where there’s smoke there’s forum fire
Anyway I have been trying out different DX lenses on a D700 and most actually work not that bad, so I was wondering if you could get away with a 10% larger APS-C sensor for a 1.4 crop factor. This would allow higher MP with better ISO performance, right.
Wide angle lenses like my 16-85 clearly does not work on FX camera, but is there some extra room for that 10% increase. I know cost of sensor and other upgrades, but that aside do you think it could be done

For some people the vignetting would be a feature. I'd be interested in seeing a couple sample images of DX lenses on the D700. If those ones posted yesterday by nikonmonster were in FX mode, then the 35 1.8 has a bigger image circle than just DX.

I was thinking about that what I will do at work on a slow day I going to take some pictures with a D700 using different DX lenses, It would be interesting to see how they crop the image, I think on zooms I take on wide and one tele, all with the largest aperture to show the most edge problems

BTW where is Niko
That would be awesome if you could do it.
Yeah, it's weird to be second poster on some of these threads. It's usually Niko or alpha unless you're really quick on the response. Niko has gone MIA.

This might take a few days, We have been very busy the last few days,

No problem. I've got months until I'll even consider going FX. ;-)
Maybe it could work, but is a 1.4 crop factor really that much of a difference?
I guess your 12-24 would be slightly wider then, so it would make a big difference on the wide end, but not so much on the far end.
I think it's a great idea - would make my 10-24 as wide as the 14-24. How many MPs would the DX sensor (the current 12 versions) be if expanded for 1.4x - that is with the same density. I would expect ISO performance to also improve. My concern would be lenses like the 10-24 and 16-85, my current staples.
Here's what you can do to test the idea: Is it possible that you take the image in FX mode, and then crop the image 1.4x? Then it will be easy to look for imperfections.
Actually I like the DX crop the way it is. 1.5x is easy to multiply and divide by too. I don't want Nikon to go like Canon, with too many crops of sensors. I don't mind them adding a 1.2x crop to the D3S, I just don't want them to make a third sensor size.
Think about the problem with the 1D series. It doesn't accept Canon's "DX" or EFS (I think?) lenses, so it has to use full frame lenses. That means you can't get any super wideangles without starting another series of lenses, and would just make everything super-crazy.
I agree alphanikonrex, the 1.4x would have to work with current crop (no pun intended) of DX lenses. We don't need another lens line.

It is a app 10% gain so it would be app 13.5 MP, I am going to try a Sigma 10-20 and the 16-85 at work on the D700 to see how large the sensor app could be

I don't think that really matters and BTW it looks like we might see a 2.5 crop factor
Anyway I was just wondering what would be the ultimate D300s replacement, because a 1.4 crop 18MP would be certainly be better than a 1.6 crop
Pete
Does some one here have a Nikon 10 - 24 and a D700 to see app if this would work, because like Tedd said it has to work with current lenses, I think this lens would be the problem area

I think KR said it works from 18-24mm. Now let's not start a fight here ;^)
No it is not to see if it will actually work on a D700 but from a picture taken with the D700 you could properly measure to were app 1.4 crop would be add
Pete
And I don't think we are anywhere close to fighting, but you should try to minimize that KR thing
Well then let's just ask KR to test that for us ;^)
Yeah, I mention him too much.
I don't! I think everything he says is logical! Even if it's "BS" it's logical! Because sometimes having a sense of humor is being logical!
(If it goes on from here we should switch to PM)
OH NO KR?! NO COMMENT

Actually, the sensor would increase by 21% area, so about 14.6 MP.
I don't think it's a big enough difference to be worth it, frankly. People who really need the extra 1mm (equivalent) on the wide angle will get a D700 (or wait for Nikon to release a 9.33mm dx lens).
I'm guessing the potential issues of vignetting would also make such a camera somewhat unpopular, even if Nikon claims it's fully compatible. I know I'd be hesitant.
It's good to know I was missed :^)
I don't think a 1.4 sensor would work for Nikon. Look at Canon which already has 1.3,1.6,1 and the Canuts hate 1.3. They would have preferred the 1Dmk4 to have been full frame instead of 1.3. So I wouldn't be interested in a slightly larger/smaller (D300/D3) Nikon sensor.
Exactly. More Sensor Sizes = Plain Annoying
I have always thought 1.4 would be better and wondered why it wasn't made in the first place. If the curent DX lenses would work, I'm all for it. I only have one DX lens, the 18-200mm. As soon as NIkon announced FX, I sold my other DX lenses and will buy only FX. I know they cost more, but they will work on DX also. Lenses are something you keep longer then body's.
I'm with Pete and John (and Pete and Niko Re: KR). Why not get a bit more area if the lenses can handle it? Just because you don't use something doesn't mean it shouldn't be made. If it annoys you or you're afraid of it, you don't have to use it. That's logic. ;-)
