Playing with my Canon 100mm Macro Lens with a 2x teleconverter

Here's some of mine taken with large f numbers and long exposures using a 150mm macro.

Hi sphelps

Very nice pics and great suggestions! I was shooting by merely pressing
the lens against the glass, without the tripod. I was hoping not have to but
you're right. I'll have to bring out the tripod and also be a bit
more patient to get a greater DOF. I'll try it out in the next couple days.

BTY, what's your take with teleconverters and using extension tubes along with it?

Here are a few more new pics taken today as suggested by sphelps. I used a tripod, remote and lowered the aperchure to f20. Pics turned out much sharper but I was not able to get closer to the subject as I liked to. Perhaps, I will try using extension tubes the next time (will have to buy it first).

Hope you will enjoy these too!

Those are much better, stunning really. Some still a little soft, make sure you're always shooting perpendicular to the glass. I don't have much experience with teleconverters for macro shots, not something I would probably use as the extra glass will probably work against you. I like the extension tubes better but they only allow you to focus on objects at a closer distance so may not always be useful with aquarium pics as tank glass typically gets in the way. As for using both not sure what the goal or results would be like but you could always try. Also consider a lens reversing ring for ultra macros.

This is like the dark side of the moon...time to take some hallucinogens.

Seriously beautiful though.....
