In Topic: Sony A7 with 24-70 & Nik 15mm

Thank you Mark Twain...

When I start doing my research, a local dealer told me that I have to pay 1K just for the cabling. Apparently it is not. There is such an inexpensive flash cable connecting the hotshoe.

The A7 does not focus as fast as my other full frame DSLRs like D800/5D3. I have all those essential macro/wide lenses for the Nikon/Canon but as for A7, I have to wait for the newer wide/macro lenses. One way to get around is to use LAEA2/LAEA4 adapter to use old Sony/Minolta lenses. However, Nauticam housing does have space to accommodate the adapter.


I also have an A77 which I believe has image quality exactly same as your A65. Well if I shoot only in RAW, with two flash gun firing at ISO 50, I believe both have great quality.


1K just for cabling? That sounds way to much. Unfortunately I'm not well informed about flash possibilities on Nauticam housings as Ikelite delivers a all-round carefree package, but as far as I am concerned a dual sync cable in Nikonos' 5 pin style should not cost more than 200 € (with which you can use two Inon Z 240 I think which makes an ultra compact package).


Autofocus improved much with on-sensor phase detection but is still behind DSLR what I've heard so far. But with E-mount lenses I'm convinced that autofocus speed is more than sufficient for underwater and land usage)!


For Fisheye you could use the Nikonos wet fisheye lens, Nauticam has an adapter for it if I remember correctly. Macro is still an issue, I hope, Sony will release a decent macro lens within this year. Alternatively you can use the 28-70 kit lens with Nauticam's wet diopter in the meantime (sample images: http://nauticam.smug...161&k=CWXW5B3).


Maybe some lenses will fit into ports with the LA-EA2 adapter so you can use a macro lens (e.g. sony 100mm A-mount) but you need the exact dimensions to test this out.


A77 and A65 have the same sensor, nevertheless the A65 won't let you choose 50 ISO ;) IQ is great in my opinion (with ISO 1.600 maximum).

I went to Nauticam's website...and fail to find a system chart of all the necessary port/flash/cabling chart.


Regarding ports:


"A new port system was designed for this camera… the SLR port opening was too large, meaning that the housing would be too large, and the existing mirrorless system port opening is too small for some of the lenses expected in the new Sony FE lens lineup. So, a new line of intermediate size ports is required and is being delivered with this housing." (from the nauticam.com)


I guess here are the available ports for the A7: http://www.nauticam....list-b.asp?id=6


Regarding flash:


"The NA-A7 includes a pre-installed Nikonos style 5-pin bulkhead with universal hotshoe connection (x and ground connection only) installed, enabling manual control of the most commonly available strobes, such as the Inon Z-240 or Sea&Sea YS-D1. Additional strobe firing options will be announced at a later date." (from nauticam.com)

Zeiss 16-35/4 OSS announced: http://www.sonyalpha...m-f4-0-fe-lens/

Sounds quite interesting for underwater. I'm really sad that I bought an A65 when it came out and invested in Ikelite so that I have a complete setup (macro, wideangle, fisheye, 2 strobes, megadome, transport cases etc). If I had the money and no camera I would definately buy a A7 and use it in a nauticam housing:(


The A65 is not a bad camera but when I look at the weight, dimensions and image quality of the mirrorless cams of Sony... :o

Hi all,

what would be the ultimate lens bag for the Sony A57, given the fact that here in The Netherlands, we do a lot of macro photography. 

Your recommendations will be greatly appreciated!



I use the 60mm macro from tamron which is an outstanding lens. If you prefer a longer focal length you could also go for the 90mm Tamron without hesitation or for the Sony equivalent.

Zeiss 50mm macro officially launced today. Available for preorder from BH

Yep I will le tyou know how it goes. Had a fantastic write up at Reef photo

Thanks for the hint but I would like to know if my suggested setup would work ($1000 is also a lot of money for a 50mm macro)
