In Topic: Olympus 60mm macro focus distance display.

Hi Bill,

 

I used exiftool to extract the information (free download) for my EM-5. I posted info on how well the distance allowed you to calculate the actual size of subjects in your image. You can find the post here http://wetpixel.com/...showtopic=52938

Thanks for the update. E. tutuilae is in my books but I would never have guessed it. The description states that is the most widely distributed and most common species of the genus and that its coloration is variable. The one thing Reef Fishes of the East Indies is less good in than the Reef Fish ID books is hightlighting exactly what aspects of the appearance are visually distinguishing marks. Fin ray counts may be of interest to their scientific audience but for us visual ID cues are critical.

 

By the way, the image for the male shows it with a bright red cheek, chest and leading part of the central dorsal fin. The description never mentions it so I expect it may be a mating or territorial coloration. It is supposed to also occur in the Red Sea so I can keep a look out for it on my next trip in May.

I would have thought that for manual focus finding 1:1 was actually the easy part. Just turn the focus all the way. Like Phil I don't think there is a way to display the focus distance while taking the shot. However, you can get the distance later as it is stored in the EXIF data.

In Topic: Compass handling - do you? How do you?

Hi Dave,

 

Like you I rarely need to use a compass but normally strap one on just in case. I just set the compass so it points out the direction to shore and so far have never needed to rely on it. I have done compass navigation on a few occasions but never with camera. If I had to I would not mix photography and compass reading but press the camera against my chest and focus on the compass until I reached my destination. In all cases I would have the compass on my wrist. I don't like retractors but if I would do a lot of compass diving then I would consider hooking up the compass to the housing. Perhaps someone can post pictures of ways to do just that.
