HD Pentax-DA 645 28-45mm F4.5 ED AW SDM SR

A wide-angle zoom for the Pentax 645 digital system · 07-30-2014 · By PF Rumors in Pentax Rumors

Rumors of a wide-angle zoom for the Pentax 645D/645Z have surfaced: a 28-45mm F4.5 lens, which will likely be officially known as the HD Pentax-DA645 28-45mm F4.5 ED AW SDM SR, will fill the gap between the 25mm and 55mm focal lengths in Pentax's lineup of digital-era medium-format lenses.  This lens will provide a diagonal field of view of roughly 90-62 degrees.

In addition to weather-sealing and SDM autofocus, the new 28-45mm lens will feature in-lens stabilization.  It will be the second stabilized lens for the 645D system, following the 90mm F2.8 macro.

Further details, including pricing, are currently unknown.

Pentax Q2 Rumor

Successor to the Q7, styled like the original Q · 07-30-2014 · By PF Rumors in Pentax Rumors

According to the Japanese site Digicame-Info.com, Pentax will soon release a new Q-mount camera: the successor to the Pentax Q7.  This seems quite probable given the age of the Q7 (well over a year) as well as the recent discontinuation of special-order custom color kits in the US, which typically happens at the end of each camera's product cycle.

Based on the leaked product photos, it looks like the new camera's body will be styled to look more like the original Q than the Q7 or Q10.  This means that we'll likely be seeing a magnesium alloy body with faux leather, rather than a plastic body: great news for Q-system fans!

The new camera may end up being known as the Q-S1 or Q2.

Tablets for Photographers

Road Warrior Tools- can you take it all with you? · 07-24-2014 · By cjfeola in Columns

When you're a foreign correspondent, packing becomes a science. For years I lived out of a duffel that went over one shoulder and a Domke bag that went over the other. It got so that I could land in Tokyo, develop film and print while doing laundry, hand load more film canisters, replace batteries, repack and be on a plane headed out in 24 hours.

When you pack like that you become fairly particular, about size and weight and speed, and the little things that make travel work. I developed a habit of carrying every type of money in different pockets. That way when I woke up in the morning and couldn’t remember what hotel, city or even country I was in, I could head down to the lobby, follow my nose to the coffee, and keep pulling things out of my pockets until they gave me several cups.

When digital cameras replaced film, I started thinking about a digital road warrior kit: a single bag with cameras, lens, and some way to process the files and then upload them for safe keeping.

I started with laptops, and while they worked, they were always too big, too clunky and took too long to boot up for my tastes. Also, my family never seemed to believe that I would be “just a few minutes” when I dragged a laptop out on vacation…

Tablets would seem to be the perfect answer, so of course I’ve tried. Several. For the last two years I’ve carried an iPad Mini, which I’ve now replaced with the Asus T100.

I’ll start with the Asus, since most are familiar with iPads big and small. In a nutshell: the Asus T100 is the Pentax K-01 of tablets.

Pentax K-3 Prestige Edition Announced

The K-3 DSLR with a special gunmetal finish and grip · 07-23-2014 · By PF Staff in Pentax News

Pentax has just officially announced the Pentax K-3 Prestige Edition, a special version of the K-3 featuring with a gray gunmetal finish, black logo lettering, and an accompanying grip.  The Pentax K-3 Prestige also includes a special black leather neck strap (O-ST1403) in addition to the other accessories typically included with the camera.  The K-3 Prestige will come loaded with the latest firmware from the factory, but in all other ways, its specifications are identical to those of the standard K-3.  Like the black K-3, the K-3 Prestige has a magnesium alloy finish, weather sealing, and a stainless steel chassis.  

This is the second special version of the Pentax K-3, following the Pentax K-3 Premium Silver, which was launched alongside the black K-3 last November.

In the US, the Pentax K-3 Prestige retails for $1399.95 and it will start shipping in August: click here to pre-order yours at B&H.

Table of Equivalent Focal Lengths

The crop factor unmasked · 07-23-2014 · By PF Staff in Photographic Resources

Many of us have cameras with different sensor sizes; this raises the question of which lenses need to be used to get the same field of view on two different formats. Below we provide a table listing focal lengths with equivalent Field of View (FoV) across several sensor sizes.  The actual field of view (in degrees) is shown on the far right. Click the table to enlarge.

Note that the focal length of a lens (say 50 mm) is an optical property of the lens and remains the same no matter what sensor size camera the lens is mounted on.

In other words, an smc Pentax-A 50mm F1.7 lens as shown to the right is a 50 mm lens when mounted on a Pentax Q7 (1/1.7 inch sensor size), on a Pentax K-3 (APS-C sensor size), or on a Pentax film SLR (aka 24 x 36 mm or full frame). The focal length does not change with the camera. But the field of view which the lens captures does change. And so does depth of field, but that is for another article.

Some manufacturers have the bad habit of marking their lenses not with their true focal length, but with the focal length of the equivalent lens on a full frame (24 x 36 mm) camera. This is confusing. Pentax doesn't belong to that camp; they mark their lenses correctly (i.e. with the true focal length).

On Becoming A Great Photographer

Interviews with 3 Professionals · 07-21-2014 · By ccrookston in Photographic Resources

Like most amateur weekend shutterbugs, I spend a fair amount of time at websites like PentaxForums and flickr doing one of my favorite pastimes: looking at other people’s photographs.  And not surprisingly, what I see is a small percentage of pics that are true, honest, incredible works of art. They inspire me!  

But on the other hand, I also see vast oceans of photographs that are (at the risk of sounding rude) pretty much junk.

Noticing this disparity got me thinking. What is it, I wondered, that’s behind the great photographs and the great photographers?  What is the process that goes into making a truly awe-inspiring photograph? And what is the journey required to reach a level of talent where one can churn them out continually?

Not being a great photographer myself (I consider myself only slightly above average) I decided to satisfy my curiosity by finding and interviewing people who make their full time living as photographers. I wanted more than just technical info on lens, camera, aperture etc.  I wanted personal stories.  I wanted backgrounds.  After some hunting, I found three who were willing to share some of their (not so secret) secrets.

Using the Histogram to Get Better Photos

Decipher what it says, use it to your advantage · 07-18-2014 · By mattb123 in Photographic Resources

Have you ever wondered what that graph-looking thing on your camera display or in Lightroom was? Or what you are supposed to do with it? If so, then read on to find out more about the mysterious histogram and what it can do for you and your photography.

A histogram simply is graphical representation of the distribution of data. This can be applied to many things dealing with science and statistics, but in this context we will be discussing the histogram function on our cameras and the histograms generated by image editing applications like Photoshop or Lightroom.
