Sony A7 from micro four thirds advice.

Shoot f8 on a D750 or m43 versus an A7 and let me know the difference in the number of keepers you have.
Why would I need to do that? I use the strengths of the camera to confirm focusing before I take my shots. I also have the option of checking straight away if I missed anyway, which is possible with any camera. I'm know the E-M1 is faster to focus, but it's not a full frame camera and it's not what I want to use so what's your point? As for the D750 I wouldn't know, it's not a camera that will ever interest me, it's a DSLR, enjoy carrying and manual focusing with that behemoth is all I can say to that. No camera is perfect to focus in any light, none, having used film cameras and microprism focusing screens I can say that modern mirrorless cameras are a pleasure to use and focus. Focus peaking and magnified live view make it virtually foolproof, no need to adjust for different lenses and all that hassle, I'm not sure what the problem even is.
 
I went from Oly EM1 (I still have the camera) to A7Rii and I must say I am disappointed with pretty much everything Sony has to offer compared to the Olympus. But that is just me. If you don't print large and don't need crazy shallow DOF, then stick with the Oly.
I somewhat agree with you though my experience is with the A7ii. The reason to go with Sony is if interested in FF (which trumps m43 with respect to high ISO and DR potential) and one likes the Sony UI/form factor. The big red flag for the Sony FF system has been the low light AF, a non-starter issue if a good light shooter or using primarily MF lenses. Battery drain? Just own extra batteries (like I did when owning the A7ii).

The really good news is that the Sony system is quickly evolving, both the bodies and lens selection. If a RAW shooter and someone interested in pushing the possibilities with RAW files, a FF camera is a no-brainer...for me, easily one of the best photography choices I have made. If shooting with MF lenses and concerned about weight, the Sony bodies very quickly are discounted given the number of A7 models and how quickly Sony cycles to next gen models. Personally, if I was still interested in the Sony system, I would never buy a new model right away. If shooting MF lenses, I'd go with an IBIS model and look for a heavily discounted A7ii

I'd keep the m43 system for telephoto shots or buy a 1" bridge zoom to cover that range..

It's less than a stop. If noise is the issue, an "S" would be better.

Noise + color fidelity + video + resolution is more than a stop. I can't compare an m43 to 1" without batting an eye. Neither can touch a modern FF sensor unless you are just looking for low ISO or autofocus performance.
The image above proves my point. Colour, video and resolution have nothing to do with f-stop differences in noise. Resolution wise, true resolution, the Sony 24mp sensor may have a real 30% advantage on the m4/3rds provided you use a lens comparable to the current Olympus Pro (or older Olympus HG and SHG) lenses. If you are concerned about resolution across the frame and sharpness (as distinct from resolution since they are not the same) and you want the edges to be nearly as good as the centre, with 35mm sensors this becomes a much harder proposition.

Well you can always downrezz a higher resolution image to improve it even more, or make the noise less noticeable. As it happens there is much less noise at low ISO's and when post processing as well. Colour fidelity and tonal range are also much better maintained at higher ISO's on a full frame sensor, as you'd expect them to be, it isn't purely about the noise itself.
Resolution wise, true resolution, the Sony 24mp sensor may have a real 30% advantage on the m4/3rds provided you use a lens comparable to the current Olympus Pro (or older Olympus HG and SHG) lenses.

Not really, I have 40 year old lenses that will do that pretty easily. Here's where you really see a difference.

Yes, I agree about DR, colour fidelity, etc, just noise control has been overstated on 24-50mp sensors. But I'd honestly check any 40 year old lens wide open. I've yet to see one that was really good. Stopped down is a different story, the lack of 35mm sensor's susceptibility to diffraction (it begins to show on m4/3rds at f/9.0) means no issue stopping down old lenses in order to gain decent across-the-frame sharpness.

Possibly, but downrezzing cures that, if you need to.

Wide open I'd agree, no full frame lens is sharp across the frame wide open. However, I have an old OM 50mm F1.4 which sharpens up very quickly. That being said, being sharp across the frame wide open isn't a particularly sought after trait on a fast full frame prime. The dof is so shallow anyway it's not really an issue, at least to many.

True enough though I've seen diffraction showing on m4/3's lenses below F9, it just depends on the lens to be honest. Deeper dof often offsets the effects of diffraction anyway, depending on what you're shooting. Either way, on both formats, some you win, some you lose, you just pick your preference, I use both for different reasons, both are great.
 
I went from Oly EM1 (I still have the camera) to A7Rii and I must say I am disappointed with pretty much everything Sony has to offer compared to the Olympus. But that is just me. If you don't print large and don't need crazy shallow DOF, then stick with the Oly.
I'm curious to know why you're disappointed with the Sony, only because I've had such a different experience also coming from the EM1 (which by the way I'm going to keep, and indeed am looking forward to the 4.0 firmware upgrade).
 
loved that camera but for high ISO performance. About 3 weeks ago I got the A7RII plus the Sony 55 and 16-35. Aside from amazing high ISO performance, the resolution of the Sony images compared to my EM1 is simply no comparison. The Sony trounces the EM1 and leaves it in the dust.
Yes, 42mp camera will outresolve a 16mp camera handily. Not really news at all.
A 16MP M43 sensor acts like the center of a 64MP full frame sensor. Put the same 300mm lens on both cameras and the M43 sensor will out resolve the FF for objects in the distance. Similar is true with the same macro and tiny details since there is limit to how close one can get. If one can get close enough to put a subject in the whole frame, the the A7Rii EASILY out resolves the 16MP M43 sensor. For most photography this is the case, but not always.

The A7s owners will say it does not matter.
Even 20mp over 16mp is noticeable, if not large.
I've never seen anyone say 'large' before. There was a little difference when Sony briefly went from the 16MP to 20 MP sensor, but not large.
 
You and Rich make good points. There are reasons to shoot with both and I'm wary and weary when someone slants everything in favor of one format as the superior choice for everyone. One of the reasons I want to keep a 4/3rds or m4/3rds body in use is I still really like my 4/3rds lenses and the peach lenses like the Uber Pro f2 zooms are really cheap since Olympus dumped DSLRs. Still love those lenses. I wish my Sony could mount them and use them in crop mode. I find Olympus gear to be more robust than Sony gear and it typically costs less.

m43 has better JPGs, better focusing, and smaller lenses. There are more choices for those on a budget too. For many types of photography these advantages may swing the deal. But I also really love my A7 and legacy lenses. If I could I'd buy and XT-1 and A7Rii to play with as well. But hey, I'm lucky as is.

Cheers, Seth

True and how often outside of a zoo can people do (for example) wildlife photos without having to crop empty frame away? But then you can counter and say, if you have the money, Sony has 500mm lens for their 35mm-sensored cameras which will give the frame-filling capacity of a 16mp m4/3rds with a 250mm focal length and you'll have 42mp on the subject. The "equivalency" thing goes out the window if Sony exceeds m4/3rds resolution by virtue of having longer lenses.

OR better yet stick to your Celllphone instead..done.
I love being able to just keep adding to my ignore list people with such comments.

Yeah like lets forget DR, MUCH superior ISO performance and so on....but the way I see it, if you own a camera and somehow IQ is the least important thing for you about it...then why not just go back to your phone...?

I think too much people here believe they can just spend the money on higher end gear and somehow the camera will magically make them better photographers then blame the gear when it does not happen.

That is not how it works...you got a MUCH more powerful piece of gear but dont expect it to do it all for you ;)

Going to a camera with better DR or noise control (even a modest 1 stop improvement) might give the average shooter a small improvement in what they produce. If it's worth the extra money or if it gives them a psychological "boost" at least they get something out of it.

Practicing technology agnostic here, and I think a stop is a lot of difference in and around the home. The RX1 gave me pictures I just could not take without a manual lens in m43 or camera phones. The A7S gives me video much the same. The gear can and does make a difference at the margins, where a lot of noobs shoot.

Now outdoors, good light, I'll say this: it takes a special kind of purpose to show the benefit of FF - bokeh or resolution perhaps, but not much else. I'd take an FZ or RX camping or backpacking over both m43 and FF - but not indoors, no chance.

More like, it's at the margins because they don't know how to use their cameras as well as they could.

I think that much of what constitutes a better image is intangible, because actual studio tests and measurements don't point out a huge difference between the cameras. It's like when people used to use different film sizes. It was hard to put your finger on just why the images from larger film looked better, they just did. Case in point, I once saw two images, one taken with a 4x5 camera another with an 8x10. Blown up to 16x20. The 8x10 image looked better, but it really shouldn't have if you went by things like resolution and DR.

Not for me, as a long time 4/3's and m4/3's shooter I can clearly see the increased colour and tonality from a full frame sensor, the pictures have more depth to them. Now to some this won't matter but to me it's something I enjoy seeing and it's hard to give up. That doesn't make smaller sensors bad, they're very capable, it's just personal choice based on what I see. I gave up the Canon 5D2 because it was too bulky and heavy, the A7 is a bit smaller and lighter than the E-M1 so it works for me a lot better. Carrying the A7 and a few lenses is no chore, as long as you keep them at shorter focal lengths (which I do) and I get all the benefits of a FF sensor. There are times when an m4/3's sensor can win in certain scenario's, but they are not that often for me and what I shoot. That's how it's panned out for me anyway, I'm sure I'm not alone in that view. M4/3's is great for telephoto stuff in a lightweight package, nearly everything else is a win for FF for me.
 
Whilst I love my Olympus OMD EM5, I have become a little dissatisfied by the noise level and DOF control. I really enjoy using MF lenses and find my Voightlander 25mm f 0.95 is almost permantly attached to my camera but mostly I stop it down to around f1.4 as it is really soft wider than this. I'm considering selling a couple of lenses I rarely use and dipping my toe into Sony Full Frame territory but could probably only afford an A7 (first version). I would probably pair it with a Voightlander 40mm f1.4 or similar and think I'd be happy just using this combo for several months and just pull out the Olympus if I feel like shooting some other focal length.

I'd like to ask any forum members that have experience of the two systems if they have been happy with or regretted similar changes and why? I'm primarily an enthusiast and used to take lots of travel shots from around the world but since I have had kids I mostly take photos of my family now. Whilst the Olympus does a wonderful job for this, I can't help but be critical of my own shots and would really love to explore the additional creative freedom that FF would offer.
I use both M4/3 (Panasonic GX7) and Sony A7 and A7s.

I find that I am happy to use the A7 at ISO 12800 as maximum with auto ISO, the GX7 I don't like going over ISO 3200 though I have auto ISO set to 6400 now out of necessity.

I am spoiled though with the A7s and that is my low light and video camera of choice.

In good light the A7 is the best though all three have their strengths and weaknesses.

I also use a mix of lenses with the A7s/A7 including some native (if you DO get an A7, save for the Sony Zeiss 55 1.8).....but a lot of Canon EF lenses.

There are adapters now that allow the Canon lenses to be used on BOTH M4/3 and E mount so I can use one lot of lenses with double duty (was triple duty before I sold my Canon 7D).

Generally, I much prefer the A7/A7s and the GX7 is more a secondary system now for me but since getting the kipon EF to M4/3 AF adapter I have had some fun with the GX7 again.

The GX7 has EV -4 AF unlike the A7 but while it has that low light focus, it is not a camera I want to USE in low light.

The A7 only auto focuses to EV 0 but that is still quite low light and lower you can always use manual focus.
Addendum: 1" and m43 are closer than m43 and FF. It's more than a stop of performance across the sensors. You can't overcome the resolution, color, and dynamic range with a stop of light. I use both systems everyday day and it's not close for me around the home.
That's the APS-C m43 argument. Only about 2/3rds of a stop difference in theory and in some cases less than 1/3rd of a stop in real life. Hardly a worthwhile difference. But lenses or 5 axis IS, or handling or 4K video, or simply size or price, are easily better reasons. Even feature set or higher FPS would be a better reason for some.
If you are wondering what the difference is, between m43 and FF - any FF system - for stated objectives of low light and subject isolation, your inclination is correct. FF is noticeably better in all łight to my wee little eyes and in poor light it's not even worth comparing.
I've seen micro four thirds beat too many FF cameras in challenges and micro four thirds cameras named camera of the year over larger systems by every site from DPReview to professional photographers with blogs. Each systems has its advantage. The Nikon one is the top dog for focusing with DSLRs lenses, and Medium format still has better IQ and easier subject isolation than FF.

I bought in to NEX because I thought it would make for high IQ pocketable system. That did n't happen, but Micro four thirds with the GM5 and other bodies appear to have achieved it. On the other hand Sony has made some good size (but nowhere near pocketable) FF cameras with 5 axis IS that are attracting a lot of competing FF owners.

And if you are into video, the only affordable 4K ILCs are Panasonic and Samsung.
