#402228 RIP Dean Burman

Posted by Cerianthus on 06 January 2019 - 12:06 AM

Very sad and sudden news. I also enjoyed his conversations on wetpixel. I never met Dean in person but I bought a spot from him for the very first digigreen trip to Scapa. An amusing bit of conversation was my misinterpretation of his question are you well. I wish his family all the strength they need after this loss.

From the specs slighty faster and the same aperture at all focal lengths.

Am I the only one to think a planned bankruptcy is highly immoral? Just to ditch personnel that might have worked there for years and are no longer needed without a proper leave package, and shake off some debtors and save some cash.

I shaved part of the top off because I had it attached to something.

#384462 Canan 80d ikelite lens options

Posted by Cerianthus on 28 May 2017 - 06:35 AM

I am not familiar with the lens but if it is not a fisheye, you would want the larger dome. I am also unsure of how wide 18mm on a crop will be. I don't know how close you will get but 18mm rectangular is just not that wide.

Ive been on the day tour, using the tokina 10-17mm and my canon 70d for the underwater bit. I used my wife's 50d for topside. https://flickr.com/p...157657954221343

You had to share water time as only six were allowed in the water at one time but at least 3 days will give you more chance.

They did the repair, but they might be able to source a part for you. I found them very helpful.

#382094 Nauticam NA 5D IV housing with 8.5 Dom positive buoyancy

Posted by Cerianthus on 09 March 2017 - 05:51 AM

That is complete , Well you know. If it is too buoyant you either need a smaller port or weights. That doesn't change if your housing is made of gold or balsa wood.

#380650 Using Teleconverters on Full Frame

PS; if you read German (or dont mind google translate), an interesting test of converters is found on http://www.traumflie...er/overview.php

#380649 Using Teleconverters on Full Frame

Posted by Cerianthus on 15 January 2017 - 11:53 PM

If you need a teleconverter on all your lenses, would you not be better off shooting with a crop camera ?


My Kenko teleplus 1,4 converter has exactly the same type number as the tamron telconverter you are mentioning, so there might be something in it that they are the same. At my camera (canon70D)  the displayed f stop does take the converter to account. Also in the exif, the focal length is adapted. I think it is odd that the info is displayed and adjusted in my camera and not in yours.


when I use it with my f2.8 USM 100mm macro (not the L lens), I have to take care to avoid using microfocus adjust. for some reason, the camera will lock up (or just not release the shutter) if I use this combination (100mm, teleconverter + microadjust). If it is working, it is reasonably fast.


If you would use a teleconverter and a diopter together, you need a good focus light, or be probably better off prefocussing at 1:1 and shooting when the image is sharp in the viewfinder.


The canon teleconverters are really only aimed at the longer lenses, and wont work with wide angle and macro lenses (although they would match up nicely with your 70-200mm )

#379715 Mares fin bungee breakage

Posted by Cerianthus on 18 December 2016 - 08:52 AM

Sometimes stuff breaks. Get a bit of bungee for a few $$ and repair it... I dont really see the problem...For unbreakable, move to spring straps....
