I will start of with this though, micro 4/3rds is FULL FRAME. It is a native format that has always been in itself full frame. One may notice that when I talk about full frame in the sense most will accept I will say 35mmFF. 35mm is also a full frame native format. If people want to harp on things then in reality the only true full frame would be 8x10 view camera format. Every other format of photography since the origins of view type WOULD BE CROP FORMATS!
This said yes Tommi is right in day to day use, printing, enlarging and display of images 9/10 people could not tell one digital format over another by just viewing images on line, from a hard drive on a large monitor, from 4x6 to 8x10 small prints to even HUGE prints wall size images, 20x30, 24x36, 30x40, 40x60 etc. Only if the viewers had a DIRECT side by side exact copies, printed to the exact standards, under appropriate lighting could likely more people begin to see any visual difference between the competing formats.
Yes! zooming up at 100% or 200% on a good computer screen showing the exact same images side by side may a pixel peeper be able to show any differences between formats. Yes, I look at the DPR resolution charts and will for curiosity compare my EM-1 and EM-10II to a host of other cameras. Zooming in and moving the box around the chart will show that 16-24MP cameras all have very minimal differences in resolution. Once you get to 36MP-42MP-50MP yes you can see a defined sharper more detailed images under the high magnification and side by side reference that DPR allows us to see.
Nobody argues that a higher rez camera does no give you more apparent detail. But in normal viewing even on large prints or zooming in on screen unless you have TWO or more images side by side you will not really notice any issues in resolution today.
Photographers were making 20x and 30x prints with even 3MP cameras about 15 years ago. Using 6-10MP cameras APS-C, 4/3rds, 35mmFF, about 10 years ago and the images were all judged as great as long as they were exposed properly, PP and printed well. Many a client PAID good money for such now LOW REZ imagery.
Lets move to noise. Yes, using the DPR resolution chart and moving the zoom box around the target area and selecting iso's from say 200 to 25,600 and picking a set of diferent cameras to compare, in most cases at notably higher iso say 1600+ m4/3rds as APS-C have similar noise structure. 35mmFF will all have less noise when viewing the target image zoomed in BIGLY with the moveable target box. Nobody argues this! But zoomed out to normal size or printed even to large prints nobody will notice the noise or even if at high iso see it to bother to CARE, if the image is worthy of viewing.
If I print out a well exposed m4/3rds image at say 20x30 or even 30x40 and even using a higher iso say 800-1600, H*ll 3200 iso and hung it up. No viewer will be able to tell me what format of camera be it m4/3rds, APS-C or 35mmFF made such image. ONLY! if they had a comparison of the same image shot with say a 35mmFF may they be able to tell one from the other. Many viewers still will not as they just lack the care, concentration or vision to see the differences. IN REALITY NOBODY CARES!
Same with dynamic range. Every m4/3rds, APS-C, 35mmFF camera made in the last say 2-5 years have higher dynamic range than ALL cameras made 10-15 years ago. But the images made on those 10-15 year old cameras still look as good today as when shot back then including dynamic range. 9/10+ people will not be able to tell properly exposed images made on a m4/3rds, APS-C and 35mmFF cameras for each's dynamic range be it 1 or 2 stops different. NOR AGAIN WILL THEY CARE! Yes, again in side by side by side direct comparisons may they see the subtle differences in dynamic range, but again nobody will care.
I'm not saying we should be ho hum over technological improvements be they resolution, digital noise and dynamic range! What I'm saying is that probably 95-99% of any viewers and if being a pro your clients none will care about any subtle differences. They only care if the images LOOK GOOD, if you are as a pro selling them what you promised.
So yes I get a general thrill out of new tech. I love the new EM-1II. I know it wont by its tech make my photography better. I control my quality of photography. If /when I buy an EM-1II, it may make some things easier for me, it may help just reinvigorate my shooting wants. I may buy it just BECAUSE I WANT IT! that is good enough if my budget allows.
If you like say Canon 1DXMKII or Nikon D5 and want either bad enough and can budget for $6000+ FINE BUY ONE OR BOTH FOR ALL I CARE! If I had a budget to buy the upcoming Hasselblad 1XD, I would likely buy one, BECAUSE I WANT IT! 90%+ of my photography would not really benefit by it though. But it would likely juice my photography pleasures up and yes its imagery would be better quality by standards even though nobody seeing such images would really care.
If I were to move to Sony 35mmFF mirrorless, it could be cool to have such and even higher rez but none of it will make me a better photographer. Yes, an A7rII with 42MP will make for a higher rez say 20x30, 30x40 print over my EM-1 but again unless the images made were side by side nobody will care.
So have fun with your cameras m4/3rds, APS-C or 35mmFF. ENJOY IT FOR WHAT EACH MAY BRING TO YOU! There is no right or wrong answer. For me shooting Canon DSLR for 11 years before switching to mirrorless was great, the cameras were all very good by my POV reference. But for me going mirrorless and to m4/3rds has taken me to a new place and a new level of photography pleasure. To me I find my EM-1 and EM-10II to be extensions of my photographic mind and style. So as a result I feel my photography may be better.
16MP cameras make to my eyes perfectly good images be they seen digitally or printed out. Zoomed up at 100% or 200% shows more than adequate details. Yes, I know a 42 or 50MP camera will give me MORE detail but to me it's more guilding the lilly. Nice but not needed, maybe I will have a 42-50MP camera one day. But I'm not losing sleep over this now. I loved my 8MP Canon 1DMKII. BRAWNY, good colour, good enough noise and high enough rez a GREAT DSLR!!! But I love, absolutely love my EM-1 in any way I can as a photographer. I also enjoy my EM-10II for its diminutive size.
We all can be picky, fussy, pig headed and full of bias over gear, so be it. IT'S ALL GREAT STUFF, Canon, Nikon, Fuji, Olympus, Sony, Panasonic, Pentax, Leica, Sigma and all the rest! Buy what YOU LIKE and enjoy!
