Just managed to order an elusive EF-M 18-150 for delivery tomorrow (Monday 9th). Can't find a lens hood for love nor money, so I'll have to be patient. Have found one subjective review (in Dutch) that says it's sharper than the EF-S 18-135 STM (via the adapter) even wide open, and have also found some sample images at low-res from one owner with an M5, but there's very little out there at the moment. I will try and post some sample pics and 100% crops ASAP taken on my original M, although the weather here in the UK is due to be grey and wet tomorrow, so please bear with me.
Despite the weather being absolutely dire here today, I have managed a few shots from an open window across the valley, and a few indoors, enough to get a first impression. I won’t post these pics, as they are not ideal.
Firstly, the thing many people seem to be hung up about – yes the mount is plastic, just like the EF-M 55-200. I personally don’t have an issue with this at all. The rear element however is extremely close to the back of the lens; beware of finger marks or worse when putting the end-cap back on!
Physically it’s about the same size as the aforementioned EF-M 55-200, but it has a 55mm filter thread rather than 52mm on the 55-200. I mentioned that the lens hood is not yet available here in the UK, but as a stop-gap, the hood from the EF-M 11-22 fits, so it will give me some degree of physical protection in the short-term even if not ideal for light shielding.
Now for a quick image assessment:
At 18mm (f/3.5) there is quite a noticable amount of barrel distortion, but not unusual in a lens of this range. Corner to corner sharpness is good, even without the lens optimisation in DPP. There appears to be a small amount of CA, but nothing worth worrying about. Initial thoughts are that it is at least as sharp as the original EF-M 18-55, but I need better weather without rain to show you worthwhile examples.
At the telephoto end there is a small amount of pincushion distortion, but again, nothing unusual. Unlike the EF-M 55-200 which seems to soften towards the far end of the zoom (well mine does anyway), the EF-M 18-150 seems to retain a good level of detail and sharpness even at 150mm wide open (f/6.3). I don’t have an EF-S 18-135 STM to compare it with, but I do have the original non-USM IS version, and this EF-M 18-150 wipes the floor with it IMHO.
The weather promises to be brighter and clearer tomorrow, so I will do some more representative image tests. Even with the limited testing I’ve been able to achieve today, my first impressions are very good, and it will almost certainly be my walkabout lens of choice, with the EF-M 11-22 as the second.
