The inclusion of an EF-M adapter to enable the use of EF and Canon EF-S Lenses makes the EOS M system very flexible. However, using big lenses doesn't do much for convenience and portability.
This little pancake lens is perfect for when I want the minimum configuration to make the camera as light and portable as possible. Roughly the equivalent of a 35mm focal length lens on a full frame camera, it's a useful focal length if you just wish to carry one prime lens.
This is what you get if you buy a Fuji X100, except that with the Fuji the lens is fixed and the only option you have to change the focal length is to clip on a wide conversion lens.
Personally, I don't want to be restricted to just having this focal length. I appreciate the fact that when I want to take a small camera with me I can just use the 22mm, however, I want to be able to use other lenses.
This lens is perfect for lightweight travel. Not only is it very small and light, but it's also fast meaning that you can probably get away with leaving your flash at home as well as all your big lenses.
The lens uses new stepper motor (STM) technology for its autofocus mechanism. This is all part of Canon's drive to implement silent continuous autofocus tracking in movie mode. To do this requires an appropriate body with a hybrid CMOS sensor and contrast detection AF technology, and a lens with an STM designation.
Autofocus is maybe not as fast as some other lenses, but in most situations it works well without any problems. For videographers the continuous autofocus in movie mode is a very welcome feature.
It also appears to work perfectly well when the camera is in AI Servo mode tracking an object coming towards the camera. I tested this on passing motorbikes and the results were quite satisfactory.
There is no direct physical connection between the manual focusing ring and the internal focusing mechanism as there is on other lenses. If you turn the ring with the camera off nothing happens. Turning the ring sends a signal to the stepper motor which then focuses the lens electronically.
With the EF-M 22mm f/2, the inner barrel moves in and out slightly while focusing. It only moves a small amount and there is no rotation.
Unlike my Canon EF and EF-S lenses, manual focusing isn't as easy with the EOS M system as simply turning the lens focus ring, or manually switching the lens into MF mode first and then turning the lens focus ring.
There is no AF/MF switch on the EF-M lenses and, because of the stepper motor technology and a lack of any physical connection between the focus ring and the focusing mechanism, nothing happens most of the time when you turn the focus ring.
To enable manual fousing, first you must go into the menu system and find 'Focus mode' (the camera icon with two dots). This mode has three options:
- AF (Auto Focus). When in this mode the focus ring is completely inoperational.
- MF (Manual Focus). In this mode the Auto Focus is completely inoperational and turning the focus ring controls the focusing mechanism whenever the camera is switched on.
- AF+MF. This allows the Autofocus to operate and also allows the user to focus manually after the autofocus has activated. However, you can only focus manually while pressing the shutter release halfway down after the Autofocus has activated.
When the camera is put into MF mode a small magnifying glass icon appears on the rear LCD in the bottom right-hand corner. Tapping on the icon cycles through 1x, 5x and 10x magnification with an accordingly larger image shown on the display. This is very similar to the Liveview feature on Canon SLRs.
In cases where the Autofocus mechanism won't do what you want it to do, such as with close macro work, this is very useful. Saying this, I have never used MF on my EOS M, which stays permanently in AF mode. The only time I use manual focusing is for macro work and the EOS M body isn't my first choice for macro.
I've included some photos in the sample images above taken with the aperture wide open. The bokeh isn't going to be the same as an EF 85mm f/1.2L lens, but it's fairly smooth and pleasing to the eye.
No Image Stabilisation
Just like the EF 40mm STM pancake, the design brief for this lens must have been to keep it as small as possible in order to achieve the desired 'pancake' form. Including IS wouldn't have made this possible.
The lens has a fast f/2 maximum aperture and the EOS M high ISO performance looks pretty good with little noise. Even in fairly dark conditions the lens is still very usable without IS.
Extenders and extension tubes
Currently, there are no extenders or extension tubes available for Canon EF-M Lenses. I don't know if Canon has any plans to make these items available in the future.
This lens comes with the new style Canon lens caps that can be released by pinching the centre of the cap. A lens hood and soft pouch are available but not included.
I find the focal length of this lens on a 1.6x crop camera far better for general photography than the EF 40mm f/2.8 STM pancake, which is too long with the extra 1.6x magnification.
On my first street photography outing with the EF-M 22mm I was encouraged by how little attention I attracted and the focal length was fine for about 70% of photos I took. However, I don't find it convenient zooming with my feet.
First I try to imagine the composition and then I often squat down for the shot. If the composition isn't quite what I imagined I want to be able to change it by turning a zoom ring, not by having to relocate myself.
Also, for the type of street photography I like the lens wasn't wide enough. I really like using the EF-S 10-22mm for street photography, but it is a bulky lens for the EOS M. I will buy the EF-M 11-22mm when it is available in my region. It seems as if it will be perfect for street photography.
The situation with EF-M lens availability has changed since I first wrote this information and at that time the ultrawide EF-M 11-22mm lens wasn't available. I now have five EF-M lenses (as well as some EF and EF-S lenses) and the following are my current thoughts.
During daytime when there is plenty of light my first choice of lens for travel/general photography is normally the EF-M 11-22mm f/4-5.6 IS because of the great perspectives it offers. If I think I will be photographing people more than places and things I may decide to use the EF-M 18-55mm f/3.5-5.6 IS instead because the longer focal length is more flattering for portraits.
However, when travelling I will normally return to base in the evening and when I go out again after dark my first (and normally only) choice of lens is the EF-M 22mm f/2. There are two reasons for this.
When I go out in the evening I want the smallest camera configuration possible and this lens on an EOS M body is very small. Secondly, in low light I want a fast lens and this lens also happens to (currently) be the fastest lens in the EF-M range.
Bearing in mind that as well as being small and fast it is also very sharp, if you have an EOS M mirrorless system it makes purchasing this lens something of a no-brainer.
Is it right for you? Do you need a lens that is small, fast and sharp? Do the sample images above look acceptable? They won't win any prizes, but they should give you an idea of the image quality for this lens. If the answers to these questions are yes, then it probably is right for you.
Would I Buy One Now?
Definitely. The Canon EF-M 11-22mm f/4-5.6 IS and Canon EF-M 18-55mm f/3.5-5.6 IS are fantastic lenses during the daytime when there is plenty of light. Having a focal length range of 11-55mm covers most of my needs in most cases and the image quality of both lenses is excellent.
For travel I find myself taking these lenses out during the daytime. However, when I go out in the evening I use the EF-M 22mm. Firstly, the main purpose for going out in the evening is normally to eat and I don't want to carry a lot. The EF-M 22mm, being so small and light, is perfect.
The fixed focal length doesn't provide as much flexibility as a zoom, but I can generally get the composition I want and the maximum f/2 aperture is very useful in low light conditions.
Original images were shot in JPG format using the EOS M's built in lens aberration correction. Noise was reduced using Imagenomic Noiseware Professional. Small amounts of image enhancement were applied using Adobe Photoshop CS2 (curves, levels, saturation) before sharpening using the Smart Sharpen filter (Amount: 30% - 120%, Radius: 0.2px - 0.3px, Remove: Lens Blur).
The large JPG images that open if you click on a thumbnail were saved with a 'High' quality setting of '8' on a scale of 0-12.

Thailand is an incredibly photogenic country, both for its landscapes and its people. Regardless of whether you enjoy large Asian cities, beaches and islands, or rice fields and mountains, Thailand has something for you and it is a dream destination for photographers.
One of the great things about visiting Thailand is that hotels are plentiful and a lot cheaper than in most other countries. Each link on the right will take you to the relevant page on the Agoda website where you can see photos, read reviews, and book on-line. I use Agoda to book all of my own hotels in Thailand and the Southeast Asia region. Agoda hotel rates are usually always the lowest and I have received good customer service, therefore I am happy to recommend the company to other people. Here is some analysis I did regarding booking hotels in Southeast Asia.
Booking.com used to be more expensive than Agoda, but when I have checked hotel prices recently I have found their rates to be quite competitive. Unlike Agoda, you don't need to pay at the time of booking with Booking.com - you can simply pay at the hotel when you check in. Also, Booking.com show you total prices whereas Agoda show you a price and then add on 17% for tax and service charge.
If you want to compare prices between different on-line travel agents (OTAs) for a specific hotel, you can use a company such as HotelsCombined.
