Upgrading Equiptment...

MythicalSnapshots said:
Hey everyone,

So I have recently upgraded from Nikon D3500 to full frame Nikon D750.

I obviously already had lenses for my DX format but I am wondering if I should be buying all new or if some would be suitable to keep and use with my new camera.

For instance I currently have a 35mm dx format lens that will work on my new FX camera but I am wondering if I should be buying a 50mm FX lens instead? Obviously the 50mm FX lens will be full frame so be better for low light I assume as it will use all of the sensor but not necessarily be any better in quality is that right?

Can anyone offer me any advice on this topic?

Kind Regards

Joe

Dont upgrade untill all aspects have been thought through. In many cases upgrading can be considered a system change and lenses deffinitely drives costs up
 
I'd imagine that a lens designed for a crop sensor would show very noticeable vignetting on a full frame sensor body. Never tried it but the image circle must be smaller by design or what would be the point, complexity and economic sense in making a range for crop and a range for full-frame?
 
I know nothing about Nikon gear but will DX lenses actually fit an FX camera?
I only ask because when I shot Canon I understood that Canon EF ( full frame lenses) would fit a crop camera but EF-S ( crop lenses) would not work on FF due to the mirror striking the back of the lens.

The thing with Canon lenses is that a EF-S lens will not physically fit on the EF mount. Mirrors hitting things is not relevant.

For Nikon, the DX lenses will fit FX cameras but the camera (at least modern ones, not my old film Nikons) will sense the lens and only record a cropped image.
 
You should change all electronically coupled DX lenses, otherwise you might as well have stuck with your DX camera.
 
The 35mm will work in full frame mode but will show heavy vignetting at closer focus lengths.
All DX lenses will work, but the camera will be in DX mode making it completely pointless having a full frame camera.

That's right. But my advice is to buy lenses that serve a particular purpose. I haven't owned a "standard lens" in decades, and I own very few prime lenses... I'm not saying you shouldn't; but IDKW the standard 50mm prime would be the first lens you would choose (other than it being cheap).
 
all dx lens's will work on fx but your only using the middle of the sensor
you would be best to start buying fx lens's or its pointless moving to the bigger sensor as your not getting the benefit
 
You can use virtually any Nikon lens with the D750 - the list is long and varied.

You can also set the camera to autometically switch to DX crop mode when you mount a DX lens (Page 111 of the manual). The DX image circle is larger than the area of the sensor used in DX mode (Page 110 of the manual) but you might notice some vignetting but nothing drastic (in my experience).
 
If the D750 is auto correcting to a DX crop you wont see much difference but you won’t be using the full sensor and the benefits it brings. If it’s not auto correctly you should see varying degrees of vignette in the corners.

I also think it depends on the lens, focal length and aperture. The website below explains it well with examples.

If anyone is thinking of moving from DX to full frame I’d always recommend updating your lenses from DX lenses to full frame lenses before you get a full frame camera. full frame lenses can work well on a DX camera until you move to a full frame. Once you get a full frame camera you get the full benefit the sensor provides straight away.

Yes they do fit

I have already upgraded and all aspects were thought through... thanks for the help.

It uses only the middle section of the sensor instead of the full thing. But yes it does show vignetting but obviously that can be corrected in post.

I already have a couple of other lenses for other uses, the 50mm would be used for full body portrait work potentially.
 
Using a DX lens on the D750 will put it into DX mode giving you a 10mp image. If that’s enough then fine but it doesn’t give you that much scope to crop. Also as you are cropping the image using DX mode it will accentuate noise.

Thank you I didn't know this about the noise which is what I was hoping to find out

No, he can shoot it fx with lots of vignetting.

Any time you crop into an image then noise will be more apparent as you are ‘enlarging’ it. This will of course depend on light, ISO and how much you crop into an image.

Well yes but who would really do that? You’d either use DX mode or crop it out in post, either way it’ll enlarge the noise and make it more apparent.

Someone who likes vignette, in some cases its okay with tinkering, as said, I'd just sell it and buy the 50, they're like 60-70 used.

Yeah I am aware of that but if thats the case surely using a DX lens on either camera body would have the same amount of noise? As isn't the "crop" the same eg it behaves like 1.5 x the focal length on the dx body?

About £140 for a good used one from a store these days, for the f1.8G anyway.

When I tried a DX lens on FX it was more than just vignetting, it was a completely black circle :eek:

I never meant the G.

You’ll probably find the D750 in DX mode still has less noise than the D3500 tbh (at normal viewing size) as the pixels are physically larger.
 
twist said:
I think its pretty decent and it's cheap and it's better than a 35dx on a fx.

Probably is better, and it is cheap. I was a big fan of the G though, lovely rendering.

Okay awesome thank you.

SO by the sounds of it, I can keep using my 35mm in DX mode as a 50mm on my FX body. But look to replace that soon.

I also have a 50mm DX which I may do the same with. Then I have a 10-20mm DC Sigma lens which will be the first lens I look to replace for full frame as that will be the one that is unusable.

Both Nikon 50 1.8 d and g are full frame

Everyone has their own opinions on this but my opinion is why buy a FF camera and not use the full sensor, at least for the majority of time? If you’re going to use DX lenses then you’d have been better sticking with a DX body getting the best out of both lens and body.

For what it’s worth the 35mm f1.8G on the D3400 gives you 10mpix sharpnes/detail, the 50mm f1.8D and 50mm f1.8G give you 19 and 17 mpix respectively on the D750. I would guess that the 35mm dx on the D750 will give you a max 10mpix, maybe less.

Sharpness isn’t everything but 10mpix isn’t great and certainly not getting the best out of FF.

Ah, I assumed when you said you had a 50 it was one of those.

Yeah likewise, I don’t think Nikon do a 50mm dx do they?
