FOR SALE: Preowned, used Seacam Superdome 9" (~240mm) glass dome port. Overall in pretty good condition. Plastic (removable) shades are plenty scratched, as usual, but obviously they no effect on performance. Majority of the center glass in very good condition. NOTE: There are a few scratches on the dome's outer surface, positioned out to the sides. Detailed info on the scratches: On one side, there's a ding about 2mm, roundish. Red dot on photo gives approx position. Note that this is well out of the center area, off to the periphery. Then on the other side of the dome, pretty much opposite, there are a few scratches. Red circle on the first photo (wide photo showing the entire dome port) show you the general area where they are positioned.. Once again, note that they are far from the center. These are not deep- I don't feel them with my fingernail. These are kind of like "scuff scratches", and definitely not as bad as real scratches or gouges in terms of affecting image quality. (I have been shooting glass domes for 35 years, and I keep shooting domes until they are in far worse condition than this... I'm only selling this now because I sold my Seacam housings a while back and this has been sitting unusued in my closet.) Size-wise, there are a couple scratches about 1 cm length. And then a couple more about 1 inch in length. All kind of in the same general vicinity. I had a hard time photographing them so that they would be visible in these pictures. The 3 close up pictures attempt to show the scratches. It's possible that when shooting into the sun you, sometimes, may see some indication of these in the photo, but not in the main center area of the frame, not over where most/all of your main subject is likely to be, because all of these are far away from the center. When shooting coral reef scenes, wrecks, etc. at depth, or blue water with the sun at your back, or on overcast days etc., I honestly don't think they will be noticeable in any way. When I was shooting Seacam I was still using this dome regularly for all kinds of images, splits and underneath, with a variety of lenses (fisheye, 14mm, 16-35, etc.) and I did not feel the need to replace the glass yet. Asking $575 USD, with payment via Paypal (or cash in person). Price Includes shipping in the contiguous USA. Seacam shooters already know how expensive these are new, well north of $2000 USD. I'm doing my best to offer this at a price that accurately reflects the dome's condition and still represents a good deal for someone out there in need of a big dome who wants to save money. Thank you, Brandon

FOR SALE: Inon Z330 strobe. Preowned, well used. Not the prettiest specimen cosmetically, but still does its job. I just shot it in April in BC. NOTE: Focus light does not work, and hasn’t for a couple years. But being weak and off-center, it was never that useful to begin with, to be honest. So I didn’t miss it. Main flash tube is still excellent. Battery compartment clean. Never flooded. Electrical sync cable bulkhead clean. Never flooded. Front dome element excellent, as it almost always had a diffuser covering it. Note, 2 diffusers are included. And Nauticam angle ball mount also included, as well as spare new o-rings. I will also throw in a set of 4 Eneloop Pro batteries if you want. Well-used batteries, but would be a handy backup set to newer ones. Asking $250 for everything shown here, payment via Paypal, shipping included in the contiguous USA. Thank you, Brandon

It is very similar to the LX100/LX100II. I had 10 yrs ago the LX100 and it was a very good compact camera for underwater use especially for video. I just hope the LX10 does not have the LX100 plague i.e. a non dustproof lens barrel as it was an expensive repair to have the sensor cleaned.

Yes, please ask... I think there are several interested...

I, personally, am not a compact camera UW photographer... This camera looks to be an alternative to the common Sony and Canon compact cameras used UW? https://www.dpreview.com/articles/9011490317/panasonic-l10-2026-tour-controls-changes DivePhotoGuideNauticam Announces Housing for the Panasonic Lumix L10

He closed his shop several years ago, but since I know him very well personally, I can still get materials from him. I can ask if he might also sell to third parties.

Can you please give details about the manufacturer and how to order the floats?

Which dome are you using with the 24-105? Is the IQ overall better than EF 8-15/4 (center and edges)? I could not detect any difference in autofocus behavior between the Canon EF/RF adapter and the Commlite. Did you also test a 1.4 extender? So far, I've only been able to compare the extenders over water: In the center of the image, there's virtually no difference in image quality between the Canon RF 1.4 and 2.0 (zoomed to 200%), but at the edges, the 2.0 is noticeably worse. And my old Kenko 1,4 Teleplus Pro 300 DGX performed significantly worse than my Canon RF extenders in all situations, especially visible at the edges. What I noticed: with the combination of Commlite + Canon RF Ext., you should switch off the IBIS in the camera, otherwise there are strange, disturbing shake corrections in the viewfinder.

Here is how I would rank it, IQ sharpness wise: 1.) RF 24-105 STM (the sharpest!) 2.) Canon EF 8-15mm with original EF-RF Adapter 3.) Canon EF 8-15mm with comlite EF-RF Adapter (I have not shot this combination, as the comlite seems to exhibit some dismal AF performance compared to the Camon EF-RF adapter already on land) - so this is a „I suppose“ line 4.) Canon Fisheye 8-15 with original Canon RF-EF adapter and Kenko 2.0x TC 5.) Canon Fisheye 8-15 with modified Comlite RF-EF adapter and Canon RF 2.0x TC

I think the answer is with a 1.4/2x you are always further away than you would be with a bare lens and with a wet lens. With a 2x you can match nearly a 100mm macro with an SMC-3 (2x vs about 2.2-2.3x depending on which macro lens). Basically more water between you and your subject which will degrade the image. If you back off to get 1:1 with a 100mm_macro/2.0x you have the reach of a 200mm macro, so if you had a 100mm lens with 300mm focus distance and 150mm working distance at 1:1 you would double that distance with a 200mm focal length lens depending on how much the lens reduces in focal length to achieve 1:1 with and IF design. It gets worse as you progressively shoot larger subjects. A 1.4x might be a good compromise to give a bit more working distance compared to the bare lens and wet lens at a given magnification.. Also bear in mind that the longer focal length of the lens + TC combo will give you significantly more magnification than the bare lens with the same wet lens. For example the m43 Pany 45mm lens gets 1.6x with CMC-1 while the 60mm macro gets 2.0x (both 1:1 lenses) and 60mm is near 1.4x 45mm. so the new Sony macro might go from 2.4x with SMC-3 to 3.3x with a 1.4x and 4.8x when used with a 2x. So a 1.4x/2.0x locks you into smaller subjects than a bare lens/wet lens combo does and the impact would be noticeable I think in the 0.5x -1:1 range and lower magnifications unless the water was crystal clear. It may work well for skittish mobile subjects like small fish if this was the sole subject of your dive. You might also degrade AF performance with the 2x at max magnification again depending on lens/body combination

Interesting! How am I supposed to understand this sentence? Does the fisheye lens without any extender (adapted to the camera only with the Commlite) have less IQ than the fisheye lens with the Kenko 2.0x PRO TC? But you also have to adapt that one to a Canon DSLM with some adapter...

Yes, I've had the strobes for a few weeks now, but I've only been able to do one test a few days ago in the pool. In a week, I'll be diving in the North Sea for a few days and will then have more information. However, the dives will certainly take place in very poor visibility and I obviously won't be able to test the actual flash power then (as I would in backlighting and clear water in a coral reef).

Thanks. Bit more shocked than I thought we would be - but ok. Having survived (!), the gear loss is utterly depressing. I'm going to need some expert advice from you guys on what direction to go next. Slowly, slowly.....

I am happy Canon made this lens. 20mm is the sweet spot before rectilinear lenses start looking odd. I hope the lens design pops up on optical bench soon, so we can have a closer look.

Hi everyone, I'm an owner of the R5C which I really like. I'm looking to change for 2nd camera (BMPCC6k) for this last canon cinema camera. Does anyone did use it underwater and as any review about it ? Thank you

Having done a few more snaps in the field and tightly comparing the sharpness of my lens line-up, I must conclude: Newer RF lenses are more razor (sharp) than older EF lenses. This basically confirms also various land based tests I churned through on the internet. Surprisingly my RF 24-105 STM is the sharpest lens in my lineup and it outperforms the EF 8-15 fisheye in overall IQ sharpness on average. I even think the RF 24-105 is sharper than the Canon RF 100 mm macro behind a flat port on many occasions. Also I am currently under the impression that the EF 8-15 combined with the Kenko 2.0x PRO TC performs better than with the RF 2.0x comlite adapter.

@TimG my condolences! What a nightmare. I hope you are not too traumatized by the experience and the gear loss aftermath.

So you made the jump to new strobes @waso … were you already able to take them out for a test drive ? … interested to see your first results with them soon.

Similar complaints from my better half here, too. She usually says something like: „Oh nooo, are you going to watch Shrek again,… ?“ before she leaves the room. 😅 🥴

After using several GoPros for many years, I decided to switch to the Osmo Action 5 last year following extensive research, and I’ve never regretted it. Due to its smaller sensor, the GoPro has a significant drawback, especially in low-light conditions like those found underwater. Footage shot at greater depths and in caves/caverns/overhangs is heavily noisy, whereas the Osmo Action offers clear advantages in these situations.

Update: 1 sold 1 ball mount left $25

There was another semi-interesting release from Laowa same time, the 35mm macro AF lens. But maybe its bit too wide to replace 100mm+MFO-3? But looking forward to seeing more of these manufacturers rolling out AF lenses. Definately waiting on someone to test the fisheye uw.

Basically title says it all. Action cam will be stuck on top of A1ii, main purpose is to film "everything" in the blue like hammers ect 20-ish meters away, scenery in Indonesia, ect. Main is cost effectiveness, so camera and "original" housing from the camera maker. Is wideangle wetlens needed? Or does the additional price justify it for my described use? The price range and what ChatGPT is suggesting, are all the obvious suspects, GoPro 13 black, Insta360 Ace Pro 2 and DJI Osmo Action 5 Pro. And Inon UFL-G140 ZD. The prices of this setup is pretty much what im willing to do splash out. Only thing is which one.

Good plan on the backups, Robert. One other fly in the disaster ointment I’ve found. I have a UK SIM in my phone. My provider will only mail out a physical SIM to my UK contact address. Won’t email out an eSIM nor mail overseas. A local SIM has restored some functions but many remain inaccessible till I get that UK one. I’ve been on liveaboards where the CD has collected all passports and kept them in a dry bag with a Satphone at the entrance to the salon. Very wise move. We all had go-bags but they were in our cabins. One or two were able to grab these but the majority couldn’t.

Thanks. I suspect banjar would know very well about this already...as in no way villagers can keep a haul this big a secret nor Banjar would not ask for a cut ;/ Sadly radio silence so far in there. But will see if I can somehow get through to them indeed, who knows. Yeah, Segara, locals fishing on the shore and throwing lines good 50m+ onto the dive site.
