In Topic: Advice on the Sigma 150mm 2.8

09 April 2014 - 02:21 AM

I've done eight dives with OS version on my Canon 7D and I like it a lot.  It is much longer, heavier and the auto focus is a little slower than my Canon 100 .macro.  The minimum focus distance is only approximately 40mm/1.6in more than the Canon 100.  Shooting super macro with a Subsee +5 yields around the same 2:1 that I get with the Subsee +10 on my 100 macro but with double the working distance, so it is much easier to use for this type of photography.  Using a Subsee +10 on the 150 will get you around 3:1 magnification but is an exercise in frustration as this is very difficult to achieve unless you are shooting in very still water and have the camera held very steady.  I find it is a great lens for small fish that don't like you getting too close and it will be my go to lens for dedicated super macro photography.

In Topic: Paper choices and you

18 March 2014 - 01:09 PM

Steve,

 

Go with the metallic paper Bill suggested, results for underwater images look stunning on this type of paper.  I run a small photo printing business from home as a sideline using an Epson Stylus Pro 9900 and once my customers see their images printed on metallic paper they won't settle for anything else.  I started out using the Red River Polar Pearl Metallic but couldn't purchase it in rolls in Australia and switched to the very similar Chromajet Metallic Pearl.

 

I've also used the Red River Polar Pearl Metallic with the same printer as yours (Epson R1900) and the results were also excellent.


In Topic: Which Eneloops to use with ys-110a...2000mAh or 2500mAh?

12 March 2014 - 03:07 PM

Do you really need the extra capacity of 2500mAh?  I looked into the 2500mAh version when they first came out.  Sanyo are claiming on 500 life cycles (ie charging cycles) for the 2500mAh version versus 1800 for the 2000mAh version.  The 2000mAh version had more than enough capacity for three to four dives a day with my Inon Z240 so I figured why pay more for capacity I didn't need and much lower overall battery life based on how many times they can be charged.


In Topic: Sony 30mm macro lens + wet Inon lenses, why it dosen't work?

I am thinking about taking pictures like wild textures, and for that purpose I am looking for high magnification. Did you ever try to use teleconverter and wet diopters?? 

 

Yes, but that was with lower power close up lenses than the Subsee +10 I use now.  I get all the magnification I need with the Subsee by itself with the Canon 100 macro.

 

 

 

I see that You have Tokina 35 macro lens. Did you found that lens useful for macro?

Not good at all for small stuff, great for reasonably sized fish.  I rarely use it these days.

1.4x teleconverter gives a 40% increase in magnification and 2x gives 100% increase in magnification.  Main downside is that functionality of auto focus decreases with increasing strength of teleconverter.  With 1.4x autofocus is noticeably slower and with 2x autofocus is virtually unuseable.  I rarely use teleconverters these days and usually use wet close up lenses.
