Full frame -> Mft comparison. (Omg) ;) Sony a7r vs Em5 (with nokton)

compare-1 compare-2 compare-3 compare-4 compare-5 compare-6 compare-7 compare-8 Crop Crop-1 Crop-2

Most people, or atleast the slightly neerdier ones have a pretty strong opinion about weather this is “possible” or not. Comparing Mft to FF i mean. But here i go again.

The mindblowing detail of the 36mpix A7r sensor isn´t really there. When i sharpen pictures i look at them 100% so often it feels like the detail and sharpness is at best on pair with my Mft setup with Em5 and Noktons.

But when i zoom out, and see the “bigger picture” i realize thats not really the case. The A7r delivers “better” pictures for sure. Will i ever “use” the 36mpix and the “better” image quality? With 92.1 – 99.3% certainty, NO.

But thats not the reason i bought the full frame A7r either. The reason was mostly my Em5 is breaking apart, the shorter DOF, FF Bokeh and dynamic range.

At 100% the sharpness of the Noktons i had with my Em5 is on pair With my current set up. (But the A7r is 36pix so its actually alot less detail in the mft shots)

My Minolta MC 50mm f1.4 + A7r is a lighter package and delivers alot of “Bokeh for the buck” with great dynamic range.

But lets focus on the reasons i bought the A7r, DOF, Bokeh and Dynamic range, and i think this is where full frame is still in a league of its own. Sharpness and on many levels ISO is really good on the MFT system. Somehow the Em5, eventhough the pictures are noiser then lets say a Canon 5d mkii, there is more detail in the Em5 picture.

If one would do the math, Noktons f0.95 is not that far behind, thats about f1.9 on full frame, but the separation and pop i get with f1.4 on my A7r is really where it prevails. Bokeh is alot nicer on the lenses i have bought so far. Its not as “harsh” (now im beeng a little picky here, the Nokton bokeh is great) as the Noktons some times are.

DOF feels alot shorter even if the background seems blurred out to the same or similar extent the subject(s) seem to pop more.

And dynamic range, i still havent gotten used to it, alot of the times i push the trigger and think, “Thats gonna be blown out” but its not. I still cant belive how good on that regard it is, the dynamic range is a world of difference.

And one more great thing, Focus peaking! I had no ( or wery little issue ) with manual focus on my Em5 but now, with focus peaking. Why would anyone want AF? 😛 Siriously though, AF is great of course, but focus peaking is aswell!

I have an appointment in 30min so i gotto go, i´ll read through this later. Sorry if  the spelling is worse then usual.

  1. Hi Markus, If you can, I suggest trying Zeiss sonnar 50/1.5 it is one of the best lenses for a7 series. I’ve tried a few-mitakon 50/.95, Sony Zeiss 55/1.8, summilux 50, cron 50. To me sonnar has that rendering , 3d pop and lovely colours.

  2. Hi Markus, thanks for sharing your experiences… however, don’t you think that the shorter DOF is based on the focal length, 35 vs. 50mm equivalent? Well, I can totally understand your enthusiam having owned a Canon 5D two times. But I always sold it again due to the bulk involved… maybe the new Pentax would be an option for me, I still have 3 primes (24/50/85)…

  3. Hi! 🙂 Sure if you compare the 50 to the 35 thats part of the story. But it sort of feels the same with the Samyang 85 and Nokton 42 aswell. I´we shot the 85 @1.4 so the DOF is shorter. But i feels like its more to it then that, but thats probably just in my head (the real answer is problaby as easy as f1.4 = f0.7 on MFT. 😛 Perhaps the Pentax will be nice, havent read much about it but it seems great! Did you see the new Leica? Mirrorless,but bigger then a fullframe DSLR. Strange marketing angle. And the price point, 100 millindollars!(?) 😛

  4. hEllo! I have peeaked a little bit on the Zeiss, but the price is pretty hefty on that lens. But it sure looks good! 🙂 Perhaps in the future if i need better performance wideopen on a 50mm , for now i´ll settle with the Minolta 50mm, for the price, that thing is great! 100Us is pretty nice considering f1.4 and the more then good performance!

  5. Hey 🙂 Thanks for the reply – yepp, have seen the neuw Leica. Weird stuff for an astronomous price. I just don’t believe in pixel dustry or other magical fuss associated with optics 😉 My experience is that usually the extra price point does not translate into any better pictures – but it’s alright to admit having less buyin addiction and enjoying new toys ^^ That said, your shots with the minolta are great, no reason to switch from a reader’s point of view.

    Some day I may buy a cheapish A7 and fast manual 35… but for now, the V17/P25/O45 do the job 🙂

  6. Thanks for the comment! 🙂 And yeah i Also think the Minolta is great, i think i´ll stay for aslong as the camera holds togeather 🙂

  7. Yeah those are really sharp optics, and light, and small with AF 🙂 Perhaps not the cv 17 but the other 2. If one can live with Manual focus i think the a7 system is a great choise. The body is not the cheapest in the world but, the old manual lenses can be found on ebay for bargain prices and with great performance. A couple of hours on Flickr and then you know what to buy! But like you said, those optics get the job done!
