Sony RX100: pocket, meet camera

Photography is an interesting thing – many interesting things. Take cameras, for example. For some people, cameras and lenses appear to mean perhaps more than the actual photographs they are supposed to use those equipment for. The global growth of revenue from digital camera industry continues its upwards trend, and by some estimates is expected to reach $46 billion by 2017. There are cameras for multiple uses, and the strengths of one system in one context turn into weaknesses in another. Compare DSLR “systems camera” to a cameraphone (or smartphone), for example: the versatility provided by multiple, interchangeable lenses combined to large image sensor and powerful image processing is unbeatable when the pure technical side of photography as a form of expression is being considered. On the other hand, in everyday daily lives, few people go about hauling their professional DSLR system everywhere. Having a good camera integrated into the mobile phone is your best bet to have camera at hand when the spontaneus opportunity for an interesting photo presents itself. Though, the limitations of small lens and small image sensor inevitably set its limits to what one can achieve with a smartphone camera.

I am going to experiment next by acquiring a compact, “pocket camera” that hopefully would be small enough to actually be feasible to carry around daily in my overcoat pocket, while also having better optics and more versatile feature set than a smartphone camera.

My choice (balancing budget and wish list) concluded into Sony Cyber-shot DSC-RX100 model. This is a compact camera that was introduced already in summer 2012, and there are already several more feature-rich, upgraded versions of RX100 available (Mark II, III, and now also IV, released in summer 2015). My priority here though was to focus on the essential aspects of solid optics combined with decent image sensor and build quality, and the original RX100 ranks high in that department, and the price is pretty competitive by now.

There are few things that smartphone cameras do really well, and extensive app ecosystem, strong computing power in compact form factor and excellent touch screen interfaces are among the key such elements. If the lens and sensor are priority in a compact camera, to get that high quality shot, and you are carrying a powerful smartphone also with you everywhere, it does not make sense to try to duplicate smartphone functions in the camera itself. It is enough to be able to get the photo from camera to the smartphone, and then do the post-processing and possible social media sharing, or archiving from there (or, via a cloud service and/or a PC, for that matter). RX100 does not have a built-in WiFi or other wireless functions, so I have now equipped my new Sony with the Eye-Fi Mobi Pro 32 GB SD memory card, which has the WiFi, and can connect to e.g. iPhone Eye-Fi Mobi app, where from you can take the editing and sharing business as far as you want.

I also invested to some other small add-ons: the official camera LCD screen protector (PCK-LM15) and the Sony AG-R2 Attachment Grip. The latter affects the slim, flat design of RX100 a bit, but is really good for getting reliable hold of the camera so that you can confidently work through multiple positions, without fear of dropping the camera.

RX100 is one of the most popular cameras in the relatively new “enthusiast compact” category, that I guess emerged out of Darwinian adaptation process, where mobile phones took over most of the “snapshot” market, and the compact camera manufacturers were forced to evolve and differentiate their offerings from the most basic and casual photography needs. The manual of RX100 is a rather thick volume, so it has fair number of various options and functions, and this camera has also a rather large, one-inch image sensor (of 20 megapixels), a Carl Zeiss Vario-Sonnar T lens (28-100mm equiv., f/1.8-4.9), image stabilization, automatic face recognition, customizable controls and the ability to shoot recording RAW images – something that the more professional (or nerdy) photo tweakers can value.

It is still too early to say whether the idea of having a daily pocket camera available actually makes any real sense, so that the extra 240 grams of weight in my jacket pocket really pays off. But I guess that in those conference trip breaks this would allow one to jump on and off the “tourist mode” with a bit more expressive range available than just a mobile phone camera would allow. We will see.

4K Ultra HD monitor

Samsung U28D590D

Samsung U28D590D.

Sharper is better. I just booked the last remaining unit of Samsung U28D590D, an Ultra HD, 4K monitor from the local PC store (a display unit) at nice, 320 euros price. This is probably the most budget-consious alternative in 4K, 28″ monitors you can find; there are better, IPS screens (this is a high quality TN), and particularly professional models have better ergonomic in the stand (this is a completely fixed thing, and no VESA mounting either). But the colour reproduction, brightness are excellent, and particularly having 3840 x 2160 resolution at 60Hz, with 1 ms speed (over the Display Port 1.2) makes this pretty much what I have been looking for my gaming and photo editing needs. I am also regularly plugging in several computers (PC/gaming workstation, Macbook Pro Retina, Chromebook) to the same display at my desk, and there is interesting PIP (picture-in-picture) mode in U28D590D where you can keep an eye on the second PC while simultaneously working full screen on the other (let’s see how useful this will be in reality, though). If you think there is a better deal available from somewhere at the 300 euros price range, let me know. More information:

Edit: this is the thread with instructions for getting 52 Hz at 4k on the retina MacBook Pro 13:

Fixing crashing iPhone’s camera app

iOS 5 and the new iPhone 4S are not without their bugs, even while mostly being on the ‘it just works’ department. One rather nasty one that just jumped on me is the iPhone camera & camera roll application crash issue: the monent you try to access any of your photos, or when you try to shoot a new one, the app just crashes. This issue has been around in various forms for more than a year now, it appears, so I am not sure this is related to iOS 5 or recent hardware. Apple care appears to either recommend totally wiping your device to factory settings, or they have even replaced the malfunctioning phone with a new one. There appears to be a fix, however, that solved the issue at least in my case. You need to download software (e.g. iExplorer) that you can use to delete any ‘sqlite’ marked metadata files related to your photos, and then let iOS rebuild its photo database. I am not sure what is going wrong, but I truly hope Cupertino will take notice and fix their OS soon. For more detailed instructions, and thanks for spreading the word, please visit the iPhoneInCanada site:

Summer is here

Summer is here
Originally uploaded by FransBadger

The exact point when summer starts is hard to define, weather and calendar both playing their tricks. When your summer vacation starts can set a fuctional entry point for most purposes.

There has been more administrative and various reporting & statement writing work dragging into June than ever before. I am really looking forward to a break; no word that I would be using my hard- earned vacation days for writing my own research, like in so many summers before. That means that I wont be publishing anything, but – that is academic reality this year. My personal goal is to cut radically down administrative duties during the next academic year and work my way back towards doing my own research more. Lets see how that will work out.

Meanwhile, still a couple of days in the office, and then – off we go!

EOS 550D with RÖDE Stereo Videomic

Continuing blogging about my experiments with the new Canon EOS 550D: my first tests with the video audio point out that there is actually no sense in attaching an external mic to the camera right now. The AGC (automatic gain control) issue is much worse than what I thought. Here are two tests, the first with the internal mic, the second shot using the Röde Stereo Videomic, and in this latter one the “hiss” is almost intolerably loud:

Apparently the sensitivity of Röde is different from the internal mic, and the automatic gain control keeps on boosting the sensitivity up, until the audio becomes saturated with the background hiss.

There are a couple of potential work-arounds to this, but neither makes me very happy. The first one is to wait for a patched firmware to Canon EOS 550D; it is unlikely that Canon will provide a way to turn off AGC through the official firmware, but there are unofficial projects working on this kind of things. The most famous of these is the Magic Lantern project, but it is highly uncertain whether they will ever produce a hacked firmware for EOS 550D (the main focus is on 5D). More:

The second way that I know about is the “bypass trick”, where you fool the AGC to keep down by pushing synthetic tone to the other audio channel, and record your movie to the other channel. In the post-production you can then remove the extra channel. There is this video that explains the technique:

Neither way is that kind of quick fix that I would be hoping for (and I am not interested in plugging in extra sound sources every time I will be recording a short video clip), so any further ideas or advice on how to work around the AGC issue in EOS 550D are highly appreciated.

Testing the EOS 550D

EOS 550D, originally uploaded by FransBadger.

Ok, my new SLR arrived today (sans VideoMic & Eye-Fi card, those will arrive a day or two later), and it is time for the first impressions. Firstly, it is a real pleasure to shoot using this thing. It is much faster than my 350D used to be, and the large, sharp LCD display makes a real difference. The photos immediately jump to life, and it is possible to get right kind of feedback while trying to get the right tones, field of depth, or exposure. Also, since the camera is so light, it is easy to handle and I can picture myself carrying it around in our regular family travels. I have not got time to test the Full HD video properly, but it seems to be sharp, and camera easy to control while recording. There are some settings I still need to check out from the manual, though. AF point control, for example, was still evading me. It is good to notice that all the controls automatically feel like they are on the right places. Probably that is because they are mostly on their old, EOS-style places, on the other hand, the few changes feel natural and motivated. A good camera. Here are some test shots uploaded into Flickr.

Going for Canon EOS 550D

Photo (c) Canon 2010It was five years ago (time really flies!) when I got my previous Canon SLR, EOS 350D. The photos from the very first session should still be here. The body is still working fine, there are only a couple of dust particles inside, but the feature standard and user experience of today’s top cameras is completely different from 350D. I have now placed an order for Canon EOS 550D (with the kit IS zoom lens), and the key features are worlds away from the 2005 situation:

  • 18 million pixels
  • Full HD video (1080p)
  • DIGIC 4 processor
  • sensitivity range ISO100-12800 (extended, 6400 native)
  • 3 inch LCD display, 1040k pixels (live view — the quality of in-camera image display has grown more and more important during the years)
  • etc.

The manual for this thing is 260 pages (there is some reading and learning waiting for me) Continue reading
