In Topic: Introducing Nauticamís WACP - The Wide Angle Corrector Port: Discuss Here

we've discussed just recently the nikonos 13. I sure as s**t am not selling it but i sure as S**t want this thing also hahaha

 

I love the compactness and IQ of the 13mm so its not going anywhere, but the versatility of this lens also is highly appealing.

Hey Geo. 

 

The shallower DOF I was referring to is a characteristic of the nikonos. It has a shallower DOF than a normal fisheye so on a high res FF body (which has narrower DOF than cropped sensor) the focus will need to be even more spot on

I have the rs 13, and I believe Adam does as well. Its spectacular. I've not actually used any other lens, wide or macro, since i had it converted. I love it on both apsc and full frame but i've not gotten to use it enough to have a firm opinion on which format I prefer it. The DOF is far shallower than a normal fisheye. This can present a problem on a high res full frame body and that is an issue i have noticed but its easy enough to work around. The only 'complaint' with the 13mm is the fact that it cant be used for splits. The sharpness and 'look' of the images from the RS imo is far superior to any other option i've used (not having used the Nauticam WAP converter). 

 

Tangent aside, I am very much looking forward to using the RS on the d850 but I am curious as to how the much higher res + already shallower than normal DOF of the lens will perform

There are people far more qualified than I to speak on this issue but:

 

I shot the d500 underwater for the first time this weekend. I usually shoot the d810. in terms of overall image quality, there is very little difference between the two at least underwater. Like Adam said, shooting through and under water will reduce many of the typical advantages of the d810 over the d500. If I were choosing now, id go d500 over d810 for underwater shooting.

 

The image sharpness may be slightly better on the D810, ISO performance in real world underwater looks nearly identical. I have to look at exif data if I really wanted to know which camera took which image. I prefer full frame usually for the narrower DOF, better high ISO, and wider FOV but underwater the former two don't seem to give any advantage to the d810 vs the d500 (d5 and d4 are a different story). The d850 may perform slightly better than the d810 but will need the highest quality lenses and ports as Adam mentioned. 


In Topic: Nikonos 13mm Appreciation Thread

sweet man! i've seen a few 20-35 floating around but heard the same thing in terms of it not being a useful focal length since its more like a 28-40 something? So I've not pulled the trigger.

 

But the 13mm...i love it. it was ridiculously expensive to buy/convert and I went broke, but now that im finished paying for it it was absolutely worth it!

 

I very much look forward to seeing your results from the solomons. I have some (hopefully) good stuff coming up including a return to guadalupe, and the 13mm probably won't leave my housing for any of it haha i preferred shooting wide angle before this lens and now i haven't been able to bring myself to put on a macro lens. unless i get the nikonos 50mm

 

I appreciate the response, i'm glad somebody answered haha
