#358210 Thoughts on a g7x set up...

Posted by Alex_Tattersall on 22 February 2015 - 10:06 PM

Hi Nick. I’d be a little wary of the G7X if I were you, it does not behave like most other compacts so needs some consideration. If you are thinking of going wide angle, the G7X is particular in that its lens is shorter when at its widest. The result of this is that if you screw a wide angle lens to the front of the standard port, you are left with a large air gap between the camera lens and the port glass with a result that the corners of the image become very soft and out of focus with heavy vignetting around the borders of the image. The alternative is to zoom in which then means you lose much of the benefit of the wide angle lens.

 

Nauticam have overcome this issue by offering interchangeable ports for this camera, a shorter port for wide angle and a longer port for macro. When you have the short port installed, you cannot zoom in beyond about 40mm as the lens extends and hits the glass. This does mean that you lose flexibility that you would normally expect with a compact camera but you do end up with good image quality for both wide angle and macro. As far as I’m aware, other manufacturers do not offer a similar solution.

 

We have sent a setup to a French magazine, Chercheurs d’Eau, who are currently running tests with the Nauticam, Isotta, Recsea and Ikelite housings for G7X with a variety of wide angle lenses so this will be worth watching.

If you are looking for flexibility to change from wide to macro underwater, I’d still personally think the Sony RX100 Mk2 is the winning choice for underwater. This camera though does not perform well underwater for white balancing and the flash recycle time tends to be longer than the Canon.

Nauticam also has a 140mm glass minidome for the mirrorless mount. 




#355391 D750 or D810 for underwater photography?

I was very pleased with the D750 in Raja Ampat last week, small and compact, excellent image quality. Giving up my D7100 now.




#355330 140mm minidome on Nikon D750 FX format

Posted by Alex_Tattersall on 11 December 2014 - 08:31 PM

Hello all,
 
I’ve just come back from an Alex Mustard workshop in Raja Ampat where I was predominately using a 140mm minidome on the D750. I was using it with the Sigma 15mm and sometimes with the 1.4x Kenko teleconvertor. I have to say that it has changed the way I think about FX underwater as I love the practicality of minidomes but did not want to compromise on quality. I am very pleased with the corner sharpness of the 140mm even up to F7.1 with the Sigma 15mm. Here are some images taken with the minidome.

I hope you enjoy seeing them even half as much as I did taking them.

Where are you based? You can bring it to us and we can have a look at it with some different cables for you. We are in Bournemouth. Did you buy it in the UK?

The new Saga holders fit the SMC with the SMC adapter it comes with. The only problem I found was the unused diopter getting in the way of the strobe but apart from that, fliptastic :)

The Nauticam system has been tested with a full battery and will give approx 1000 hours of constant green light on a full battery.

#345224 Nauticam SMC in Puerto Galera

Posted by Alex_Tattersall on 29 March 2014 - 01:25 AM

With the 7D, I’d turn off the half-shutter press off so you are focusing on the rear button, find a suitable subject, no current or swell, and a place where you can put a sand spike to rest the housing on. Use the rear lever to focus to the magnification you want approx then release. Using the sand spike, gradually ease the housing forwards and backwards until you see the subject in focus and then pull the shutter. Take lots of shots as the DoF is very minimal especially as you increase to 1:1 on the lens. Think about the out of focus areas and how they will appear in the image. Breathe and work within depths that you are very comfortable with. Spend 30 minutes with a subject.

Posted by Alex_Tattersall on 19 March 2014 - 10:15 PM

Hello all,
 
Just returned from a Photo workshop I was running in the Philippines. I didn’t take the 105mm macro off my D7100 for 9 days. Here are some results with the outrageously strong and sharp Nauticam SMC. Mostly uncropped.

Karen,

 

Just screw the Subsee +10 to the front of the macro port you are using with the 12-50mm, you’ll get good results with that combination.
