Nikon D750 vs A7 : help!

Sony is expected to bring much improved AF performance to the next A7 cameras (4D focus, like on the A6000) - possibly a consideration but of no help now I know.
I wouldn't advice someone to take a decision based on the promise for this 4D focus.

I own the a6000 and I am not very happy with the AF performance. The burst is fast but the failure ratio is quite big also.

Sorry to say this, but at the end I did not see better results that when I was using the entry level Nikon d5100...(not a happy customer as you understand).

So, first wait for the real tests of thie feature and then decide.

That's why I am saying to try first.

His call is indeed touch
That's odd - I've found the AF on the A6K to be pretty good. Of course it depends on the lens, light, and scene.

What lens and (focus) settings are you using Dstillo?
 
AF Sensitivity: SONY wins (A7S AF -4EV / D750 AF -3EV / A7 AF 0EV)

ISO Performance: SONY wins (likely an easy win for the A7S)
I know you really want to write "SONY wins" but you do realize for the A7 body (and not the A7s) Sony actually doesn't win for either of those? That Nikon uses Sony sensors in the equivalent models (D610, D810 and likely D750) yet gets a little more out of them in terms of ISO and DR than the Sony A7/A7r? The difference borders on insignificant but it's enough to reverse the claim of "wins" -- unless you think the OP needs to buy both an A7 and A7s in which case he has to redo his price comparison as well.
 
Went to the shop and handled both the Nikon and A7 (both without batteries though). The a7 really felt nice, the Nikon is a lot heavier as expected but got a nice grip to it. Liked both. I might wait a bit and hope Sony releases an A7 with the a6000 af. It really amazed me how close the A7 was to my A6000 in both feel and weight, and it looked and felt very sturdy.

It didn't help much of course when the salesperson in the shop was over the moon with his A7 + primes, was considering to sell his 5D3+L lenses (like I did) and really was so enthusiastic about it, that he even offered me to borrow his A7 + primes for a day or two (happens he lives very close to where I live).
I often think of the cameras that way too:

Shooting Primes: A7 / Shooting AF Zooms: D700

and, as mentioned, the other way I think of them is:

Natural Light: A7 / Flash Photography D700

Long trips with lots of walking or hiking: A7 / shorter outings or events: D700

I'm in a different situation, but with some similarities - having both the A7 and D700 it's always a quandary deciding which lens line-up to invest in.

Again - good luck with a very difficult decision!

If you can live with nikons UI and liveview system+chimping, D750 is a better camera.
As has been said over and over, there is no 'better camera' when comparing two wildly different systems like the D750 vs. A7. Either you need the SLR configuration form and function (for any number of reasons) or you don't.

If you do, obviously the D750 will be better for you than mirrorless. If you don't, and depending on a myriad of other factors, the A7 may well be the better choice.
 
Looking for some unbiased opinions (yeah I know, difficult). Anyway, I'm thinking very much to get a FF camera to complement my A6000 and RX100M which I'll keep for those moments when weight or compactness matter.

But for all those other moments, and I do a wedding now and then and a lot of indoor work (kids, moving!!), I would get a FF camera. So compactness isn't exactly the most important thing. Things that DO matter in those situations though are AF speed, AF accuracy and lens selection. I'm currently debating between this:

Nikon D750 + 24-120/F4 (kit) + Nikkor 50mm/1.4 (total cost = € 2.799 + € 345 = € 3.144)

or

Sony A7(s) + 24-70/F4 + FE55mm/1.8 (total cost = € 2.299 + € 1.100 + € 899 = € 4.298)

So the Sony would cost me quite a bit more. Which one would you recommend, considering you know I also have an a6000 for weight/compactness (with some very good glass). Still a bit unsure about going to Nikon since I've been shooting Canon for all my life, but the deal I got for the D750 is really very good and the specs/reviews seem to point out that the Nikon could very well be the camera I'm looking for.

I think the A7s is a specialist camera.......more for video and REALLY low light.

Most weddings have some low light component but not at the level that the A7s AF is better.

In the "normal" wedding range the Nikon would be far better , actually I think the middle A7 would be better (than the a7s) too though still think the Nikon would suit you more.....unless you take your time and are not rushed.....great for nice old manual focus lenses.

The A7s would be a tremendous back up body for a wedding.

There are things favouring most cameras.......A7 AF is fine (to EV0) and flexible spot AF is very nice (could be handy for a wedding group shot with focus on a particular person or two).

I would be happy shooting a wedding with an A7 (I have done a few with much lesser cameras in the past as Friend/uncle ETC with camera type).

For paid wedding stuff I would go with Nikon or Canon .......there will be plenty using A7/A7s/A7R and lots of others though.

Enjoy whatever you decide.
 
If you take the A7 (s) you do not need the 55mm f/1.8

You can pump up the ISO instead.

The f/4 is enough. And you do not need that extreme swallow DOF in a wedding. f/4 in a full frame is swallow enough for almost all artistic ideas you may come up with. And usually even smaller apperture e.g. f/8 can do the work. Don't forget you will need some times to have everybody in focus.

So, if it is to go the A7 way, and specifically the (s), save your money.

Even sell your a6000. Having a second camera will not help you in this case. The 24-70 is all around. I use two cameras when I want one of the cameras to mount a good prime lens.
If you're doing a wedding, always always have a backup. When I help out my wife with family portraits she always has a second body that can use her lenses just in case there is a problem. Her mentor had his main camera poop out on him, luckily he had a backup on him. There is no redo's on the wedding so having two bodies is essential.
Mr. "eeper" is correct here.

I was thinking more as a friend acting as a second photographer in a wedding.

But if you have the responsibility for a wedding, yes, it's true that you need a second camera.

100% to have a backup

70% to use it concurrently at a different field of view (mm of lens) and have variety in your photos.

But in that case it's not only the camera that you need to backup, lights, batteries and even storage (double SD cards) are essential.

P.S. think about lighting where the wedding is taking place.

If you are going to use flashes, maybe the Nikon is better due to variety of compatible third party lighting equipment.

If you are only going with available light, then you need to consider a7s seriously. (the "s" model, not the others).

Ah, I wasn't thinking about that. In that case, both would be great, but since they already have an a6000 I would go after the a7s.

I think I set it correctly. It was a while back now - after a lot of attempts I gave up!

From memory I tried a number of different settings. Even tried the sports mode.

My issue was not that the a6000 didn't focus on something - it did - but it was always something else other than what I was aiming at!

Either the floor just in front - or a more higher contrast subject.

As I say in the end I abandoned the a6000 for action shots.

However my Nikon D750 arrived Saturday and I tested it out with the same subject ( my dog ) and in the same places. If anything now its winter the light was less and a more challenging situation for the camera.

I'm pleased to say I finally got the shots of my dog running and splashing like a nutter through streams! The Nikon D750 seems to really nail the shot and focus on the right thing.

Still had a few miss shots - but my success rate was probably 50% and this was a with a brand new camera I'm not at all familiar with.

With a bit of practice I'm sure I can get up to a 75% success rate.

Having said that is others are getting good success with the a6000 and small brown dogs running at speed that it does suggest its my incompetence - maybe the Nikon D750 is just easier to use.
 
Below is the short of shot that was very easy on the D750 but I found virtually impossible on the Sony a6000:

Nikon D750 - ISO 1800 - f8 1/1000 second - 240mm
Nikon D750 - ISO 1800 - f8 1/1000 second - 240mm



I'm sure a better photographer than me could do this on a Sony a6000 but the whole reason I bought the a6000 was to make this sort of shot easy!

Are you sure your dog is running?

Looks like flying to me :-)

Unless your place is out of D800, then a D800 at current street price less than that of a D750 will be a better choice.

Flash, 24-120G f4, and....a Sigma 50/1.4

A7, which I had for a short while, is a good general purpose camera when AF speed and accuracy is not required. Definitely A7 is not for wedding.
 
I wish I had the time and patience to read all the earlier posts. But I am expressing my opinion briefly to give you a longer-term view. If you have and love the Sony A6000 (which I do) the decision to buy any full-frame camera has the potential to disappoint but with the real opportunity to add enough creative gain to risk it.

That said, I decided on a longer-term strategy to buy the best glass for e-mount (inclusive of FE) in the belief that like legacy Leica lenses, they will outlive the bodies. IMHO mirrorless systems have sustainable advantage over dslr designs. I have given up my Nikon D700/D800 for a Sony A7S and A7R. I have replaced my heavy f2.8 zooms with Sony-Zeiss f4 zooms and primes. I have ordered the LOXIA 50mm and 35mm lenses as well as the FE1635f4 Z.

Many complain about the limited range and cost of the better Sony e-mount glass but if you can take a long-term perspective, you may conclude as I did that Sony is a better long term investment. And I love the interchangeability of lenses, batteries, flashes between the A6000 and the A7S/7R and the commonality of the menu system makes moving amongst these so much easier.

And by the way, I have no difficulty producing gratifying images for events such as weddings with all these cameras. You need multiple cameras for these shoots and having the extended range of features makes for a very flexible approach.

Finally, I think the A6000/1670Z is the best multi-purpose photographic I have ever used; miles ahead of my NEX-7… making my point that bodies come and go.
 
For the price of your A7 option, you can have your Nikon d750 with its kit lens, the 50mm 1.4g, and still add the Nikon 85mm 1.8g if you like portraits, and let's say the 35 1.8g, which should work perfectly. Hell, you could even get a used 5d MkIII and the excellent 24-70 f 2.8 for almost the same price as your A7 option ! Seriously, if bulkiness is not a serious issue, that's a no-brainer, except if you're seriously into the A7, which seems quite obvious, since you ask the question.

Anyway, whatever choice you make, I wish I could be in your shoes. Great cameras and great lenses !

Personally I think your ex-5DMKIII (+L lens(es) is the better all-around choice.

Good luck with whatever decision you make.

Exactly what I was talking about!!!

100% the same problem I am talking about!

My dog is of similar structure with the same way of running (flying). I managed to have sharp photos with the humble Nikon d5100 and I cannot with my Sony a6000's AF.

And I was trying closer photos. So that my dog is almost filling the frame.

I will try again but with only one point of focus and AF-S.

Maybe the traditional way is better and maybe the a6000 can actually do something.

But the well advertized AF-C cannot deliver. period.

I think single point focus would work fine with the a6000 - its AF is certainly fast enough. But you need to track yourself - no predictive tracking for multiple shots.

I think the original reason for my disappointment was the massive hype by Sony before and after initial launch of the a6000. It made it seem like you could pull out your camera - point and shot multiple shots of a high speed object coming towards you.

In reality as you say it just doesn't work as well as it the hype suggested.

Also interestingly the Nikon face detection works with dogs! I took a few portrait shots of my dog and left the D750 to figure out what to focus on - and it focussed perfectly on the dogs eyes.

In comparison I found the Sony a6000 seemed to not really even notice my dog let alone detect its face- too small and brown I guess!

Having said that the a6000 is a great camera and away from shooting moving objects I was quite happy with it.
