A Bit of A7R Sanity: Rising Above the Trash Talk and Fanboy-ism with Actual Facts

A while back I wrote a post I humbly called Roger’s Law of New Product Introduction, complete with the graph shown below. The release of the Sony A7R has demonstrated the accuracy of that post as few other releases have. Read more…

Sony a7R: A Rising Tide Lifts All the Boats?

a7r_2

I have to admit I didn’t get too worked up when the Sony A7 and A7R were released. The last time I wrote about Sony it was how there were so few lenses for the NEX system years after introduction. So now we’re going to a system requiring a whole new lens mount. Sure the camera’s specs were interesting. But the idea of yet another camera body good mostly for shooting lenses on adapters wasn’t very exciting. So I planned to ignore it.

But my friends over at Imaging-Resource/SLRGear were waxing poetic when they talked about their testing of the A7. Then they started claiming that the lenses were really good, too, and sent me some rather shocking test results. Plus, I will admit when it arrived I kind of liked the look and feel of the camera. It’s a very small camera for a full-frame, but with a nice deep grip that felt good in my overly large hands. Sort of a retro appearance. So even though we were a bit backed up, Aaron and I decided to at least run some preliminary testing in our Imatest lab with the A7R. Read more…

Metabones Works Some More Magic With Its New Speedboosters for Blackmagic

blackmagic5

Metabones, maker of the impressive Speedbooster adapters is back at it again. When the Speedbooster first came out, I wrote about it being like magic, increasing the aperture and field-of-view of Nikon and Canon full-frame lenses mounted to NEX and micro 4/3 cameras, while maintaining or even improving image quality. Now they’ve brought the Metabones magic to the Blackmagic cinema and pocket cinema cameras. Read more…

The Devil’s Photography Dictionary

Picture — A representation in two dimensions of something wearisome in three. – Ambrose Bierce

I’m a fan of the satirical and cynical definitions of Ambrose Bierce, first written as a daily newspaper column and later collected in The Devil’s Dictionary. (It was originally called the Cynic’s Word Book, but so many politicians of the day called Bierce a Devil that he felt the new title more appropriate). Read more…

Inspecting an ‘In Spec’ Lens

lensrentals8

I’m going to open a can of worms today. I’ve been getting more and more emails from people telling me the same story that goes like this:

I’ve got this lens. It’s awful. I’ve sent it in for adjustment and the service center tells me it’s ‘in spec’ and nothing is wrong with it. Am I crazy?

Nikon’s D610 Gets a Dust-Free Green Light

D610_front.high

Way back when, I wrote about the dust problems we were seeing in Nikon D600 cameras. There was enough of a furor about it that when the Nikon D610 was released I assumed that the dust problem would be fixed. But I’m rather the paranoid type, and I never like assumptions, so as soon as the first D610s were delivered I thought it worthwhile to just double-check that assumption. Read more…

There is No Such Thing as a Perfect Lens

I get asked a couple of questions every time I publish a graph showing Imatest results for multiple copies of lenses like the one below. Most people understand that some copy-to-copy variation is inevitable in the manufacturing process. Most are surprised, though, at how large the sample variation seems to be. Heck, I was surprised at how large the sample variation was when I started doing this kind of testing. Read more…

Camera Gear Rentals is Big Business, and LensRentals Proves It

cicala1

Some people say that the secret to striking it rich during a gold rush is to sell shovels. That’s kind of what Roger Cicala is doing. With photography exploding in popularity as of late, Cicala has found huge success in loaning out gear to photographers who would rather rent than buy.

Disassembling a Tripod Ball Head to See How It Works

ballhead

This will probably be of limited interest to most of you, but we like to know how things work, not just how well they work. We thought we’d take a couple of pictures when we disassembled a ballhead in case any of you were interested. Our demonstration partner today was a Benro B1 ballhead that had a stripped tension adjustment knob, but all ballheads work basically the same way.
