Summary: I returned my copy of the E-M1 because the autofocus would not give a correct focus when a circular polarizer (and I tried two different brands of polarizers) was mounted on either of the two 14-42 kit lenses that I have, though the E-M1 did autofocus properly without a polarizer on these lenses. It did focus properly with any of the many other Olympus primes and zooms that I have, including Zuiko lenses with the mmf3 adapter, with or without polarizers.
Summary: So I have been using the EM1 for almost three months and about 12k shots....I have to say, a really versatile camera for many uses...the fringe events being high speed action (implying indoor soccer/basketball) and any video (terrible codec, purchased a dedicated camcorder). In all candor, likely to purchase a used D7000 and long telephoto for upcoming sports (a lot of value in the secondary older model markets).
Excerpt: I wanted a DSLR to take with me on hikes, events, etc where I did not need to have my heavy professional big bricks. I like the size and weight. But this camera body has a big learning curve for me. It is necessary to go carefully through the manual which comes only in PDF form. For some reasons, settings do not seem to stay the same for me. I normally shoot Aperture Mode....However, I am finding that the Scene modes are awesome, at least in camera.
Pros: Good in Low Light, Great Resolution, Large Clear LCD, Small / Compact
Excerpt: I've used Oly equipment since 1977, starting with a Trip 35 & ending up with two OM-4Ti's. Then, went Digital with an E-1 & later an E-3. In 2010, being concerned about the future of Oly, I studied my options and went full-frame Nikon with a D700, slowly adding lenses then, in 2012, a D800. Great stuff but big, heavy & bulky equipment. I still had all of my Zuiko 4/3 lenses & when the E-M1 came out, decided to pay the premium price for one and bought it.
Pros: Excellent Stabilization, Generally Good Efv, Good Battery Life, High Quality Construction, High Quality Lenses, Lightweight, Small / Compact, Takes Nikkor W Adapter, Weather-sealed
Excerpt: For me, this camera was a very tough choice. I still own my Olympus OM-2N (film), and always loved Olympus' innovation. But, I knew my "go to hi-res" would be a Nikon D810. After digging around quite a bit, I'd originally settled on a Fuji X-T1. I like the design, the lens selection, and the similarity of function controls to the D810. And I liked the "rangefinder look!
Pros: Bright Clear Evf, Easy to Use, Fast Shutter Speed, Good in Low Light, Intuitive, Large Clear LCD
Summary: Olympus OMD EM1 is an awesome camera. I used to be a Nikon guy with D300. i bought D300 for better quality from my friend but hated the size. I wanted a smaller size camera with DSLR quality. I purchased Nikon 1 series camera but was never satisfied with the image quality. I was waiting for one of the new Nikon 1 series which kept getting delayed so i thought to try out Olympus OMD EM5.
Excerpt: I'm an advanced ametuer and use this mainly for wildlife and scenery. It isn't a major upgrade from the EM5 but it is easier to use and better laid out than the EM5. With the 12-40mm f2.8 lens it is the perfect walking around camera. Very capibile and light weight combination. I love it and can't stop talking about it with my camera club friends.
Pros: Easy to Use, Great Resolution, Great Zoom, Large Clear LCD
Excerpt: Its a pricey upgrade, but the improved functionality over the E-M5 is worth it. However, the manual is terrible, and there are as yet no good 3rd party instruction books for the elaborate menu of controls. I wish they made a good grip-strap just for this camera.
Excerpt: I primarily use this camera for photos. Things that I like- I love how easy it is to use and all the additional button support for quick and easy adjustment on the fly. Battery life is decent but can be improved. I typically shoot models, cars, racing/drifting events, food, weddings, performances, vacations, family photos, and travel. Super fast shutter. From off to on, focused and captured within a couple of seconds.
Pros: Easy to Use, Fast Shutter Speed, Good Battery Life, Good in Low Light, Great Resolution, Great Zoom, Large Clear LCD, Light weight, Small / Compact
Cons: Evf Freezes Some Times, Evf Image Gone W Shutter, Lag / Shutter Delay, Limited Video Controls, Limited Video Support, No Headphone Jack, No Sound Monitoring, Short Battery Life
Excerpt: Great sensor. Feels solid and well made. Love the autofocus, very quick even in the dark with the 2.8 12-40 lens. Excellent photos in both RAW and JPEG. Great color rendition. Fantastic low light performance even at high iso's. Only problems are the battery which discharges very fast after some use, but the indicator showing a full charge.I need a second battery. The other problem is with the instructions. Not clear on some features, for example the panoramic photos.
