Olympus Τηλεμετατροπέας Φακού MC 20 M.Zuiko Digital ED Pro 40-150 mm

Good Points: does as is claimed. splash, but proof, light weight and compact. Improvement Points: no

Good Points: Very little loss of detail.

Good Points: Basically it doubles the reach of my existing zoom. I do a lot of aviation photography and whilst I have a 1.4 converter it sometimes isn’t quite enough, especially for small aircraft in the distance.

Good Points: Extremely sharp.

Good Points: The converter increases the scope for both the 40-150 Pro lens and the 300mm. Results are excellent, provided you make the necessary adjustments to exposure (trying to keep to a shutter speed fast enough to avoid camera shake - eg 1/600 sec when the converter is attached to the 300mm lens, 1/300 sec when used with the zoom fully extended.

Good Points: It’s light it’s versatile , I’m not a photographer who makes a living from my lenses , so yes it’s well within my spending range , it gives me the opportunity to go enjoy my day with excellent images. Improvement Points: The lens hood it’s too fiddly It’s going to break and I’m expecting that expense . Not something I should just expect .

Good Points: It works and gives a good image when used with the 300mm f4 PRO lens (I don't have the 40-150 f2.8 PRO so haven't tried it with that). The camera notes that the converter is attached in the EXIF data. Improvement Points: Long lens technique becomes very important with the lens attached, so you have to be careful if you want sharp images, even with Sync-IS. My own recommendation is that 1/1000 sec is best for this, but maybe with practice I will get that down. Given that the converter means f8, it is easiest on a bright day, assuming you will want to crop (as is usually the case with small birds). It is not a cheap lens, but is probably what you would expect a teleconverter of this quality to be. It might does reduce the image quality a bit, but I suspect the effects of camera shake are more important which makes it hard to be sure.

Good Points: Delivers excellent image quality (IQ). The IQ is so good that I have to check the EXIF data to if this MC-20 teleconverter was actually mounted! Well built to the very high Olympus Pro weatherproof standard. As a wildlife photographer out all day in all weathers it is invaluable. The Olympus MC-14 is equally good in all respects. Improvement Points: Autofocus locking on target speed is slightly slowed down but this is inevitable and common to all brands of teleconverters.
