In Topic: Ikelite battery capacity NiMH for DS 125/160/161

15 April 2015 - 02:12 AM

If your looking at getting new battery packs I suggest the Ikelite Li-Ion packs as they are lighter, quicker to recycle, and hold more charge.  The are 3900mAh.  The only downside are they take longer to recharge when flat and you have to buy a new recharger as the older Ikelite chargers dont recharge the Li-Ion.

In Topic: Wide Angle Question Tokina 10-17 vs. 11-16mm?

15 April 2015 - 02:03 AM

I have both the Tokina 11-16mm and the Tokina 10-17mm FE. The Tokina is a awesome land lens but I never take it underwater as its basically not wide enough in the angle of view.  The Tokina 11-16mm has 104-84 degree view compared to the Tokina 10-17mm with 180-100 degree view.  I shot big animals up close and have my Tokina 10-17mm in my housing without gears set on 10mm (180degree) so I can fit all the animal/scene in and be close enough to light up the subject with my strobes.  You will find that the narrow angle of view such as which you have with the 10-24mm Nikon and Tokina 11-16mm you simply have to shoot your subject from a much greater distance and having reduced impact from strobes or trying to frame parts of larger animals like head portraits. The Tokina 11-16mm since its rectangular might be a lens to play with if your shooting under/overs or need straight lines like on wrecks where a Fisheye might be too curvey.

In Topic: which macro lens for a d7100 in an aquatica housing

thx, but the tokina seems to have quite a lenght when focus is at the max.


can i just get some some extension rings and add them to the flatport of a housing?

does this work like i imagine?


Yes the Tokina 100mm has a much longer barrel length when fully extended, which is similar to the older Nikon 105mm AFD which I use to have.  When I had the Nikon 105mm AFD I just added extra extension ring to the AF Macro port.  I havnt heard much about people using the Tokina 100mm underwater and I do not have one myself but I think it might be something to look into as it gets great reviews and is priced a fraction of what the Nikon 105mm VR lens is. You would come close in buying the Nikon 60mm AFD and the Kenko 1.4x TC and the Tokina 100mm for the same price as a brand new Nikon 105mm VR..........

As other have stated it depends on where and what your shooting, but for a first macro lens the 60mm to me is the best starting point. There are two Nikkor 60mm the older AFD and the newer AFS.  I prefer the older AFD version because 1. its cheaper and 2. you can add a Teleconverter like the Kenko pro 300 1.4x. The downside is that the AFD is a fraction of a second slower to focus compared to the AFS but the AFS does not work with the Kenko TC in AF.


Adding the Kenko 1.4x TC to the Nikkor 60mm AFD turns it into a 85mm with a 1.4x image size which makes it a very versatile combo and is my favourite macro setup. To the point which I sold my 105mm due to lack of use.  The Kenko 1.4x TC is also reasonably cheap around the $160 and you can also use it on other lenses like with the Tokina 10-17mm for CFWA.


I would start off with the 60mm and Kenko first and master that before going for something like the 105mm.  But when you do look at a longer lens also have a look at the Tokina 100mm Macro as it gets  excellent reviews and its a fraction of the price of the Nikkor 105mm.


Hope this helps,
