I have been researching a lot for finding an easy-to-carry, lightweight camera for landscape which also works in low-light conditions, long exposures and night photography. Please note, I am a photo-enthusiast and photography is not my profession.
I can compromise in image quality to certain extent and don't want high level noise introduced in high ISO(1600-6400 and above). The last thing I want is to carry around 10 kgs of camera and lenses around, because I plan to use the same camera setup for usual day shooting.
I have handled Canon 7D and a few Canon L lenses and do not like the combined weight of the camera and lens alone, as I am sure over time I will become tired of carrying the weight around. Thus, Nikon d7100, Canon 7D and other DSLRs while great, are not for me. For this reason also, I am not keen on A77 which is large and heavy(I think).
I am only considering mirrorless cameras and lenses at this point. The Sony A7r and Sony A7 are too restrictive in terms of body-price alone. While the Olympus OMD EM-1 has massive issues at ISOs ~ 1200-1600 and is not suitable for low-light and night photography(although everywhere else it is a very very good alternative to DSLR). It also has issues with long exposure.
I am curious about Sony A6000 but haven't seen many reviews online. Thus, Sony A6000 interests me but I do not know how it compares with Canons and Nikons(7D and 7100 respectively).
I want to invest in a camera which serves me well for next 2-3 years, also considering native and interchangeable lens.
Are there any mirrorless alternatives to APS-C DSLRs like Nikon D7100/Canon 7D considering IQ and ISO performance in low-light/long exposure?
The factors under consideration:
- Weight of camera and lenses
- Low Light and High ISO performance
- Night Photography Image Quality(IQ)
- Long Exposure
- Lens variety (current and future)
- Ergonomics and Ease of use
