Olympus OM System MC-14 1.4X Rear Converter for Micro Four Thirds

Excellent. I thought I was buying refurbished because of the price. It was sent from Amazon Japan. Brand new in box and with pouch. I believe it took like two months, but well worth the wait. Excellent price, and brand new. I don’t believe one would need to buy this type of adapter with warranty, which this one does not have, as it is an import. Buy it !

Great price and sharp photos used with the 300 mm lens.

Item as advertised, shipped from Japan at a much lower price than available in the US, arrived very fast, 10 days earlier than forecast.

Complementa el uso de mi lente 50-150mm pro. Recomendadísimo

Appreciated the case that was included. Excellent converter.

Works great. The lower price due to it being still branded as Olympus instead of OM feels like a steal.

Work well with the Qlympus/OM Systems 100-400mm zoom. Initial test images seem to be at least as sharp as the 75-300mm zoom at similar focal lengths. Side note: the 100-400mm by itself clearly beats the 75-300mm zoom at similar focal lengths, as it should.

Versatile between lens and great clarity

Télé convertisseur de qualité monté sur mon 100-400 zuiko, aucune perte de piqué ! Je recommande vivement. Je pense bientôt acquérir le mc-20. Utilisé pour l’animalier et plus précisément les oiseaux.

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.

Wow .It works perfectly . Save me some money too.

Excelente. Ideal para el 40-150 pro f/2.8 y usable con el 100-400 de OM System. Además aumenta la magnificación en estás ópticas para usarlo en macro, y es utilizable también con el OM System 90 macro.

Perfect for 40-150 mZuiko 2.8mm lens. Drops aperture to 4.0 but still sharp pictures. Bought it on a on amazon through their Japan store for less than half retail price. Keep checking price as price fluctuates a lot.
