The Raynox M-250

This lens caused a little interest at the Toronto meet up, lots of questions such as "how much magnification.

Here are some image susing both the 50-200 and Tamron 70-300 with the Raynox latched onto the front.

The jumping spider is about 6mm wide, the yellow spider about half that and the salt is well ..... salt .

Great stuff.
Did you have to do any extra lighting with these shots? It looks like you used a flash on the last one?
What kind of aperture setting do you need?
How do you find the Pentax vs the Tamron?
Do you know what level of macro you're getting? (e.g. 1:1)
Sorry for all the questions, I'm waiting for the Raynox to be delivered, so I'm more than interested.

Thanks

Oh yeah, you ALWAYS need a flash. I just use the 360 but in need of a diffuser, badly in need actually.

What kind of aperture setting do you need?

f/22 to f/32

How do you find the Pentax vs the Tamron?

Tamron gets a little closer but 300mm is tough to hand hold.

Do you know what level of macro you're getting? (e.g. 1:1)

Some on DPR say i'm getting 3.5:1

No worries. Good luck focussing

Raynox DCR-250 (Adapter w/M-250) is a +8 diopter. It gives you different macro ratio on different lens. On a true macro lens, at 1:1 it gives about 2:1 macro. On a normal prime like FA 50mm f1.4 it gives about near 1:1 macro. On a Tamron/Sigma 70-300mm zoom, at 1:2/300mm it gives about 3:1 macro.

Yes you'll need use flash, unless there's very strong light source. Normally it gets sharp around f8-13. DA 50-200mm will give u lesser magnification but sharper image. Working distance is normally around 5cm when u are at max.

The truth is you'll get sharper image with reverse prime lens and ext tube.

Thanks Al and Zeek for the responses. I'll be trying the Raynox with all my lenses to see what works for me. I have and would intend to use a tripod for real macro stuff (like that salt, that's freaking incredible). I have a Sigma 530 Super flash with a built-in diffuser, and it angles down by 7 degrees, so that should help.

I considered extension tubes, but the concensus seemed to be that they lose too much light. Reverse prime lenses sounds like the cat's meow, but the Raynox is cheap and easy to pop on whatever lens I happen to be using, so I'll try that out for now.

I've been using a Raynox adaptor to get my 28-70mm zoom to act like a 28-70mm zoom (minus the 1.5 ratio). Now it looks like you've convinced me to try another Raynox to go the other way.
Great series. Thanks for sharing.
