In Topic: classifieds search function is terrible

22 March 2017 - 01:53 PM

I am investigating this, but from a brief search, it looks like an Invasion problem that they plan to correct with a release later this year.

 

As a work around, searching the forums via Google works well. I searched "Wetpixel classifieds YS-D2":

I will keep you posted on whether I can fix the forum search in the interim too.

In Topic: Any hands on experience with Nikkor 20mm 2.8D ?

20 March 2017 - 12:53 AM

 

 

So far I've been suggested many things and all go in opposite directions. Some say that I may see the dome's hood on my photos and wood need to crop, others that I need the extension ring, etc. Which is why I came here for help. In other posts they mention this nikkor 20mm 2.8D but they didn't come to conclusions on the thread. 

 

Sadly, neither of these is actually the key potential problem. 

 

If you have a read of the article, the issue is actually they ability of the lens to have sufficient depth of field to allow you to have sharp corners. The curve of the virtual image caused by the dome mea that some lenses are simply not capable of maintaining focus on the center of the frame an the corners. This is not predictable unless you actually shoot the lens underwater with the dome and correct extension and see what happens. Some lenses are simply better than others (and these are often not the most expensive/high performance lenses...)

 

Unless someone has actually tested the lens, all bets are off (unless you are prepared to do so!)

 

All the best

Hi,

 

It was reviewed here;

 

http://wetpixel.com/...de-angle-lenses

 

It works OK behind  9" dome, at apertures of f10 or greater.

 

To be honest, you could probably buy a 170mm dome and a Sigma 15mm for the same amount as a 9"dome!

 

All the best

In Topic: Tentative gear selection...how am I doing?

Perhaps the most useful general lens underwater is a fisheye. I would recommend you get hold of a Tokina 10-17mm as soon as possible! Once you have, you probably won't use the 11-20mm much.

 

It will also work with a  small dome (which the 11-20mm will not).
