Nikon D750 & D780

Confused it's been a long week and a few beers - how many shots on RAW should I be able to get onto a 16gb card? Camera says 288 but my head says it should be more? Thanks in advance

When you put the card in the initial guesstimation of number of shots available is way off, usually about half. On my 32gb cards it says around 560 IIRC but I get over 1000. Don't know why this is, the only reason I can think of is that it's to do with the lossless compression. Why it doesn't factor this in initially I don't know.

OK so on aperture priority it does change the curve ;) I find this very bizarre as all priority mode did was decrease ISO 2/3 stop for ADL, exactly the same as I did with manual. I tried manual again and it doesn't affect the curve (just the exposure). Most odd as A priority is (in theory) doing nothing different to shooting in manual accept changing the ISO for me (in this example). Seems like there's some voodoo magic going off which is turned off in manual mode for some reason ;)

... that's exactly why I don't use ADL. I don't need unpredictable magic interfering with my pics.

Anyone here own the Sigma 85mm f1.4 portrait lens...? I've just found these amazing images shot with it, worth viewing, sublime;

http://www.juzaphoto.com/recensione.php?l=en&t=sigma_85_f1-4

I need this lens.

Have you been following my posts of late :p I love the rendering of this lens which is why I'm persevering to find one that works with my camera. Reading around it appears that a number of the newer Nikon bodies can be hit and miss with 3rd party lenses. Looks like I've got one that's more miss than hit :(

@Sir SR has/had one. There are rumours of an art version being released soon.

I really rated the lens and it'll be interesting how much the art can actually improve on it. I'm guessing not much, more to complete the range.

I think you'll find it will be alot sharper.

It was very sharp anyway.

The Arts are in a different league though. The original Sigma's were a little smeary wide open.

Again, having done some extending reading on this a large consensus struggle to see how the Art will be much better as many believe that the 85mm was kind of the start of the Art line just not badged as an Art. Take this with a pinch of salt though as it's consensus gained from the t'interweb and we know how accurate that can be ;)

My feelings on this (based on not a lot ;)) is that sharpness won't be that much better, but the Art will have better coatings leading to better colours, better contrast (giving the perception of improved sharpness) and less flare. I would hope that CA's will be better controlled to as they're pretty bad on the current model (but to be fair this is true of most fast primes). The reason I've not waited for the Art is cost (would imagine it's going to be at leat £200 more than the current lens) and weight. The 50mm Art is 815g so I'd imagine the 85mm Art is going to be close to 1kg :eek:

I had the canon 85 1.2 afterwards and now the Nikon 1.4G and I'd be very picky to spot a difference in sharpness, mine was tack sharp. It's the only siggy lens I had that I rated.
 
Do you think we'll see a Nikon DSLR with decent liveview any time soon? I still can't my head around why it's so shoddy, current mirrorless cameras have shown how good contrast AF can be. I can't decide whether it's cost (having two 'high end' AF systems might make bodies too expensive, although the Sony a6000 isn't expensive and has one of the best CDAF systems), pure laziness, or as I've seen stated online somewhere that the current lens line up isn't adapted to work quickly/efficiently with CDAF.

Having just looked at scores I've got a feeling that you will be right god dammit ;) :p Depending on systems of course ;)

Looking at the 85mm vs 50mm Art on the D750 the Art is noticeably sharper, 20% sharper by my calculations (20 vs 24)
Screen%20Shot%202016-06-18%20at%2008.34.22_zpsroi0bnsf.png





But the D810 shows the true potential difference, a whopping 48% sharper :eek: (23 vs 34)

Screen%20Shot%202016-06-18%20at%2008.34.48_zpsxhu0rtbq.png




I would expect the 85mm Art to be on par with the 50mm Art.

After the Fuji XT1 live view was a big disappointment on the D750, Still a fantastic camera though.
 
I have seen some images on here from the sigma 85 f1.4 and Nikon 85 f1.8g which I couldn't really imagine any sharper! Maybe it's because I don't pixel peep any but my own images lol
 
My D750 completely froze this morning, I was in between shots and went to change aperture and nothing would change, turned camera off but nothing happened still on and frozen. I tried opening menu, previewing shots but still remained frozen, only when I removed the battery and reinserted did it unfreeze. Anyone had this happen, hope it's not the start of a problem.

It's a known issue, happens on some cameras and not on others. Some people believe it's linked to the type of SD card used, but I'm not so sure as it seems to happen with different cards. It happens on my camera every now and again. Frustrating when it happens, but have learnt that as soon as it appears to do this to not faff and just quickly turn off, pop the battery out, replace battery and turn on again. Takes less than 5s, but of course this can be the difference of getting a shot and missing a shot. I was hoping Nikon would fix it via a firmware update but so far there have been two updates and no fix.
 
I am using the Samsung Pro 64GB cards in both my D750s - they have proven to be reliable and more than fast enough for how I work.

On Canon, I had the sigma 85 1.4 and the only things that need improving were CA and focus reliability / repeatability. I had / have the sigma 35 1.4A and this has always been bang on reliable on both canon/nikon. I have tested it against both the canon 35 1.4 v1 and the nikon 35 1.4g and found the sigma to be way better in rendering and sharpness.

Some nice shots in there for sure.
But it's not just the lens.
The light, and the person behind the camera is the biggest factor by far.

And the processing ;)
 
Well my new Sigma 85mm has arrived and has exactly the same issue as the previous one. I'm going to have to give up on Sigma for now either until I buy one that's compatible with the dock and hope that solves the issue, wait until I upgrade my body and see if that works better with them, wait until I eventually send my camera in for the shutter issue and ask them to check the AV module whilst I'm in. I'm not sure the latter will solve it though as it's only Sigma lenses that have this phenomenon to date so it would appear that for whatever reason my particular D750 doesn't like Sigma.

I could use the and just not use the outer two rows of AF points and have to focus/recompose more, in fact I know a number of portrait togs (and maybe other types of tog) that only ever use the centre point. I know it's not the end of the world not being able to use the outer two rows, but it just seems a lot of money to then have to make allowances for. It's not as though the outer points are just slightly soft when the centre point is bob on, they are way off. Maybe a lot of portrait lenses are like this but folk don't use the outer points and so never noticed :lol: ;)

I think I'll just stick to using my 70-200mm for portraits for now.

I am doing that too :)

Yeah, it's a shame as the Sigma's really nice. It's so nice I was half tempted to settle for sticking to use the central focus points tbh as I do tend to focus recompose myself a lot for static subjects as I prefer the centre point, it just doesn't settle well with me paying that kind of money for something that doesn't work as it should. Maybe it's the northerner in me wanting value for money all the time ;)

If nikon supplied you with a replacement whilst your camera is in for repairs/recalls then I'd have sent mine in a long time ago, I just can't bear to be without a camera :(

Sure it's not field curvature?

Yeah. If I focus recompose it's fine at the edges, if I use the next focus point next to the outer two it's fine. Will post some examples shortly.

Forgot to say that if I don't MA for the centre point the outer ones are sharp. I said I would post pics anyway so here they are, all focussed on the elephant.

Centre AF full frame plus 100% crop.

What aperture?
 
twist said:
So stop it down to 2.8 and see what happens.
Click to expand...
Why? I bought this lens to use at f1.4. It clearly can use the outer points to focus sharply as it does so with 0 MA, but then the centre point is as bad as the right one in this example. So I can MA the lens to have the centre point sharp but the outer ones way off, or don't MA it and have the outer ones sharp and the centre way off. The other thing to point out that this had to be done via default MA as adjusting via the 'normal' lens specific MA it doesn't adjust enough, even at +20. Default MA 'only' needs +10 to correct it.

Obviously if I'm missing the point (wouldn't be the first time ;)) and you're trying to show me that this is normal then please say as I just expect all AF points to pretty much match, except the variables due to lack of edge sharpness and cross type vs line sensors.

Edit: just noticed that you've edited your post above. Won't that just 'mask' the issue though by having a larger DOF?

Just tried it f2.8, pretty much the same result.

Also you may recall I tried it with my 70-200 f2.8 and they're all Bob on even with +12 MA

No what I was pointing out was that perhaps your cameras outer points suck and your 2.8 lens masks that, hence the test. If the sigma still sucks at 2.8 it kind of eliminates the af module.

Ahh right, I see. Thanks for your help.

I think I'm still going to send my camera in anyway just to get it checked out, it's due a shutter recall anyway and it's approaching 44k actuations so not a bad time to send it in ;) I'm thinking if they can fix the AF so it doesn't generally front focus anymore then by not having to MA the sigma lenses by such extremes then maybe the AF points will be more consistent. I'll also ask them why lens specific MA doesn't work on Sigma (well it moves a tiny fraction from 0 to +20) yet default makes much more of a change.

I really don't like the thought of being cameraless though (n) Does being an NPU member make any difference to turnaround times, or is that just NPS?
 
Just got my NPU paperwork and it says that you get access to a "Dedicated professional website" but when you type in the web address it just takes you to the general UK nikon website pro tab which has very little on it except telling you the benefits of NPU and how to join :rolleyes: :lol:
