No problem, they are nice to work with - right! One thing to remember, if you are posting these, browser are mostly default colour managed now, however they will assume your image is sRGB unless it is tagged otherwise, You do need to keep the colour profile in the file, there is generally a check box to include the colour profile in the file when you save. Unfortunately you need the good monitor to see the benefit, Apple users will be close, but if they are being viewed by photography enthusiasts they are more likely to have a good monitor. - Today

To all who recommended the Eizo…wow were you right! The photo and video quality is amazing, and this is on a 12 year old monitor! It really has me thinking whether I want a newer 27 Eizo to pair with the CX271, or if I’m better off getting a monitor better suited to HDR with higher resolution? Thanks again! -
North Sulawesi—NAD Lembeh on the Lembeh Strait. Going with Underwater Tribe, who was recommended to me as a great group of photo instructors. Plan to shoot mostly macro stills, but also try some video with the M10 and GoPro.

You can get very close with it, it compresses the range that will focus quite a bit, I haven't tested the limits of it at the short end, but the port chart says it will focus from 0-1500mm and get to 0.8x implying it will focus from the glass out to 1.5m away. If I need to get super close, it seems the best solution is often to remove the MFO3 and use the bare lens as you will get more magnification and working distance. The exception would be murky water with particles and you want to get closer to reduce backscatter.

Hi Chris Its very interesting that you mention this because I was wondering the other day how the focus range works with the MFO-3. So if infinity is 1.5 meters away - then how close can you get with focus set to minimum-focusing-range? I've only used my MFO-3 twice. The first time I had the limiter to 0-0.28cm. So needless to say I did not try it that dive. The second dive we aborted prematurely because of the conditions. So I have effectively not used it ever. haha. -
Look forward to seeing your photos and video from your new rig. What part of Indonesia are you diving ? -
It is possible that it is not getting brighter than 0 to reduce heat in the air. I'll try in a water environment. -
The video lights seem great. The more yellow photo is from Keldan Luna 4. I don’t see much change of brightness over +0 but I’ll play some more. If there are other good tests to do let me know.

Bag is 55 x 40 x 20 cm and with the insert is just about 1kg Seems to work fine so far Bill

I created the attached N85 focus gear for a Sigma 10-18mm zoom on my Sony a6700. I took the Canon 8-15 zoom gear that @Chris Ross posted here, and modified it to fit the Sigma. I'm using the housing zoom knob in the NA-A6700, since my N85-N120 adapter doesn't have the integrated zoom knob (my preference, tbh). While I haven't tested it wet yet everything fits and zooms correctly. A few notes/changes from Chris's model: Added the four "guide nubs" on the geared end to help keep the gear aligned around the lens Thickened the "front" end to make up for the smaller lens diameter from the 8-15mm Increased the length overall from 41mm to 54mm Used a few pieces of cloth medical tape to give the inside of the ring some grip in addition to closing up the clearance (honestly I didn't want to redo the model to make up for about 1mm total extra clearance) When aligning the gear on the lens, you need to make sure the guide nub doesn't catch on the white raised "lens alignment" dot. It will keep you from using the full zoom range if it is in the way An M3 locknut and 16mm m3 screw are used to tighten down the ring on the lens's zoom ring Printing notes: Printed in regular PLA, 35% infill, with a 7mm outside brim to promote adhesion to the print bed Used a Bambu A1 Mini, and have the 3mf if anyone prefers that N85 Sigma 10-18mm Zoom Ring v2-fixed.stl

If only I had a camera, will get one later today BVA

I had an SF-01 and sold it. Worked in manual mode ok and reliable, and battery life was good with the two 18650. Double sealed battery compartment. I didn’t like the light distribution even with cap, light color was ok. The steps in brightness were uneven, so if I needed only a little light I got often overexposure. I wouldn’t recommend it. Same as in lenses: cheap is weak. -
Photo! -
Regardless, I will take watt seconds over GN. At least I know how much energy is being dumped, the efficiency of the flash tube and reflector/lens design aside. The strobe test that is a sticky in this forum is one of the better if not best attempts at displaying relative power/brightness. -
I heard back from Harald at Seacam. These were his port extension recommendations for the SD and FMP-C and the Canon 8-15mm with and without the Sony 2X TC. CANON EF 8-15mm > Metabones V adapter > Sony 2X TC > Sony camera: SD SUPERDOME + PVL75 PORTEXTENSION (20 + 25 + 30) CANON EF 8-15mm > Metabones V adapter > Sony camera: SD SUPERDOME + PVL45 PORTEXTENSION (20 + 25) CANON EF 8-15mm > Metabones V adapter > Sony 2X TC > Sony camera: FMP-C + PVL55 PORTEXTENSION (25 + 30) CANON EF 8-15mm > Metabones V adapter > Sony camera: FMP-C + PVL25 PORTEXTENSION (25) I have the necessary port extensions on hand so I went ahead and purchased the 8-15mm, Metabones V and Sony 2X TC. I intend to try these configurations when I go to Bonaire. I won't have a zoom gear, so I'll be setting the FL between dives and I'll see how these configurations perform for me. -
I upgraded to a Hero 13 last year spring before our trip to Fiji. I wasn't happy with the quality without lights, although after many months I finally started playing with the clips in iMovie and adjusting white balance did some pretty amazing things. I bought a Backscatter Sharp Wide wet lens last fall and dove with it in December in Monterey. Very happy with the improved quality, but not with my ability to maneuver the GoPro in 5mm gloves. Picked up a tray with trigger, but haven't tried it out yet in water--seems to be a great improvement above water. The tray also gives me the ability to add 1 or 2 lights. I started getting interested in diving in Indonesia which means macro. GoPro doesn't do macro realistically so I dove down the underwater photography rabbit hole. I was somewhat restrained in camera and housing choosing the OM Systems E-M10 IV micro 4/3 camera and the AOI octo housing. I also got the 60 mm macro lens, port, and focus gear. I was less restrained on accessories, figuring I could reuse/resell strobes. I bought 2 Backscatter HF-1 strobes/video lights, various arms and floats, as well as an MF-1 with snoot and a Bluewater video light with the idea I can use the MF-1 or Bluewater light as a focus light. I've only gotten the camera and housing wet in the pool using the pancake kit lens and natural light. I'm pretty happy with the results. Heading to Cocoview in April for a couple weeks of intense practice along with a 1-day class with Mickey Charteris, and Indonesia or a couple weeks in July.

I've found that SnS DS-TTL works as INON S-TTL https://www.inon.jp/technicalguide/sttl-auto.html So it seems like a better choise for TTL and manual for cameras with built in flash. But mine Seafrogs optical trigger doesn't work with TTL signal, unfortunately. -
I have taken a different approach (Being a cheap bastard). I bought a Metz 44 l cabin backpack ($40) and then a set of padded dividers from Condition 1 ($60) so I get a very light weight, big carrying backpack for about $100. Bill

watt seconds has similar problems unless you are always using the same reflector design. The photons hitting the subject is always complex to measure. Bill

Just on our way back from Galapagos. CNH and Samba is highly recommended. We are already looking for a next one. I’ll post additional pics as soon as we are home.

Thank you so much for watching! Yeah the music tempo in the beginning definitely doesn't match the footage - especially when it goes underwater. I just loved the track for the drone clips and tried to force it. Upbeat drums and nudis don't really go hand in hand hahahaha. -
Oxnard, California – February 17, 2025 – Ultralight Camera Solutions (ULCS) has released three new accessories designed to solve recurring challenges in underwater photography: the Camera Dome Weight Trim Kit, the Stabilizing Plate for Video and Still Photography, and the AC-AQD04 Quick-Release Adapter. All three products were developed in direct response to requests from dealers and photographers who identified specific gaps in the underwater camera accessory market. "We had dealers asking for these solutions," says Ken Kollwitz, Owner of ULCS. "These products exist because people kept running into the same problems, and there weren't good options available, or the existing options had significant drawbacks." Camera Dome Weight Trim Kit: Adjustable Trim for Any Dome Port The Camera Dome Weight Trim Kit addresses a fundamental challenge in underwater photography: achieving proper balance when using dome ports of different sizes and materials. Acrylic dome ports create upward buoyancy, causing the front of the camera housing to rise underwater. Glass dome ports, particularly larger ones, add significant weight to the front of the housing. Both conditions affect a photographer's ability to maintain proper trim and control. The ULCS kit mounts to the bottom of a camera housing and allows photographers to add adjustable weight where needed. The design accommodates different dome sizes and materials without damaging the protective rubber pad on the camera housing base, a problem that occurs with similar products from other manufacturers. "Only one other brand offers a comparable solution, but it destroys the rubber pad on the bottom of their housings," Kollwitz explains. "We wanted to give photographers using different camera systems an option that works without causing damage." The adjustable design allows photographers to customize the weight configuration for their specific dome port setup. Price: $129.95 USD. Stabilizing Plate: Keeping Camera Systems Steady During Deployment The Stabilizing Plate for Video and Still Photography provides stability for camera systems during staging and deployment, particularly on boats in rough conditions. Heavily rigged underwater camera systems, with multiple strobes, arms, and accessories attached, tend to tilt and rock when placed on deck, increasing the risk of equipment damage and complicating pre-dive preparation. Kollwitz identified the need for this product after observing the challenge repeatedly in the field. While other manufacturers offer similar stabilizing solutions, the ULCS plate is designed to be more universal in application and priced lower than competing products. The plate works with both video and still photography configurations and accommodates a range of camera housing sizes. Price: $177.95. AC-AQD04 Quick-Release Adapter: Simplified Equipment Changes The AC-AQD04 is a 4-inch quick-disconnect arm designed for fast, one-handed attachment of underwater lights, strobes, snoots, and other equipment. The adapter features a push-button release mechanism and compact design that streamlines underwater photo and video setups. Built with fewer moving parts than competing quick-release systems, it can be operated with one hand and is fully serviceable for field maintenance and repair. "There are other brands making similar products, but ours has fewer moving parts, can be used with one hand, and photographers can service it themselves," says Kollwitz. "We also plan to use this as a starting point for other quick-disconnect products." While designed primarily for underwater photography, the AC-AQD04's simple, reliable mechanism makes it potentially suitable for applications beyond diving. ULCS has provided samples to professionals in the cinema industry for evaluation. Price: $44.95. Field-Tested by Underwater Photography Professionals Andrea Michelutti, underwater photographer and ULCS Brand Ambassador, has been testing the new accessories in real-world shooting conditions to validate their performance and functionality. All three products are now available through authorized ULCS dealers and at ulcs.com. -
GNs are really not all that useful except possible computing exposures in a studio. GN is a function of beam angle and distance. Watt second is a more useful measure when given. A strobe with a beam angle of 80 degrees and a GN of 32 might be similar watt seconds as a strobe with a GN of 22 and a 120 degree beam angle. And then there is the evenness, for lack of a better word, of the beam. Many strobe are really hot in the middle with a lot of fall off but they have a high GN because it was taken in the hot spot.

Yes, it fits after some modification with a round file. -
An interesting comparison. What do you mean by a modified RF/EF adapter? Does the teleconverter's extension part fit inside the adapter?
