#263905 Fiber optic snoot system for underwater strobes

Posted by zzz111 on 17 October 2010 - 10:03 PM in Lights, Strobes, and Lighting Technique

These are really coooooooool, thanks all for sharing.

Is it possible to add some glass at the tip, so that the beam width can be adjusted, like topside zoomable strobes?



#263903 Ikelite port/dome problem

Posted by zzz111 on 17 October 2010 - 09:35 PM in Digital SLRs/Housings

I really wouldn't advise this....you are putting a lot of load on the small screws than go into the front of the housing. I have just had to send my housing to ikelite as a stress fracture occurred at exactly this point and water started to slowly enter the housing.......you have been warned....



Agreed, I take it back. I do it at my own risk but it's really not something I should have recommended others to do.



#263832 Ikelite port/dome problem

Posted by zzz111 on 16 October 2010 - 09:12 PM in Digital SLRs/Housings

Thanks for the tips! The strap wrench worked like a charm.

And I'll be extra careful with the fisheye extension that's going on in it's place!


The fisheye port is actually easier to remove, just leave the port/dome on the housing facing up, and turn the dome slowly counter clockwise. The housing will stop it at certain position then you can turn the dome out. Be careful though, so far I haven't broken my housing doing that.



#245778 Macro in the Red Sea?

Posted by zzz111 on 24 March 2010 - 07:59 AM in Dive Destinations and Travel

Thanks guys! Then I'll leave the macro lens/ports at home this time.



#244762 Macro in the Red Sea?

Posted by zzz111 on 15 March 2010 - 09:35 PM in Dive Destinations and Travel

Going to dive the Red Sea early April, Deadalus and St Johns. Don't seems to see alot of macro pictures from the Red Sea, so what will I miss if I don't bring my macro gears at all?

I'm asking because my smile doesn't work at the check-in counters as magical as some other guys post here, tired of travelling with 40kg luggages, and trying to save couple kg by leaving out the macro port, extension etc., if these's nothing much to lose, or is there?

#239858 Diving in or near Italy, in April ???

Posted by zzz111 on 31 January 2010 - 07:27 PM in Dive Destinations and Travel

You should try the malta/gozo/comino dive locations


Thanks lomaro! More tips on the arrangement?



#239857 Diving in or near Italy, in April ???

Posted by zzz111 on 31 January 2010 - 07:16 PM in Dive Destinations and Travel

where in Italy?


I'll have 2 weeks, Apr 11-24, haven't figured out the details, first time there. The trip should be mostly topside, with 3 days or so in water. Topside recommendations are also very appreciated.



#239514 Diving in or near Italy, in April ???

Posted by zzz111 on 28 January 2010 - 07:56 PM in Dive Destinations and Travel

Hello guys,

Planning a trip to Italy in mid April, any good place around to get dipped in? Even better if someone wants to dive together. How about Malta?

Thanks/ben



#238187 help with dive trip planning - where and when to go?

Posted by zzz111 on 16 January 2010 - 08:19 AM in Dive Destinations and Travel

Thanks Francesco. That really helps, let me do more research from there.

I've been to the first 3 places, even the same resort in Manado, I liked it. And yes, I live in Shanghai, actually I'm a native here. Let me know if you'll stop by.



#238165 help with dive trip planning - where and when to go?

Posted by zzz111 on 16 January 2010 - 05:13 AM in Dive Destinations and Travel

Hi Ben!

Since you're on Wetpixel, I'm presuming that you either shoot stills or video underwater. I've found it's best to book trips that are geared toward underwater imaging... locations to capture great images, resort/liveaboard staff to accommodate the needs of shooters etc. While there are a number of dive trip organizers out there, I'd personally recommend checking out Under Exposures:http://www.underexposures.com/
They have several trips a year that go to great locations, and all are led by photo pro, Berkley White. The person to contact at Under Exposures is Dan Baldocchi, and his info can be found on their web site. If you are interested in one of their trips, Dan will take care of all the bookings for you. I've been on several trips with them and Dan is very thorough and reliable. Wetpixel also has some great trips every year. You should check them out too.

Regards,
Jen


Thanks Jen! I'll contact Dan and see if I can join some of their trips.

BTW, yes I shoot stills, and since I use canon 5D2, I shoot video sometimes too - but playback is enough a headache for me, let along editing, I'm waiting for their new firmware to support 720p, that should suit me better. So I'm looking for photographer friendly resorts/boats, with equipment rental - I don't bring dive gears since camera is enough weight for me to travel with.



#238164 help with dive trip planning - where and when to go?

Posted by zzz111 on 16 January 2010 - 05:10 AM in Dive Destinations and Travel

Ben,

it would be helpful if you list places where you have already been and kind of photography you like (macro, wide-angle, big animals, natural light wide angle ....)
I do have many suggestion for you, but the list would be enourmous without knowing your preferences !!!

All the Best ..... Francesco


Thanks Francesco!

For the past 5 years or so, I usually dove 2 or 3 weeks a year, my divings are mostly within Southeast Asia, Huawaii once and no where else. I like both macro and wide angle, seems I like all things wet, it's probably easier to list what I don't like about diving: I'm skinny with heavy camera, so I don't usually like beach entry, I'm not good with colder water (wet suit 25C or below) but if it's worth it I can talk myself into that deep cold water, I don't enjoy long lines at check-in counter and security but divers have to live with them. Another problem is, my camera is already overweight so I don't travel with any dive gears, need rental on site, so boats without equipment rental are out.

This year I'm open to mostly anywhere - better be within 2 or 3 flight hops from Shanghai though. I'm considering Malta and Red Sea right now, not sure if the Americas worth the long flight compared to Southeast Asia. But I'll travel to the US anyway, so probably I'll dive for at least one week in the Americas too. Besides, I've never tried dry suit, not sure if I should explore some cold water destinations, how long does it take to learn dry suit?

My failure booking the trip for next month educated me that planning is necessary. But now I see planning is a real headache, I'm totally lost. With help from you fellow divers I hope I can form a plan in couple weeks, taking into consideration time of year, route optimization and I don't know what else :-)

Thanks again and help please!



#238050 help with dive trip planning - where and when to go?

Posted by zzz111 on 15 January 2010 - 08:22 AM in Dive Destinations and Travel

Dear fellow divers,

Just realized I needed a plan for the year when I failed to book tickets for a dive trip next month because of local festival.

I'll have 8 to 12 weeks to spend underwater in the next 12 months. It would be very appreciated if you could share your thoughts on overall planning, such as where and when to go for the best diving destination, so that I can plan well ahead, enjoy some early birds cost savings and most importantly avoid the problem I just had. I'd usually stay with a resort/boat for a week, so I can visit 8 to 12 dive destinations this year if well-planned. So, kindly your recommendations please!

Reputable vendors are also more than welcome to contact me if you're interested in offering an overall package recommendation.

Thanks a lot!

Ben



#230948 Focus lights versus 'dedicated' video lights

Posted by zzz111 on 10 November 2009 - 10:29 PM in Lights, Strobes, and Lighting Technique

Fisheye is releasing a diffuser and color filter set for the LED500 that will allow you to lower its color temperature to match the Hartenberger light. These will be shown this week at the DEMA show, and shipping within the next month.



Ryan, does this work with the LED1000 too? I'd like both colar temp correction and red filters, can I have them both ready when diving? from the picture seems i'll need to remove one of the color filters to fit the red filter?



#230932 Macro with Canon in Ikelite

Posted by zzz111 on 10 November 2009 - 07:08 PM in Digital SLRs/Housings

Thanks Bent, your answers are very helpful.

I just got a reply from Ikelite saying "there's no modular option with manual focus", that might explain why you had difficulty make the focus extension work. But I'm confused if that focus gear is not designed for 100mm macro, then what's it for? I hope you can make it work with some soft foam padding or so, and pls share the result. I admit my most frequent use of the manual focus gear is to dial streight to minimum focus distance and then move the camera, without the focus gear this is still doable in AF mode with AF function moved away from shutter, but turning a nob is much easier.

Has anyone every dreamed of having camera vendors enable us manual focus using the lens motor, say use the AE lock and zoom in buttons to drive the lens motor in and out? This will save us all the troubles with the focus gears, the motor needs to run in very low speed though. I'd be happy enough if they just have a "reset to minimum focus" function, and for this they don't need a multi-speed motor.

Bent, pls let us know how you like the mods after you get the housing back. I'm never too worried about the locks, but I'm very interested in the top mount, is it strong enough on land, hate to use 3-way ball clamp for focus light.



#230874 Macro with Canon in Ikelite

Posted by zzz111 on 10 November 2009 - 08:51 AM in Digital SLRs/Housings

I have used both the Kenko and the 500 with the old EF 100 and Ike´s modular portsystem. It works pretty well, however I find it to be very specific in use. I will probably add a wet diopter rather than the 500D in the future in order to have more flexibility during dives.

If you have specific questions on the set up, please let me know.

Regards

Bent


Bent, I'm very interested in the specific tubes you use to house the lens only, kenko 1.4 with lens, and the 3 together. Did you use the manual focus extension tube? Hope it works with the 100 macro lenses, could have a hard time without manual focus in supermacro.

I also plan to use wet diopter when I'm not sure the whole dive will be supermacro. With wet diopter, I heard it's very important to have the lens glass very close to the wet diopter, how close is your lens to the port in these modular setups? And how close is enough for wet diopter?

Thanks a lot!



#230848 Floatation collar and ring flash 2 in 1?

Posted by zzz111 on 10 November 2009 - 04:05 AM in Digital SLRs/Housings

Just come up with the idea, since the 2 looks alike (more or less), and both are good to have for macro, why don't we have them both together?

I'm not good at DIY, but I really hope someone try it out if you like the idea, and I wish I can buy one someday from a housing vendor if it proves to work.

So it will be a sealed collar or ring flash attached to a macro port, with air trapped in, a clear window or 2 on the side(s), so you can point your strobe(s) to the clear window(s). Personally I would point one strobe to it and leave the other strobe where I want it. The air trapped in should help offset the heavy lens/port. there should be an opening somewhere, maybe the face plate of the ring be removeable with o-ring seal, so that you don't seal it permenantly say when you're flying, and you can try install different difusers or gels. The seal is not that critical anyway, the worst case you lose some floatation lift, for the dive.

What do you guys think?



#230845 Macro with Canon in Ikelite

Posted by zzz111 on 10 November 2009 - 01:43 AM in Digital SLRs/Housings

Steve,

Thanks for sharing your first hand experiece with the 100L lens on land. The 3 position focus range switch sounds cool, I too hope to hear from wetipixelers how its IS performs underwater especially with supermacro. I don't know how much improvement to expect from optics and focusing, haven't heard much on these. So the IS would really be the major point for "upgrade", if it really works well.

The size difference is quite annoying though, otherwise I can just keep my old port.

Besides, I want to try kenko 1.4x and maybe canon 500D with the old or new 100mm macro, someone here with experience on ike modular ports to hold them?



#230369 Macro with Canon in Ikelite

Posted by zzz111 on 05 November 2009 - 07:27 PM in Digital SLRs/Housings

Hello everyone,

I have some questions on macro/supermacro with Canon 5D2 in Ikelite housing, really appreciate if you could help shed some light here:

- the new 100mm L lens, worth upgrading from 100macro usm? how do you rate the improvement in scales 1-5, in aspects like optical, AF speed, IS feature good or bad (given that we can't turn it on/off underwater)

- it's a little longer than the old 100macro so I figure it won't fit in the ikelite focus macro port, has someone tried the ike modular ports with this new 100mm L lens? does the ike modular focus ring work with it?

- beyond 1:1, canon 1.4x/2.0x or kenko, anyone likes to share teleconverter experience with canon 100mm? and the ike modular port configuration?

- beyond 1:1, diopter: the ike 100macro focus port is so tight there's simply no room for any dry diopter, with modular port system dry diopter should be possible, could you pls share your favorate diopter with canon 100mm?

- what are some 3rd party wet diopter options available to ike ports? experience?

Thanks alot in advance!
