Hi guys,

I am thinking of getting a mirrorless camera, like olympus em-1 or sony A7

basically i am thinking to get it more for ease of using and light to bring around.

anyone have experiences to share of it?

I have a question that sony is full frame camera..which mean a bigger sensor and won't have crop factor on lense.

will a full frame camera provide more details and resolution of images? there are a lot of talks about A7 and A7r, it seems A7r will give better for big printing output so for digital usage it is not necessary?

I took a Sony Nex 5 and a 3N on a trip earlier this year. Both bought cheap, used. Very nice image quality and the portability is excellent. I used a Sony 16mm lens and a Sigma 30mm. The Sigma 30mm is a great lens.

Downside. I really hated the Sony menu system. It's like Fisher Price or Microsoft Windows. And I hated the fact that using these cameras requires so much interaction with the menu system. Most of the time I could not get used to not having anything to look through. Though in ideal light you can use them like a TLR which works quite well.

Sold them on when I got back and bought a used Fuji XE1 with a 35mm lens. I had been resistant to the idea of electronic viewfinders - but it's great. Better in some ways than many optical finders. So great that I finally got around to selling much of my Nikon gear. (I had also been slightly sceptical about Fuji - but the design and build quality is fantastic).

That little Fuji has totally reawakened my interest in taking photographs. I am taking pictures with that camera which I would never have taken with a DSLR. I never want to go anywhere with a bulky DSLR ever again.

I have the Olympus OM-D E-M5 with the 12-40mm pro lens.  Not a cheap bit of kit, and it does take some getting used to, but it's a useful tool in some circumstances;  that said, I'd always prefer my Canon 5D II whenever possible, but there are times when I don't expect to be taking pictures, or I do expect to be walking a long way, when it's a good thing to have along.  I'm too old to be lugging that 5D brick and its L lenses everywhere!

Quality is not up to the full frame Canon, obviously, especially in low light (high ISO), but it's more than good enough most of the time, and certainly for microstock.  Acceptable to Alamy too.

Not fast enough, in my experience, when using autofocus in servo mode - it just can't always keep up with the target - but provided you're aware of its limitations, it's a good thing to have available.  Video is good too, especially with the image stabilization.

I don't use it all that much but I am glad I have it.

I recently got a Sony a6000 and I'm crazy about it.
