What extension tubes do.

[Poseidon]

Yup, you can use them with your D300, or a D3, or any other SLR camera that you can change lenses on.

Cool!!! how much do they go for?

 

[Poseidon]

Way to much for what they are, but I think they are about $140 for a set of 3rd party ones, and the OEM ones seem to be close to $100 each.

*edit*

I just went and checked, the Kenko tube set is up to $169!!!

 

[oceanparadise1]

WOW, i gotta check to see if i can get them but u said they are not made by nikon right? so i probably cant

 

[Poseidon]

Nikon certainly does make them, but they are way more expensive then a 3rd party manufacturer, like Kenko.

 

[oceanparadise1]

Well im going to check if i can get them throu cc and see if i get the same discount which would make them like 20-40 bucks a piece well depending on the original cost

Hey Poseidon, is a teleconverter the same as what you were calling a diopter?

 

[Poseidon]

Nope, a teleconverter goes between the camera and lens, a diopter goes on the front of the lens.

For Canon, look for a 250D or 500D, I think Nikon calls them 5T, 6T, etc... Not sure on that one though.

 

[oceanparadise1]

are they expenisive

 

[Poseidon]

Which? Teleconverters from Canon cost about $279 and Diopters are about $100-125.

 

[oceanparadise1]

wow i cant wait for my new camera and then i can bc i know im gonna spend alot on these types of things lol

 

[Poseidon]

You have to be careful, PHOTOGRAPHY can be just as addicting, an maybe even as expensive as REEFING!

 

[Lytehouse]

[oceanparadise1]

I have a Nikon D40 with the kit lense. I bought a set of Kenko extension tubes: 12mm, 20mm, & 36mm. If the coral is 4 inches back from the glass the only one that will focus is the 12mm. Is that due to the quality of the kit lense? I want to order the 105mm macro lense. Would that do the same thing?

I'm kinda disappointed with them. In order to get a really good closeup I'd have to move the corals right up to the glass (which is not possible with some of them). I could probably get the same thing I'm getting now with crop and zoom in PP.

 

[Poseidon]

H@rry, it is not the tubes that you are disappointed with.

And, for web purposes, you are probably right, you may get the same results with a crop in post processing, but for actual prints, you would notice a HUGE difference.

That macro lens would be an excellent choice, and the tubes will become of much more use.

Oh, just for reference, the coral I used in this example is about 9-10" away form the front glass.

 

[H@rry]

Kewl, 9 - 10 inches will work. I can reach most of my corals from that distance. Do you think I will get that much reach with the macro lense?

 

[JuniorMC8704]

LOL, ill show you something funny if i find the time tonight.

Ever seen what the cells look like that make up a feeder tenticle?

Ill throw all three extension tube on my macro lens, and then twist on my Canon 250D close up filter...:hammer:

 

[Poseidon]

That would certainly ROCK Jr!!! I really need to get a true macro lens....

 

[Saltysteele]

aw, man... i'm really looking forward this......
