the image. Depending on the position of this bright light source, it can result in a lot of haze / lack of contrast, orbs and polygon artifacts scattered throughout the image, semi-round shapes with rainbow colors, or a combination of all of the above. This happens due to internal reflections that take place inside the lens and even between the imaging sensor and the lens (more on that below). Take a look at the below illustration:

Trade-in ANY camera for $300 towards a Sony A7/A7R

What happens when a manufacturer desperately wants rapid market share gain and mass adoption of its full-frame mirrorless cameras? You get a hard-to-refuse offer that instantly gives you cash for ANY camera in ANY condition. That’s right, Sony is giving away $300 if you trade-in your old camera. And when I say old, it could be a broken/non functional film camera that is not worth a penny, or a dead point and shoot that you have had in your drawer for years and never had a chance to dump it. With the already aggressively priced Sony A7 and A7R cameras, giving access to a full-frame A7 camera body at $1700, this $300 credit makes the A7 the cheapest full-frame camera we have seen to date, at under $1500 price tag. Clearly, Sony is not looking into making money from this rebate program and just wants rapid adoption of its brand new technology. When I originally shared my thoughts about the potential impact of the Sony full-frame mirrorless system on Nikon and Canon sales, a number of our readers criticized me for what I wrote and argued that there was no threat for the big two. Well, judging by what I hear so far in terms of sales and adoption, even among our readers, Sony is doing really well. And seeing how the Nikon D610 got a $100 off just after a month of its launch tells me that Nikon is definitely adjusting its pricing in response and Canon is pretty much doing the same with its 6D line. As Sony continues to expand its market share, I am sure we will be seeing price drops across the industry from all manufacturers. This is definitely good for us photographers, since healthy competition is always a good thing that drives innovation and decreases prices. With mirrorless having less components and bulk than a DSLR, it will be an interesting battle to watch for the next few years.

Nikon and Canon lens rebates expiring in a couple of days

Just wanted to post a quick reminder that the Nikon and Canon Lens and Speedlight rebates will be expiring in just two days and will not come back, probably till the holiday season at the end of the year. Nikon has already extended its rebate program until the end of March and with the end of the tax season, it will also end the rebates. As you may already know, there are two types of rebates taking place right now – lens-only rebates and camera combo rebates. I won’t go over these rebates in detail and provide my recommendations, because I have already done that in the previous article.

Nikon Lens Rebates

If you are a Canon shooter, you can still take advantage of the killer promotions for the Canon 24-70mm f/2.8L II USM and Canon 70-200mm f/2.8L IS II USM, both of which get double promotions. Basically, the 24-70mm f/2.8L gets an instant $300 rebate and you can shave another $200 off the price with a mail-in rebate, bringing it down to $1799 (total $500 off). The 70-200mm f/2.8L IS II gets a $140 instantly off and you will also get a $200 mail-in rebate, so you pay $2159 for it.

How to Photograph the Milky Way

Many travel and landscape photographers, including myself, try to avoid shooting scenery with a clear blue sky. As much as we like seeing puffy or stormy clouds to spice up our photographs, we have no control over what the nature provides each day. Sometimes we get lucky and capture beautiful sunrises and sunsets with blood red skies, and other times we are stuck with a clear, boring sky. When I find myself in such a situation and I know that the next morning will be clear, I sometimes explore opportunities to photograph the stars and the Milky Way at night. I am sure you have been in situations where you got out at night in a remote location and saw an incredibly beautiful night sky with millions of stars shining right at you, with patches of stars in a “cloudy” formation that are a part of the Milky Way. If you do not know how to photograph the night sky and the Milky Way, this guide might help you in understanding the basics.
