p.1 #1 · p.1 #1 · D750 DX mode vs D300


Tired of waiting for the mythical D400, I took the plunge to FX. From all the sample images, and from my own limited experience (had it 5 days) it looks like I'll have up to a 3 stop advantage at high ISO over the D300.

Because I wanted the same range as my 16-85 DX, I got the kit with the 24-120 FX. I already had the 70-300 VR and 105 micro VR in FX as well as my old nifty fifty from my D70 days.

My concern was resolution and reach because the D750 at DX is only 10 MP. I took shots from the 2 cameras and compared them using the same 16-85 at 50mm. The D750 was set for auto DX so that it became a DX machine as soon as I put the lens on it.

Because they metered differently and the light did change some, I applied a curve to the D300 shot to make the tonality similar. Other than that, they're SOOC, converted to jpeg. The D300 is at base ISO @200, while the D750 is at 100.

I couldn't see any difference when pixel peeping regarding resolution. I could tell that even at base ISO that the DR was better with less noise in the dark tones with the D750.

I feel I've got an improved DX camera over the D300 so that I still have the reach when I need it. And when I'm shooting FX, it's a whole different world. I do find the metering area cramped some, but the D300 wasn't much better....

I agree, the D750 looks slightly better IMHO

Looks pretty similar

I'm going to get a 750 (& get rid of my 610).

Did you use the articulated LCD? What do you think of it?

I'm also going to get a LX100 for fps (reach..)

Good luck with it

D750 sensor is better, so I'd expect an IQ advantage over the D300 despite the lower resolution (the D300 will still outresolve the D750 in DX, but everything else leans to the D750)

Frankly, the D750 shot is technically superior (Better DR), while the D300 shot looks better (more pleasing colour, exposure is correct where the sunlit areas on the D750 shot are hot).

You're giving up a small amount of resolution (generally the difference between 12MP and 10MP is not visible), some speed (vs a gripped D300) and the UI of the D300 in favour of FX, a generation newer sensor and 3 generations of processing improvements. If you don't need the speed of a gripped D300, this is a net win for most shooters.

Mawz, the intent was to be able to judge resolution, not exposure since I mentioned I had to apply a curve to the D300 image. Also, the light was changing, so the sun may have been stronger in one shot than in another. It's next to impossible with partly cloudy skies in the fall with a windblown sky to get 2 directly comparable exposures.From what I've seen, I agree with you that the D750 has noticebly better DR in any circumstance.

That said, I thought it would be more valuable to shoot woods, leaves, grass, and branches than shooting bricks.

Again, I agree with your conclusion that the D750 is a net win for most shooters, even those of us holdovers clutching our precious D300's.

Barrring any Nikon recalls, I'd say we have a classic in the makiing...

I concur, a net win for most ... until you consider cost

Well, with the D750 cost is much less of an issue if you're willing to shoot it in DX mode a fair bit, as it costs only a few hundred more than the D300s listed for. It's the D810 and that extra $1K where it really becomes insane.

Andre-- if you had been saving up for the replacement all these years, then you should be able to afford 2 D750's by now....

Don't forget that the AF system is going to be significantly better than the D300 as well.

You could have a D7100 with and end up with lots more resolution than the D750 in dx mode.

I wouldn't call it significantly better. It's the same basic sensor with some tweaks.

Depends on what you need. The D750 has a much deeper buffer than the D7100, especially in DX mode (where it should be notably deeper than a D300(s). It's also faster in DX mode (6.5fps vs 6) although the D7100 in 1.3 crop mode is even faster.

The main limitation in coming from a D300(s) to anything else is the combination of speed, pixel density and buffer depth. Nothing else offers all three. D7100 offers better pixel density at the cost of speed (small loss) and buffer depth (moderate loss). D750 costs speed when gripped (unwrapped also for D300s) and a small amount of resolution for a deeper buffer and better sensor.

Frankly, if you are looking at staying DX, the D7100 is the better choice, while the D750 is a solid transitional body when going from DX to FX since you can slow-roll the transition without really losing much from the D300 (unless of course you need the full gripped speed or the build).

Nikon doesn't really offer a DX replacement for the D300(s), or as good an FX upgrade as the D700 was (the D810 is close, but it's biased to resolution over speed, where the D300(s) and D700 were speed over resolution)

That might be a fine way to go if my D300 dies ... but it's not worth the $$ at all as an upgrade. I'm just not gaining enough.

That's not something I would say if I were shooting the D750 in full FX, but there are many reasons I have not switched to FX, cost being one of them, but size and weight being the other two.

A D7100 with a proper buffer would have fit the bill better.

Canon's 7D II makes a great stand in here, but one would have to be willing to juggle lenses .

It has been a while since I had the D300, but I think the D300 and D300s slows down significantly (fps) when in 14 bit RAW mode. Something to consider.

I moved from a D200 to a D600 which I often use in DX mode. What I find is that the D600 has noticeably better dynamic range at base ISO, and keeps far more detail in highlights with less tendency to burn them out. White balance is greatly improved as well.

What I have noticed is that FX images with a 28mm F1.8 lens are not as good as DX images with a 14-24mm F2.8 lens @ 18mm. The extra ~1 stop of DOF from DX is useful for my kind of shooting, which is basically close ups with micro lenses and wide angle lenses.

Ah, but he spent his savings on anti-depressants. I think he tried to charge them to Nikon, depression induced by non arrival of a D400 was the argument.

A penny saved is a penny earned

Why spend money on something that does not suit my needs ... my D300 is doing just fine.

It does (down to 2.5fps, the D7100's buffer full rate in 14bit lossless is actually faster than a D300's max performance in 14bit lossless), but it also gains almost no IQ benefits from 14 bit unlike the newer high-DR bodies, so there's no reason to select 14bit on the D300(s)
