Olympus V321210BW000 M.Zuiko Digital 1.4x Teleconverter MC‑14 for M.Zuiko Digital ED 40‑150 mm PRO F2.8 Lens & M.Zuiko Digital ED 300 mm F4 PRO Lens, Black

I’ve been using the Olympus M.Zuiko Digital 1.4x Teleconverter MC‑14 with my M.Zuiko Digital ED 40‑150mm PRO F2.8 lens, and I’m thoroughly impressed by how well these two pieces of equipment complement each other. This combination is a game-changer for anyone who needs more reach without sacrificing too much image quality or portability.The MC‑14 is incredibly compact, considering the boost in focal length it provides. It feels solid, well-built, and weather-sealed—matching the ruggedness of the 40-150mm PRO lens. It seamlessly attaches to the lens with no wobble or noticeable play, which is something I always appreciate when working with accessories like teleconverters. The overall setup is still relatively lightweight compared to larger telephoto zooms, and I find it easy to handle for extended periods without feeling fatigued.The real magic happens when you start shooting. With the 1.4x teleconverter in place, the focal length of the 40-150mm jumps to 56-210mm, which gives you a bit more reach while maintaining excellent image quality. For most practical purposes, the sharpness is still very high, even at the long end of the lens. I’ve done a fair amount of bird photography and wildlife shots, and I’ve noticed very little loss in resolution, even at f/4 (the maximum aperture with the teleconverter in place).The autofocus performance also holds up remarkably well. The MC‑14 doesn’t slow down the focusing speed, and the lens continues to lock onto subjects quickly and accurately. This is a huge plus when shooting moving subjects like wildlife.One area where you might see a slight trade-off is in low-light conditions. The f/4 aperture at the long end doesn’t let in as much light as f/2.8, and while the in-body stabilization (IBIS) on my OM-5 does a fantastic job, you may need to adjust your settings or use a higher ISO in lower light. However, the teleconverter does a good job of preserving image clarity, and the slightly slower aperture is a small price to pay for the added reach.This combo has been incredibly versatile for me. I’ve used it for everything from wildlife and nature photography to landscape as well. The 1.4x teleconverter gives you a solid range of focal lengths that you can quickly adapt to, without needing to carry around a separate, heavier super-telephoto lens. If you’re like me and you want to travel light without sacrificing reach, this setup strikes a perfect balance. This is now my go-to set up for when I go abroad and want to reduce the weight in my luggage (I have the M.Zuiko Digital ED 150-600mm F5.0 which is great but too hefty to carry with limited baggage allowance).I highly recommend the Olympus M.Zuiko Digital 1.4x Teleconverter MC‑14 if you already own the M.Zuiko Digital ED 40-150mm PRO F2.8 lens. It extends your focal range and opens up new creative possibilities, all while maintaining a high level of optical quality. Sure, there’s a slight compromise in terms of light-gathering ability, but for the vast majority of situations, this pairing delivers fantastic results. It’s an excellent solution for anyone looking to get more out of their micro four-thirds system without breaking the bank or adding unnecessary weight to their kit.

I purchased this for the OM 90mm Macro lens, the extra distance you get is amazing, Dragonflies get ready.Update I have been using this with the 40-150mm f2.8 and can it delivers excellent sharp pictures, also auto focus is superb. Would recommend.

Great product at great price and delivered on time. Works perfectly with my om-1

Excellent product tested on the Olympus 40-150 mm f2.8 pro lens with superb results, however Amazons next day delivery failed miserably not totally their fault item was despatched via Royal Mail guaranteed I.00pm delivery in the event it arrived a full day later also the packaging left a lot to be desired manufactures box placed inside a flimsy envelope box arrived slightly crushed but thankfully no damage to the item.Amazon please take note!

This turns my 40-150 f2.8 from a 35mm equivalent 80-300mm lens to a 112-420mm f4 lens without really any noticeable fall in optical quality. The MC20 I have considered is still supposed to be good optically, but not as good as the MC14. I still may get the MC20 at a later date. Focusing is still lightening fast with the adapter. The adapters will work on about 3 other specific Olympus/OM lenses currently available. I highly recommend it.

Adds reach. Quality is better than I expected. Images good. At least, for me.

This 1:4 converter was purchased on the back of me buying the X2 converter (I did not rate that at all), soft and a let down. The 1:4 on the other hand has delivered a performance that was expected.. would I advise you to buy it? Yes with use coupled to OM lens’s that it’s matched to and made for.

Great quality converter. Very compact and no discernible loss of sharpness and only one stop loss of aperture.A little pricey but pales into insignificance against the cost of buying a longer lens.
