Which is a great DSLR buy these days? It is Pentax K-01 or Canon EOS-M, for most of us

Having used several DSLRs and mirrorless cameras, I can say Pentax K-01 is a great camera- one of the best image quality out then in below $1000 cameras. Pentax used to sell for around $900 but their gamble with the style backfired so they are clearing them out. They currently sell for around $400 with a nice 40mm 2.8 lens.
Similarly, Canon was too late to enter the mirrorless camera world. They came in with Canon EOS-M with full APS-C sized sensor and started selling it for around $700. They put the fastest kit lens on this EOS-M camera compared to lens on any sub $1000 canon SLR. It comes with 22mm F2.0 lens!! This camera has same sensor and technology as Canon T4i but in much smaller body. This actually works very well for shooting HD video than most consumer Canon DSLRs. As of this writing (July 5, 2013), Amazon is selling Canon EOS-M for $299!!! Really a steal if you are buying it for less than $400. Let me tell you one major problem though! It does not come with flash! This can be a deal breaker for many and that is why I think Pentax K-01 can be a better deal for most of us.
Very shortly, both cameras are likely to be selling for around $500 or more. If that is the case, look for Used cameras too. Under $350, each of these cameras are great deals IMO.

Canon EOS-m or Pentax K-01

Check Canon EOS-M prices on Amazon.

Click on the link above and read the reviews yourself. Or see the summary here.
First, bad about this camera:
  • Lack of optical viewfinder- if you actively use viewfinder, this camera is not for you. LCD works fine for shooting but once in a while, in some bright sunlight, you will miss a viewfinder.
  • Orthodox style of Pentax k-01- see if you like the style. It is not bad as such. I see this style as an advantage. Most of my subjects don't take me seriously with this camera in my hand. They think this is a toy or some fun camera and I get candid photos. When I used to shoot with black bulky SLRs, mostly my subjects will become too serious or too conscious.
  • Flashy Yellow color- it is a bright nice color but if you don't like it, it comes in black and white color too.
  • Slow Auto-focus. Out of the box, the camera's AF system is slow but with firmware upgrade, it is comparable to most DSLRs. Howeve in plain contrast-less situations, like many other DSLRs, this one still struggles with AF. I immediately change to Manual focus mode and with focus peaking and Auto-zoom of the image on my screen, my workaround works very well.
Now the good about the camera:
  • The image quality is excellent. I have not seen such good image quality in any camera I have used so far which includes Canon T3i and Panasonic/Olymplus mirrorless m4/3 cameras.
  • With included 40mm lens, you can take impressive portraits and low light photos. If you like to take photos of people, this lens works out very well. In consumer grade DSLRs, Pentax K-01 has the best lens out there. Period.
  • If you like to take landscapes, the HDR mode does wonders. Easy to use and brings in details in shadows and highlight does not get clipped either.
  • With same K mount, in body Image Stabilization, and now Focus Peaking, using my Super Takumar 50mm 1.4 lens is easy and it helps get accurate focusing. K-01 body and Super Takumar lens (with combined cost of less than $400) help me take portrait photos that can compare very well with full frame $2000 plus DSLRs. 
  • Takes HD Video but use Super Takumar above in manual mode with wide aperture for video and you will love the quality and background blurr in videos.
  • This camera is compact and its odd look lets you take candid photos of people. Bulky SLRs many times make people too serious while being photographed but with box type camera, your subjects are less likely to take you seriously but when you show them the photos, they will be amazed.
Very likely, in 10 years, this camera will sell for more than what you are paying today. This is my humble opinion and don't base your purchase decision on it.

Which camera is better for concerts?

Compact Cameras:
If you don't have a pressing need for photos, my advice is to enjoy the concert instead of trying to taking photos or trying to shoot videos.
Shooting in a concert a tough battle for most people. Your enemies are too powerful LOL
* First, shooting in concert is always a challenge. Fast moving objects and flashy light.
* Most fixed lens cameras have tiny sensors which will fail to capture sufficient light to capture clear images.
* Many times we have seats far back so the camera will get even less light than someone in the front seats.
* Sometime we think a 36x optical zoom would be useful but if you zoom in, the shutter will be even slower and because of zoom, any small shake in your hand will be magnified.

So why not enjoy the concert and if needed, take a photo or two with your phone. However if you are determined to try and if there is good light, you may be in some luck. Here are some tips to get the best with your point and shoot compact camera.
* See if you can take along a tripod. If you are zooming in, a tripod can give you much needed stability for recording.
* It may sound tempting but try to avoid too much zooming in.
* Also try to shoot in 720p or lower instead of full HD like 1080p.
* Also if you can control fps, try to keep it as minimum as possible.
* Try to bring along a camera that has as big of a sensor as possible.
* A camera that has smaller F or f number will also work better than cameras with higher F/f numbers.
Good luck.


SLR cameras or Cameras with larger sensor:

Even most SLRs have tough time shooting in concerts. Said that there are few alternatives. If you can buy a Full Frame advanced Nikon or Canon camera that costs $2000 or more, and can buy some expensive lens, you will have better odds for good photos. Now with such big professional cameras, you are more likely to be stopped at the gate and told to leave the camera behind because most concerts don't allow shooting with professional gear.
Now here is a one cheap alternative that I have recently started using.
* I am going to recommend you a camera provided you like its style. However the style is not that bad and as such it can work to your advantage. Most concerts don't allow Professional cameras but this 'weird looking' camera can often be looked on as some toy or some old camera. It will have better odds of being allowed in. (There is another benefit with its boxy style. When I have T3i in my hand, my subjects become too serious seeing an SLR but with my boxy camera, I am able to take more candid shots.)
* I am talking about Pentax K-01. I have not seen any sub-$1000 camera do as good job in low light or with ISO as high as 3200 as Pentax K-01. It is currently selling for only $360 on Amazon. This camera used to be around $900 but Pentax's gamble with styling backfired and now they are clearing them out. This is a monster when it comes to image quality and low light shooting.

* The kit lens on K-01 itself is worth $200.The other benefit is that with Pentax, you can easily use old cheap lenses like Super Takumar 135mm F2.5 which works awesome in concerts and games. It is a manual lens but unlike Nikon or Canon, Pentax K-01 offers AutoZoom with manual focus and Focus-peaking which comes pretty handy with manual focusing.
* On a cloudy day, I was shooting with K-01 and a 30 year old Super Takumar F1.4 lens and my friend was shooting with his Nikon, we compared photos from both cameras. Within a week, my friend bought K-01 and is now looking for Takumar lenses too. Here is a photo of her daughter with this $450 combo of Pentax and Takumar:

* For video taping, Pentax does a nice job too. 1080p. Search on YouTube for Takumar 50mm and you will see that many serious minded SLR owners buy Takumar to take professional grade videos.

I will post links to some videos I have taken with this combination.
