New Article: Reflections on reflections. Coatings: The Most Important Part of Your Lens
We are posting another article written by Roger Cicala at LensRentals.com.

Todays article touches on coatings. Their history, and their importance in optical design. As always, it’s pretty informative..

So How do Coatings Work?
It’s pretty simple to explain if you have a Ph. D. in optical physics and speak higher order mathematics. I don’t, so I’ll just have to explain it to you like it was explained to me (and I’ll put some references at the end of the article for those of you who want to double check the Trig and Calculus formulas). Basically, though, there are three types of coatings, each working in a different way. The first two types can be combined with each other to improve their effectiveness; the third type (nanocoating) is so effective it doesn’t need any help.

Gura Gear Kiboko 22L Preview

Gura Gear Kiboko 22L Preview

Introduction
I have yet to meet a single person that has purchased the “right” backpack for their needs the first time. I’m not saying that person isn’t out there, I just haven’t met him or her. I went through 3 different backpacks before I discovered Gura Gear.

This preview and future review will hopefully help at least a couple of people not fill their closet with camera backpacks like I did.

Gura Gear introduces the Kiboko 22L
Having bought and loved the original Kiboko  30L for my personal needs, I went out and bought a bunch more of them for my lens rental business. It just seemed like the perfect backback to carry large lenses and lots of other goodies on airplanes and into the field. I loved it so much we gave one away in a previous contest.

I had talked to Andy Biggs, the founder of Gura Gear a few times about the Kiboko 30L, and he let me know a year or so ago that new bags would be coming down the pipeline. Recently they have introduced the Chobe 19L-24L (which we’re giving away in the photo contest) and a week or two ago, the Kiboko 22L. This is smaller backpack sibling of the original.

Gura Gear was kind enough to send me a Kiboko 22L to preview, review and enjoy. This is the first article about the full line of Kiboko bags, this is a preview review just to give you an idea of what the bag is capable of carrying and initial impressions. I will go more indepth in the coming weeks. I will also be doing a preview and review of the new Chobe 19L-24L  and I’ll end it off with the best travel backpack I have ever used, the original Kiboko.

Marketing Stuff from Gura Gear
The Kiboko 22L+ was designed from the blueprints that our customers provided over the last couple of years while working out on Safari, touring southeast Asia, or simply shooting at home. Much like its more mature sibling, the Kiboko 22L+ is lightweight and durable, but this bag has a thing or two to teach big brother; like how to carry up to a 15″ laptop computer. Sized to fit the most stringent of international carry on requirements without sacrificing carrying capacity; this gem can carry up to a 500mm f4.0 lens in style. The Kiboko 22L+ was made to travel with a beefed up harness system that features memory-foam shoulder straps, a vented and padded back panel, a removable waistbelt and shoulder straps that can tuck away when not needed.

Initial Impressions
My personal preference with a backpack is the ability to be filled with a wide range of things. Some days I have no idea what I am going out to shoot, so I bring an array of camera bodies and lenses. I need to be able to carry a big supertelephoto, a medium telephoto zoom, a wide angle, a couple of camera bodies and accessories. I also need a place to stick a tripod. Most bag manufacturers haven’t figured out to do this effectively. Gura Gear was the first company that provided a solution that fit me.

I also needed  bag that I could carry onto an airplane without much trouble. The original Kiboko 30L allowed me to do this, the 22L will be even less conspicuous when boarding domestic and international flights.

The bag is without a doubt made to the highest standards in materials and build quality. The main material on the outside is a durable sail cloth material, this keeps the bag super light as well. All the stitching, zippers, shoulder harness and handles feel and look like they will never separate from the bag.

What can fit inside?
Below is an image of what I was able to stuff into the Kiboko 22L without any trouble at all.

All this will fit comfortably inside the Kiboko 22L

Laptop?
As you may have noticed, the Kiboko 22L features a laptop area that the original Kiboko does not. It can fit up to a 15″ laptop. I use a MacBook Air, so it fit perfectly.

Review Coming Soon
I will continue to use the bag on a daily basis and will do a full review down the road. I don’t believe you can adequately review a bag in a day or two.

New Article – Lens Genealogy

New Article – Lens Genealogy

Lens Genealogy
Ever wondered how a lens is designed, where it comes from or why things are done the way they are? This new article from Lensrentals.com’s Roger Cicala may answer some of those questions.

It’s a great article and well worth the read, just have some time for it.

I knew that today’s lenses are all designed using computer programs, but I was surprised to find new lenses aren’t designed from scratch. Designers start with an existing lens design and modify it. Of course, a lens designer doesn’t say “this lens really sucks, let’s use it as our starting point”. They start with a good design and try to improve it.

Leica M9 – A Second Opinion

Leica M9 – A Second Opinion

The Leica M9 revisited.
I’ve posted a new article as a follow-up to my original review of the Leica M9.

Judging by the comments I’m getting about the original review, there’s been a bit of a ressurgence in interest in the camera.  It’s probably due to the M9-P and a much more active used market for the M9.

I lent the camera to my non gear head friend John, and told him to write a little piece about what he thought of the M9. This is his story……
