Both shots are with Canon SX30 at full optical zoom (150.5 mm) and 2.1x digital zoom. Shot 1 is with Raynox 150; shot 2 is with Raynox 250.
Approximate magnifications on sensor (i.e. not including 2.1x digital zoom) are:
Shot 1 with Raynox 150: 150.5 mm / 208.33 mm = 0.72x
Shot 2 with Raynox 250: 150.5 mm / 125 mm = 1.2x
Wonderful closeups!! How did you keep them from melting while taking your photos?
PS Just a side note--Letterman broke me up a few nights back when he said:
"Scientists have decided that all snowflakes are pretty much the same"
He has a dry sense of humor that really tickles me at times.
Thanks Biff & Murry.
How did you keep them from melting while taking your photos?
I have been taking lots of pictures of frost that forms on the inside of the windows of my garage, where it is usually a little below 0 C, while outside it has been -10 C and colder.
This time, the snowflake was outside, while I took the shots through the double-glazed window while standing inside. Snowflakes don't usually stick to the window, but this one was very tiny - only about 2 mm across. Yesterday was a bit warmer than usual, a bit below 0 C outside, with the garage a bit above 0 C, so I guess the snowflake was picking up heat from the glass, causing it to melt.
Very impressive, congratulations!
Nicely done Stephen, thanks for sharing.
To keep my brain active I'm looking forward to my next trip. So much to see yet and not enough time.
Great shots Stephen. - thanks for sharing!
I don't know anything about the Raynox - could you please tell me more?
I have the SX50HS - I suppose it will also fit?
How do you attach it to the SX and what else do you need apart from the Raynox itself?
Thanks again Stephen.
Thats incredible nice...

There are two Raynox closeup lenses:
The DCR-250 is the stronger of the two at 8 diopters with a working distance of
1000/8 = 125mm, or about 5 inches.
At full optical zoom on the SX50, the magnification is 215 mm / 125 mm = 1.72 x
(with infinite focus) and the depth-of-field is only about 0.2 mm at widest aperture. With narrower aperture or less zoom, you get more DOF.
The DCR-150 is 4. 8 diopters with a working distance of
1000/4.8 = 208 mm, or about 8 inches.
At full optical zoom on the SX50, the magnification is 215 mm / 208.3 mm = 1.03 x
(with infinite focus).
The Raynox closeup lenses attach with a spring-loaded "universal adaptor", which is what I use and find convenient, although some people prefer to use adapter rings.
If you want to choose just one of them, I would recommend the 150. Even though it is the weaker of the two, it is easier to use and more of the shots are keepers. The larger working distance makes it easier to avoid casting a shadow on your subject and you are less likely to scare insects away.
Focus-stacking is a fun technique for combining multiple shots in order to increase the DOF.
Here is one of my posts with some technical details about DOF, use of macro rails and the Zerene Stacker software:
Here are some of my stacked shots of small flowers taken with the Raynox-150:
If you don't want the bother of stacking, you can still get excellent handheld closeup shots. Again, I would recommend the Raynox 150. The price is around $75 U.S. if you shop around (includes the spring-loaded "universal adaptor"). You can have a lot of fun without any extra equipment. If you want to do focus-stacking, macro-rails start around $70 and Zerene Stacker is $89 U.S.
I hope this helps.
For your time, giving such a detailed answer - I appreciate - you surely know a tremendous amount of the technical side and - it shows in your images - kudos to you!
