Olympus press release.

This is interesting to see how a previous article I wrote about the possible re-structuration of the photo market through some significant acquisitions has a nearly immediate echo.

Actually, Kenko-Tokina, one of the companies I was mentioning as possibly interested in moving forward, has officialized its acquisition of COKIN SAS, the French leader of filter making which had been an major source of innovations in the 1990s.

Random luck?

By the way, I also wrote a recent paper on filters in digital photography.

Press Release

PARIS — July 5, 2011 Kenko-Tokina Company Ltd., Japan today announced that it has acquired the famous French filter manufacturer COKIN SAS.

COKIN is the creator and leader in Square filters systems, exporting 90% of its production to more than 100 countries around the world.

Mr Toru Yamanaka (President of Kenko-Tokina Co., Ltd.) said: “I have always been impressed with the creativity that COKIN filters and accessories offer. I admire and greatly respect the professionalism of this line of fine products which reflect the French ingenuity. We are very proud to add this filter manufacturer to our Team.”

Kenko-Tokina Co., Ltd. was established in 1957 and now has 10 factories and subsidiaries worldwide. They are a world-leader in round photographic filters and other fine optical products.

COKIN France S.A.S.U. (new company name) will stay independent, with its own manufacturing, marketing and worldwide distribution network.

Mr Marc Heintz (Director of Sales, COKIN France): “Kenko brings to us a strong backing of finance and supply of raw materials, which will allow us to expand and bring new innovative products to the market once again.”

With this acquisition, both companies will expand their services and bring the flourishing photographic accessory market their expertise and enthusiasm for today’s exciting imaging world.

The price: less than US$350/300€ (or £816 in the UK).

Immediately available with the following lens mounts: Canon EOS, Nikon DX.

When buying a photo camera, we often research in order to decide if this is the best camera, if its features will be goo enough, but will it be robust enough? Will it be useful or necessary to purchase a warranty contract extension? Will it fail very soon?

When somebody asks me these questions (and it happens quite often since I consider myself some kind of photography expert), I am usually without good answers; Nobody really speaks about this dirty little secret: Reliability of photo cameras is a taboo issue. In most cases, talking only happens for very extreme situations (I will not mention any pro camera events in the past few years). But on a daily basis, will my camera follow me everywhere? will it survive the bad treatment I will apply? Or will it fail at the sight of the first cloud (of dust or rain)? Preferably just a couple of days after the end of the warranty period?

So, I decided to collect more than the usual information to try and answer these questions with more than: Entry-level cameras are too cheap to be robust, are less protected than pro cameras; And, mechanics fail more than electronics.

And, I found a few interesting articles with adequate documentation. Of course, they are the rightful product of the business of some shops repairing or renting equipment and accepting to share their data with us.

And I found interesting data. For example, there is nearly no information on photo cameras, or camera bodies. But SquareTrade published rather detailed report about the repairs they did in the recent years (though mostly on point-n-shoot cameras) with some frightfully clear conclusions, like:

• More than 10% of the cameras failed before 2 years
• The statistical projection tells that there are/will-be more than 15% failure within 3 years
• Accidents are a major cause for failure: 40% of cameras were broken in such a way; We are rougher than our cameras!
• The more expensive, the more robust
• For SLR cameras, Canon and Nikon go hand-in-hand

And to think that the failure rate of major brands is around 4% within two years for a camera whose price is nearing 1000€…

But, look at the graph below:

I would like to believe that you can extend these figures out of point-n-shoots and into the SLR market, but my own professional experience with quality and reliability management (in the automotive world, if you want to know) tells me that we should not even try.

On the opposite, I found additional data about interchangeable lenses to plug into our SLR cameras. Two studies from LensPlay and LensRentals bring some more light to the issue.

From LensPlay, hundreds of lenses and users have been analyzed: among the voluntary answers provided for Canon, Nikon, Pentax, Minolta/Sony, Tamron, Tokina and Sigma, only Minolta/Sony produced less than 200 answers (a pretty nice representation of the market).

LensRental gives us a finer status because they go down to a model-by-model level. So, it’s no longer necessary to compare brands, but you can get a good idea of which glass piece is more fragile or more sturdy than others, forgetting about the good (or bad) fames.

We also appreciate a lot some of the additional comments like:

• The super tele prime lenses (300mm f/2.8, 400mm f/2.8, 500mm f/4, 600mm f/4) from either Canon or Nikon are among the more reliable lenses (their simplicity is probably a good reason for such a score).
• The Sigma 120-400mm & 150-500mm had a 45% repair rate (as long as they were included in the LensRentals catalog of products).
• The Canon 50mm f/1.2 and Sigma 100-300mm are well under 10% (which is considered a good level in LensRentals)

Of course, these raw figures must be taken with a grain of salt: Rentals are often more mis-handled than bought parts, but the relative results are quite certainly representative of the underlying reality. And for example, the Canon 100-400mm seems to have an unfair bad fame about the reliability of its stabilization mechanism.

All in all, many reasons to treat your photo hardware with some care…

It is often difficult to group lens reviews in order to compare/evaluate a little more than their mere physical characteristics (focal length, aperture/diaphragm, or even number of individual lenses). But how would you evaluate/review optical quality? When I see the really impressive differences between two lenses, I would be prepared to judge from their price, but a cheap wide-angle lens is not always worse than a slightly more expensive one (well… if the price difference is really large, it’s not only an accident and quality explains a lot).

So, where should we go?

I collected the addresses of some web sites appearing quite able to provide this kind of quality reviews/comparisons/evaluations/tests (I try to be systematic, with your help, while telling what I believe are the strengths or the weaknesses of each one).

From here, I invite you to an orgy of lens reviews, lens tests, lens comparisons, lens evaluations. And remember to shoot some photos, too. It’s not only the lens which does the photo. Some are shot by telephones, if the photographer is an artist.
