In Topic: D7000 or D800?

19 February 2012 - 12:02 PM

8" dome is great for fisheye on FX. Main benefits of bigger dome are for splits and rectilinear lens.



I would suggest buying the 16-35mm over the 14-24mm for underwater use. Reverse is true on land. But 16-35mm is better behind a dome IMO.

This image taken on FX in very dark conditions with available light only with the 16-35mm (using Zen 230 dome) and I think the corner performance is excellent.

I just ordered the 9in optical glass dome from Nauticam for their D800 housing (April I'm told) with a view to using firstly my 14 -24mm then (once I recover from the cost of the dome!) the 16 -35mm as you recommend. What are your thoughts on this domes use with these lenses.

Isnt it likely moire removal will be prioritised now the D800E is being released? Id take the Lightroom beta as a start, rather than the best we're going to see.

Video would be a whole other story of course.

Yes I agree,
I would like to hear what the medium format guys say about this since they don't use AA filters and the 36mp is in their territory now, admittedly not in the IQ180 league but treading on Mamiyas toes at 40mp even though the D800 pixel density is of course higher.
What camera lens combination was shown in the lightroom beta 4 example? 12mp perhaps?
I suppose we'll just have to wait for the likes of Ken Rockwells tests once he recieves his D800E now ordered

Roll on April!

PS I have now read the photo.net link and it was Canon 5D 12.8mp 24 -105mm zoom.

Imaging-resource.com tries to explain the difference between the D800 and D800e...

Thanks for the link, I found it somewhat comforting, but having digested it, I think I may be off the mark a little with my dome theory :(

I think the 16-35mm is a better performer underwater for FX (which is why I have one), than the 14-24mm. 14-24mm better on land.

Right - well its on the shopping list then! thanks again. Are Subal making (or have made) a dome specially for it as they did for the 14 24mm

I don't think that this is a camera to use with cheap lenses - apart from the Tokina - which is always pretty nasty - but we always tend to forgive it!
I used 70-200 and 16-35mm mainly - and both performed well. Although I doubt 36MP is going to look pixel perfect at 100% behind a dome. That said - it will probably look great down rezzed to a mere 24MP.

I agree absolutely and intend to use it with my Nikon 14 -24mm which until now has been stuck on my D90 above water and not exactly what it was designed for! I went for the D800E for precisely the dome reason you site as I feel there are plenty of AA properties in it already (so to speak) and therefore the prospect of a single ray of white light hitting only one of the RGB groups is even less likely.
It will still be fun to bolt the old Tokina 10-17 on to see what I get, like most everyone I love that lense and DXO takes the Chromatic Aberation out nicely.
This will be my first FX camera as it were, before we used to called them 35mm! back in my Pentax MX days.

Thanks for your insightful posts I always read them!
