In Topic: NEX Macro Option?

19 February 2015 - 05:19 PM

I have one time mistakenly took 50 f1.8 as the 30 macro and used it with Subsee 10+

The results were stunning

Macro lens options for e mount cameras include

30mm macro

50mm f2.8 Touit

Sony 90 mm f2.8 G


Forgot to mention,  I also have

1. add on dry close up lenses with 49mm, 67mm and 77 mm threads

2. Kenko close up extension tubes for Nex

3 A number of wet close up lenses

I also have limited experience wht A7 on land ,....which I sold soon and replaced it with an A7r. I have strong doubt in their capabilities of being an underwater shooting gear...Slow AF really hurts and limited lens availability is another issue.


In Topic: D750 or D810 for underwater photography?

14 November 2014 - 08:32 AM

As the owner of a D800, I have been looking for a housing for it...for a few years and now I have come across two D750. The two D750s look like present from heaven for underwater shooting

 

Well I almost forgot there is this D750

 

To me D810 is THE camera for shooting underwater, if you don't mind  its weight and price. The 36MP sensor is simply too important for macros...and the cropped 15MP...for longer reach as well

 

However, D750 still makes great images with fast AF..and faster fps...which is sometimes needed in moving So to me both are great and I tend to choose D810..since the investment in housing is the same

1. Never think of bringing 18-200 down. Even on land, this lens is sloooooooooooooow in focusing.

2. A dedicated macro lens plus/minus a closeup adapter is the best solution. Be sure you bring a video torch for lighting. Currently Sony 30mm macro will do the job. A Zeiss version of 50mm selling around 1K will also be good.

3. Nauticam offers the best housing. The cost is high but the it is well justified by the depth, ergonomics, availability of ports and good after sale service. If you buy the Meikon housing, you will sooner or later know its limitations.

4. The advantages of Meikon housing

a. good price, incredibly low

b. light weight

c. good resistance to water...my 5n Meikon did not get any leak at 40m

It also suffers from several weaknesses

a. The buttons cannot resist water beyond 19m (my experience)

b. Lack of zoom gear

c. Lack of port supporting various lenses.

 

Obviously Meikon is selling this housing to other water/outdoor sports rather than scuba diving

The rated 40m is also an obvious weakness because I have seen various plastic housings leaked at 40m


In Topic: which lens for sony nex 5n for sharks?

16mm for sure, and an adapter for UW at 11mm is a welcome addition.


There is this super wide angle adapter for 16mm, much like the fisheye one. Make sure it works. If you want versatitliy, make sure 16-70 can be placeble. I would think of a dedicated port from Nauticam with zoom gear will fit it.
