Advice on the Sigma 150mm 2.8

03 April 2014 - 09:01 AM

I have plenty of experience with the 105 VR macro qnd +5 and +10 diopters but have used the Sigma lens infrequently. What can anyone tell me about how the rig handles underwater compared to the 105 and their experiences and results using it.

I am diving mostly muck stuff in Dumagette the first week Moaboal the second. I have a D-300 with dual z-240 strobes in Seatool housing.

Regards,

Tom

Sigma 150MM macro F2.8-Any experiences/pictures out there?

16 November 2013 - 10:38 AM

After many trials i have concluded that I simply cannot house my Af-105-VR in my particular port/ housing setup because and extension of the lens means I must switch to a multi-piece port that the AF 105 wont fit in. However, unlike the 105 I can simply remove the limiting switch on the Sigma 150 and it will fit.

 

The result is that I am going to give the Sigma another try in Wakatobi in February.

 

On my first try it did not seem that the 150 mm gave me much more working distance over the 105 because the lens is longer. Therefore, using a subsee, the 105 seemed superior. However, I only spent 1 day with the rig. Any other experiences out there?

 

In addition an opinion was previously posted that whereas at 1:1 the 150 does not give more magnification than the 105, at less than 1:1 it will. Any experience with that?

 

Regards,

 

Tom

Has anyone tried this lens underwater. It provides 1:1 at about 10" working distance. It looks like I could add a diopter and still have adaquate working distance.
