The (D)SLR camera simulator

A good friend of mine showed me the cute webpage of the “SLR Camera Simulator”. This simulator gives you the chance to interactively play around with a virtual camera that features the major controls any serious photographer should master: focal length, aperture, shutter speed, and ISO sensitivity.

If you are new to photography, this is a great way to get a feel for how a camera responds to your input. Of course you could (and should) also use a real camera to play around, but at least this little girl is more patient than any real-life human child. And the site gives handy feedback, too.

Joshua Sundquist: Real or Photoshopped?

Do you think this photo comparison currently doing the rounds on twitter is fake? Well so did I when I first saw it. Looks a little “fake”, right? In fact, someone in a forum calling herself “a professional expert in Photoshop” vouched for this photo’s fake-ness.

Review: Sigma 17-50 F2.8 OS vs Tamron 17-50 F2.8 VC

Today I am comparing two “premium” third-party standard zoom lenses: the Tamron 17-50mm F2.8 VC ($650, B&H), and Sigma 17-50mm F2.8 OS ($594, B&H). Both offer a useful 17-50mm with fast F2.8 max aperture (at all focal lengths). Both feature optical stabilization. Both are available for multiple camera mounts (including Canon, Nikon and Sony).

Interestingly the price difference in The Netherlands (where I live) used to be reversed, although recently the Tamron got more expensive and the Sigma much cheaper, so that they currently retail for €419  and €389 respectively (28 December 2013).

In addition to their similar specifications, these two have very similar size and weight, and compete in the same price range. Direct competitors, therefore. But which one is best?

I got my hands on both of them (Nikon mount), and put them to the test.

A stabilized Sony 50mm f/1.8 just published their review of Sony’s new stabilized 50mm f/1.8 lens, available for their NEX mirrorless system. The thing that makes this lens special is the fact that it combines a big aperture with optical stabilization. In fact, to my knowledge this is the fastest (lowest f-number) stabilized system lens (of any focal length) ever built!

Large apertures are great in low light situations. It enables you to gather more light, thereby letting you use a lower ISO value or faster shutter speed. Lower ISO means less image noise and better colours.

The “problem” with traditional 50mm primes (like those of Canon, Nikon) is that when you’re shooting hand-held you have to use a fast shutter speed (e.g. < 1/80) because they lack stabilization. If you had stabilization and were shooting a static subject you could probably have gone down to 1/10 and have used an ISO value 8 times lower.
The large f/1.8 aperture gives about 3 stops extra light compared to a 18-55 f/3.5-5.6 “kit zoom”, but you lose the 3-stop advantage you would have gotten with the kit zoom’s image stabilization. Since the advantages cancel out you instead have to use the same ISO value for either lens at its minimum usable hand-held shutter speed. But with the new Sony you can choose to apply that large aperture either for low ISO (useful for static subjects) or for fast shutter speeds (useful for moving subjects). In one word: versatility!

Why you want a large aperture:
fast shutter speed (less motion blurring) and shallow depth of field

The advantages of a “nifty fifty” go further than being able to use fast shutter speeds. These lenses are almost always sharp (at smaller apertures), small, light, and can render backgrounds with beautiful shallow depth of field blurring, known as “bokeh”. By also being affordable (often < $300) you will find one in the bag, or on the camera, of every serious photographer.

For the reasons stated above a “nifty fifty” works nicely as a portrait lens on cropped sensor DSLRs. For a great example, see this photo by Ana Santos :

An example of the great results you can get with a 50mm f/1.8
(such great bokeh is unachievable with a 18-55mm kit lens).

Reading the review we see that this new Sony lens has nothing to be ashamed of, and at $300 (available for pre-order at B&H) it is good value for money, too! It is not the sharpest lens at large apertures, but renders beautiful out-of-focus background “bokeh”. If you want sharpness you just have to stop it down. And, it is stabilized!

Conclusion: a very harmonious offering. The unique double advantages of a classical fast 50mm prime and image stabilization. Sony NEX users can count themselves privileged.

Flickr to update interface

Venerable photo-sharing site Flickr is reported to be on the verge of its most drastic (and long-overdue) redesign in many years. Tech website BetaBeat just reported that Flickr is adopting a new interface that will look more like Google+, and less like a whitespace-and-text-filled website from the 90s. The new look is set to be introduced on February 28th, with the uploader coming in March.

I’m a Flickr user myself and still find their moderate pricing combined with unlimited storage a killer feature. Furthermore their focus has always remained on making photography accessible and not social networking (I hope this doesn’t change). And they offer some pretty neat online photo editing via Picnik. Not to mention powerful privacy filters. But…

Unfortunately the website is a clunky dinosaur. When I have to share photographs of an event, and I want customers to view and download the photographs Flickr was always a bad choice. To download a photograph at full resolution you have to go through at least 3 click (or right-click) actions – each of them being slow. And the interface in general looks (and is) straight out of the last century. It’s probably telling that parent company Yahoo is still battling to get out of its downward spiral (having led to them to fire their CEO last year).

But things are apparently about to change, and I think that Flickr can still save itself. Despite the many other photo sharing sites Flickr still has a uniquely powerful name that is almost universally recognized. Probably their strongest competition, Google’s Picasa Webalbums and/or Google+ doesn’t offer unlimited storage, and is still too entangled in other services and afflicted by a niche/nerd image.

Thus – looking forward to the upcoming change!
