This is a lens that I never intended to buy. Canon replaced the Canon EF-M 18-55mm STM IS lens with this one and now use it as the standard kit lens with different EOS M bodies. It is smaller and lighter than the Canon EF-M 18-55mm STM IS, but the construction isn't as solid and it feels more plasticky. The extra 3mm focal length on the wide end is useful, but for this you have to sacrifice 10mm of focal length at the long end. It's also slower, with a maximum aperture of only f/6.3 at the long end.

When I was searching around for the best price on my EOS M6, one on-line kit price I found that included this lens was cheaper than buying the body alone at my local camera shop. Therefore, it was the same as receiving a free lens. Considering that this lens retails for around $299 in the US I thought that the kit was quite a good deal, even though this lens will probably get very little use. In fact, I will probably wait until my daughter is a little older and then give her my old EOS M along with this lens.

User Impressions

This lens has the same lock that first appeared with the EF-M 11-22mm and the lock needs to be released before you can use it in order to get it out of the storage position. It's a bit fiddly at first, but you soon get used to it.

The EF-M 15-45mm is smaller and lighter than the EF-M 18-55mm, but larger than the EF-M 22mm pancake. The lens mount is plastic, whereas my other EF-M lenses have metal mounts.

The zoom ring is positive and has about the right amount of friction. At 15mm the lens is fully extended. As you start to zoom it retracts and reaches its most retracted zoom position somewhere between 24mm and 28mm. As you continue to zoom the lens then starts to extend again and at 45mm it is fully extended again, as it was at 15mm.

As with all EF-M lens, the manual focus ring is small and probably won't be used by the majority of users.

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.

Manual Focusing

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:

  1. AF (Auto Focus). When in this mode the focus ring is completely inoperational.
  2. 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.
  3. 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.
While holding the shutter release halfway down and turning the focus ring ring, you will see 'MF' blinking on the rear LCD. If the camera is in AF+MF mode and simply switched on, turning the focus ring does nothing. You must hold the shutter release halfway down before manual focusing will operate in AF+MF mode.

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.

Image Stabilisation

Canon's Image Stabilisation system has got better with every generation. The 300mm f/4L lens that I sold had first generation one-stop IS and although it was helpful, it wasn't that effective.

This lens has the latest four-stop IS system that has been around for a few years. It has somehow been packaged into this very small lens and works very well.

I didn't use a tripod for any of the sample images above. Some of the shutter speeds were quite slow and you can see that the lens IS system has done a good job.

Focal Length

This lens is roughly the equivalent of a 24-72mm lens on a 35mm (full frame) camera. It's a useful zoom range for a general walkabout camera and can be used in most situations.

However, when attempting some street photography I found myself zooming the lens to 15mm all the time and wanting some more width. I really longed for my EF-M 11-22mm IS STM and had I not been using this lens in order to test it, the EF-M 11-22 would have been my first choice.

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.

If this lens had been expensive, or if I had had high expectations of its performance, I would have been disappointed. As it was, the price that I paid for my EOS M6 kit with this lens included meant that the lens was almost free. In addition, after seeing the plastic lens mount, my expectations were very low. Therefore, I wasn't disappointed.

The sensor in the M6 is excellent and images from some of my other lenses really 'pop'. Images taken with this lens are satisfactory and - as you can see in some of the sample images - provide quite a lot of detail, but they don't really stand out.

I can understand Canon's predicament. The company wants people to buy into the EOS M system and most customers won't have any EF-M lenses already. With an interchangeable lens camera system you can't sell consumers a body alone because it would be useless. New buyers also need a lens.

The MILC market place is crowded and very competitive, therefore, a kit lens for the masses needs to be cheap in order to keep the kit price competitive. This was probably why the higher quality EF-M 18-55mm kit lens was replaced with this one, because this one is cheaper.

Maybe I sound too harsh because this lens will be perfectly acceptable for many people. If you are a 'normal' person who simply takes photographs of events in your life to remember and share those events, this lens will perfectly fine.

On the other hand, if you are primarily a photographer and not someone who regards photographs as a secondary concern you will probably want a better lens than this.

I don't plan on keeping mine. I will give my original EOS M and this lens to my daughter.

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.

Visit Thailand

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. I always use Agoda to book hotels in Thailand. The company was established in Thailand and has great local knowledge, as well as a huge inventory of hotels.

If you click on one of the destinations opposite you will get a list of hotel deals from Agoda. It's generally a good idea to book on-line because you will get a good room rate and you won't suffer the disappointment of arriving at a hotel to find that it is full.

I book hotels regularly in Thailand and I have always found Agoda to be the best on-line travel agent. At times I have spent a lot of time researching hotel prices and although other deals sometimes look better at first I always end up returning to Agoda.

If you don't wish to pay for your hotel at the time of booking, normally allows you to pay when you check in at the hotel. Some people prefer this method, but I have always found to be more expensive than Agoda.

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. However, you will normally find that Agoda is the cheapest and therefore you can save yourself time and money by just booking through Agoda in the first place.
