It all started when I asked myself a simple question- do I have to carry my monster DSLR, or can I rely on my smartphone-camera to do the job? I reasoned, my smartphone can do panoramics, can upload the image to a site or my computer, can even edit the image to some extend. So I reasoned if I can compose well, can shoot in good light, I might be able to bring home winning shots with one of the smartphones like my daughter does? Can I get professional results out of these smartphones? The problem with that argument is that it totally ignores a few facts- the lens of the DSLR is 1,000x bigger and better than the smartphone, I cannot control the camera exposure much beyond the +/- exposure control buttons and who knows what would happen if I wanted to blow up the image beyond say, an 8×10. Therefore, I started to look at the smaller point-n-shoots and the mirrorless cameras. Can they do the job? The answers are quite unsurprising, but I thought I’d publish my rationale anyway.
To do a semi-objective assessment, I set up a flower vase about 5′ from a tripod, left about 20′ of space behind it to check for bokeh (more on that later). I then gathered all the cameras we had- an iPhone 5S, a Samsung Galaxy S5, a Sony RX100 II, a Sony A6000 with a Carl-Zeiss 16-70mm f4 lens and a Canon 7D coupled with a Canon 24-70mm L f/2.8 lens. Before I start, a note to the (nerdy) readers that are concerned about megapixels, sensor type, sensor size, RAW to JPEG conversion, etc. please see my footnote about these parameters2. For now, it is suffice to say that I was more concerned about portability and final use of the print than what sensors there are in the market or how many megapixels my cameras had. Also note, I could not normalize the f-stop or aperture because when a device is set to “automatic” (e.g. smartphones), the ability to control aperture is lost. However, I did try to mimic the apertures in all instances as best as I could. Since the cameras were on a tripod (or jammed against one) their shutter speeds did not matter (they were high enough to be hand-held). One last note- I did not analyze HDR in many of these cameras since the DSLR does not have a native HDR ability.
I decided to do a 5-star rating1 using the parameters that I thought were important to me and some of my friends:
To interpret the following tables, view the overall image to see if you like it subjectively compared to others. Next, look at the thumbnail images in the table. In the first first one, look for detail in the petals; the more detail, the better. In the second one, look for soft focus that does not show detail.; the less detail, the better. For other parameters, simply read my interpretation/notes.
This is one ubiquitous camera! Every other person seems to be carrying it. So how good is it really? Here is the image resized ‘for web’. I personally find the image a bit darker than others and the details are a bit muddy.
|Overall:||A great emergency camera but generally cannot be used for enlargements/professional use. Having said that, I have to admit that I have a huge 3’x2′ enlargement of the Eiffel Tower taken by my wife using an iPhone 4 hanging in our living room. The image looks more like pop-art than one with details and that is what makes it beautiful.|
||No need for a bag, extra batteries, lenses, etc.|
||Approx. $700||Even as a dedicated camera, the cost is not bad, but then iPhones are phones first and cameras later.|
||Not good at all. A lot of detail in the petals is lost. This translates into bad enlargements and overall “muddy” images (as compared to others of course).|
||The credenza edge is clearly defined and therefore, not a good bokeh at all. In fact, you can see quite a lot of detail in the credenza.|
This is probably the second most popular smartphone in US. The camera software interface has a lot of bells and whistles. For the following image, I used default settings. I personally find the image brighter than the iPhone, but everything seems to be in focus, even distant objects.
|Overall:||Another great emergency camera but like the iPhone, cannot be generally used for enlargements/professional use.|
