I agree order yourself a pack of Pec_pads, They come in a big pack, just keep the open pack inside a clean zip lock to keep contaminants away. I think there's a lot of myth and legend around sensor ceaning, yes its delicate but the need for single use clean room grade swabs at multiple $$$ each is debatable. Probably the most important thing is a compatible fluid. Then be sure to wrap the PEc-pad on tight so it's not sticking out everywhere so you can swipe without brushing up against internals bits, this can transfer fibres and may also end up with traces of oils.

The setup is fairly similar and works just as well, the new housing buttons seem to feel more positive somehow when operating them and the finish on the housing is different, sort of satin finish seems somewhat water repellent. The AF is pretty good probably a bit of a step up in snappiness. I'm finding the tracking not quite as good as on the EM-1 II, I contacted OM system support and they tried to replicate and it seems like I might need to put mine in for a look as their camera didn't do the same, it seems to jump to a slightly closer object when tracking in macro. Really only noticeable when shooting at reasonable magnification.

Re-posting to see if changes impact image quality. Looks like an improvement but still not as vibrant as viewing on Photoshop.

Welcome Sandra, good to have you here.

Greetings John, good to have you here, your setup in Vanuatu sounds great.

The forum software seems to have sucked the life out of the image, the image as displayed in the gallery look better. https://waterpixels.net/gallery/image/126-miamira_flavicostata_3jpg/?context=new

Got my OM-1 housing wet for the first time today, had the camera for land based work for quite a while now. Dived the steps in Sydney, Air temperature 32°C and Water temperature a fresh 17°C. Quite reasonable vis bit a lot of whale snot algae. Here's a pic from today of the Miamira flavocostata nudi that has made re-appearance on the site.

No problem, a similar species is quite common around Sydney.

This is one of the fang blennies, possibly the sabretooth blenny, Plagiotremus azaleus.

Welcome Kate, good to see you here.

Hi Ross, good to see you here!

Hi Eric, good hearing from you. The aim is to get back to what Wetpixel offered and I'm pleased so many WP people have come across. Thanks of course for setting it up in the first place!

Looking at the images they look pretty nice as presented, however something odd is going on with the scaling. When I view the image on my monitor the last image is 256mm wide. If I click on it, it displays bigger and is 292mm wide. To compare I went into Photoshop as I know it displays pixel for pixel and a 1500 pixel image there is 350mm wide, while a 1200 pixel image is 292 mm wide. It would seem to me that the recommended pixel dimension is 1200 px to fit the column width at least as it scales on my display in Firefox. I can't notice too much difference between the image in line and the larger one when I click on it, but the image I suspect is not one that will suffer too much from compression, other images may fear differently. I'm viewing on a 27"display 2560 x 1440 pixels. As far as quality goes the biggest impact will come re-sizing the images - I don't notice much difference between a 50 and 70 quality image in most cases. Ideally it should display in line at native pixel dimensions for best quality - 1500 pixels is clearly too wide to the column here but it does display nicely if you click on the image.

Welcome! 12°C or so in the winter in Adelaide I believe, Sydney doesn't get quite that cold normally!

Welcome Oskar!

Looks great Dave, did you do any speed testing on them? I assume they must be close to specs as they are performing well.

I do see the service manual links don't work as the archive didn't download them. Perhaps you could link them or add them to this thread?

Many threads such as this can be found on the web archive, here is the thread as archived: https://web.archive.org/web/20230127185242/https://wetpixel.com/forums/index.php?/topic/54607-do-15mms-need-servicing/&tab=comments#comment-399921 We do need to be careful copying threads as I believe we need the permission of each contributor to copy it, but we are free to link to it and the archive is likely to be more permanent.

Good to have you here Ian.

Hi Peter, good to see you here. Looks like your cyclone may head a bit north of you.

There are various ways to correct colour in lightroom the most basic being colour temperature and tint adjustments. Colour temperature is blue-yellow and tint is magenta - green balance. So shifting to yellow removes blue and to magenta removes green. The torch needs to be surprisingly bright as it needs to overpower ambient light, the best way to increase its impact is to have it much closer to the subject. The ultimate solution though is adding a strobe, which is way more powerful than a torch.

welcome Wolfgang, good to see you here!

For me the question is " is there life without tea?"😂

Great project, thanks for posting the results.

An alternative I have seen used around Sydney dive sites is a regular pair of specs without side arms mounted on a go pro type mask clamp on your mask that you can flip up and down as required.
