greeneggs! Love the name. Welcome to Waterpixels - great to have you with us.

Hey Marc! Welcome to Waterpixels - great to have you with us. We hope you really enjoy the site. Have to say, I love the look of your hotel pool especially looking out on a great, bleak Amsterdam morning!

Welcome! I’m sure you’ll see lots of familiar names. Good to have you with us!

Correct: no access to home catalog while traveling. The edits exported with the travel catalog exported into the home catalog Switching between catalogs is straightforward.

I’m amazed anyone would write that the UWT trigger is not as well made. I’ve had an UWT in my Subal housings for about 10 years. The boards have been solid, well made, neat in construction, fitted perfectly in the housings and have behaved flawlessly. I have had the occasional minor problem with fixing the LEDs to the bulkheads but that’s not a UWT issue.

Following on from @Tino Dietsche’s suggestion, I’ve just this week moved to switching my whole catalog and library to an SSD. It goes back to the late 70s and has over 60k images totalling 1.4TB. As Tino suggests, now easily transportable and able to be switched between computers running the catalog off an SSD - which is passworded!

Hey Robert I’ve had the same dilemma a couple of times. I had a catalogue on my travel machine with a different name to that on my home machine. When I wanted to integrate Travel on to Home I did a Catalog Export on to an external hard disk followed by an import of that catalogue into the Home catalogue. Seemed to work fine.

Me too!

Agreed on the 15mm FE. The Sigma was my go-to wide-angle lens for a full frame sensor camera. I never found anything else useful - but then haven’t used wet lenses.

John, last time I looked there didn’t appear to be two different neoprene cover sizes - unlike the bumpers. The new bumpers look like the same size in terms of depth. I reckon there’s a gap of about 2mm with the covers on the new strobes with new bumpers installed. Barely worth worrying about.

Hey biodives! Great to have you with us. Welcome to Waterpixels.

I’m with Barmaglot. If you were starting from scratch then, yeah, Z8. But I’d doubt the cost of the upgrade would be worthwhile

Hey Tino! Welcome! We're delighted you've taken the step to join us rather than just reading the posts. 😄 We hope you'll make lots of contributions. Great to have you with us.

Totally agree with Chris on his point over most users and the 20-30 MP. We’re being sucked into manufacturers’ marketing hype and 35mm film hangover, for the vast majority of us, on using an FF underwater. Big, painful for traveling, expensive and not generally necessary. I really liked my D800 (FF) based system but for traveling an utter pain. Now on a DX-based system (D500), I’ve got smaller, so generally cheaper, lenses and ports, less weight and bulk - and I cannot see a difference in image quality on a 27” screen or in prints as far as A3.

Chris’ makes a point I think important. If you have specific images in mind you need to decide what you need to use to create that. From my experience this works much better than having a setup that can shoot whatever turns up. It’s not only about gear in that case but also mind set. You “see” the u/w world differently if you know a site has creature x or wreck y and that’s what you want to shoot. But that can be difficult when you start out as typically you don’t really know what you want to do and just want to shoot everything you see! it becomes more of a consideration though when you’ve been shooting for a while and the initial excitement of photographing underwater turns into a more reflective phase.

No problems with the questions, Oretsis. That's the whole point of this forum 😆 I'm afraid an explanation of the optics involved is way beyond me. I just know what I use and the effect it will have. If you want to shoot largish critters who won't come close, then the 15-35 is the way to go. But because of the natural turbidity caused by water, getting as close as possible - and reducing the amount of water between the camera and the subject - is key. A fisheye of 15mm will let you do this better than a 15mm rectilinear - as you read from the minimum focussing distances you found. So you get close, but you still have the really wide view. The other point about using an FE is the size of dome you can use. Mine is a mere 100mm - tiny compared to a 230. This allows you to tuck strobes in tight to light a CFWA scene where, often, you are only cms from the subject. You just cannot do that with a 230 dome.

Hey Orestis Good that I'm not teaching you to suck eggs even though you love them! No, sadly the 15mm in the 8-15mm is not the same as the 15mm in the 15-35mm. The 15mm in the 8-15 will be, I imagine (as I said I'm not a Canon guy) a fisheye construction; whereas the 15mm in the 15-35 will be rectilinear - so not the curved effect of the fisheye but based on creating a straight, i.e. not curved, image. I don't know about the minimum focussing distances on those lenses but, generally, a fisheye can focus much close than a rectilinear. Usually for CFWA shots I'd use a fisheye plus a 1.4 teleconvertor (nothing is simple, right?) as this allows you to get VERY close to the subject but still have a wide field of view behind the subject - hence locating the subject against its habitat. If you already have the 230 dome then you are good to go with the 15-35 but will need some form of extension ring between the dome and the housing to provide the space the lens needs. Have a look on the Ikelite website for this. What you suggest as a start point sounds good to me.

Hi Orestis Forgive me if this is, using a British expression, teaching granny to suck eggs, but if you are new to u/w photog maybe the following might help with some context: One of the weird things about u/w photography is that you have to rethink how you view lenses. Wide-angle on a FF sensor can be tricky. Unless you plan to use the slightly more esoteric Nauticam lens additions (a more standard zoom plus one of the WWLs and the like), for wide-angle you tend to use the ultra-wide stuff. So a fisheye is often the norm for u/w. I can well appreciate you're not keen on the fisheye look but underwater you don't really see it as there are few-to-no straight lines to highlight the effect. You just get ultrawide. I'm attaching a couple of shots all of which were shot with a 15mm fisheye so you can see. The diver(s) was/were probably 2m away from me. The other part is that you don't really need the fast lenses either, eg, the f1.8s, f2s, etc. But you do need WIDE! So, in my view, I wouldn't bother to try and house your 24-105mm. 24mm is too narrow underwater and 105 not much use unless genuinely macro. The other "challenge" with wide-angle on a FF sensor is finding a dome that doesn't leave the corners of the image horribly soft. For example a 16-35mm lens on a FF sensor really needs a 230mm dome and, even then, edges can be a bit dodgy. By contrast, a fisheye lens has no problem. Strange world eh?!? I'm not a Canon user so can't comment on the 10-20mm zoom underwater but the range makes very good sense. Others will no doubt chip-in about how it works. Totally agree on the 8mm end of the 8-15mm. That is one specialist view! It's good for the occasional shot but not many. However the 15mm (it's a fisheye) is very good for u/w wide-angle shots. I'm sure others here will weigh in on the standard zoom plus the WWLs . They are a relatively new option and allow the use, as I say, of a more standard zoom lens but adding a chunky, pricey piece of glass in front. They do seem very versatile and would be worth you considering. You might need to do a calculation on the price compared to the classic big domeport route. There is also the issue then of moving heavy, chunky gear if you have to fly to dive. Macro: yep, the 100mm sounds good. I hope this helps!

Hi Sergio Sounds a good idea. We’ll work something up.

Good to hear, Christophe. I guess just the server catching up……

Hey Chris! Excellent to have you with us. We hope you enjoy Waterpixels. - and that sabbatical!

Hey Christophe Once you have posted your introduction - which you did above - you should be good to post. You need three posts in total to post on the Classifieds but other than that, you should be good to go. If there's problem, just let me know. Cheers!

Hey Chris! Welcome to Waterpixels - great to have you with us. Enjoy the forum!
