Let's talk tubes

I could only read what they had on the page. If you have a set, I am sure you are correct.

OK since I am new to tubes (and this was my impression of the price range :P ) would I be better served to get these www.amazon.com/Fotodiox-Extension-Extrem...id=1308326954&sr=8-2 ? I know I loose aperture control as well as auto focus or would my money be better spent on the set that maintains electronic lens control?

You'll probably learn more using the cheap all manual variety. It will take a few steps to make an image, so the tripod is going to be a necessity, not a luxury.

Your choice though. The electronics let you shoot much quicker, and possibly handhold a few.

HTH :)

That really is a personal choice...Shooting macro normally means manual focusing, so the absense of the electrical contacts really isn't a big deal in that sense. As for metering, no contacts means no metering (at least on my camera) but that doesn't mean it can't be used. I shoot with older manual focus lenses on a regular basis & non of them will meter with my Nikon D70s. If you look at my galleries, most of the photos were taken with the older lenses. I used "Sunny 16" to get in the ballpark & then the LCD & Histogram to fine tune my exposure. A little bit more work, but perfectly usable & no problems with macro shooting...

edit,
My shots are almost all handheld, no tripod, but I use flash for supplemental light allowing me to use faster shutter speeds & smaller apertures...

Gotcha. I am thinking trying the all manual ones, the focus doesn't bother me as I am also breaking in the new legs. The loss of metering does bother me though. I still rely on my light meter in camera to help me get in range before I start to tweak. Maybe use the light meter add the tubes and play around? Flash is also on my learning schedule so that doesn't bother me as well. Since my main macro is floral and not insects my subject is more patient shall I say :lol:

Thanks everyone for the help!

I had exactly the same requirement as you. I wanted to take some macro images, but didnt think I had a need for a full macro lens. I bought the Kenko tubes from Amazon. They come in a set of three so you can add the one that you need (or all three for really close work). I decided that they work best with my 70-200 lens, and with the macro tubes on, you can focus pretty easily with the zoom ring. The long lens means you are further from the object as well, so you don't block the light with your lens. I don't want to make a habit of this on this forum, but I did a Blog post about macro photography not too long ago!

Steve-
do you feel they were worth the cost? I was under the impression tubes were inexpensive and money is tight here. I have a macro lens but I want to boost it's abilities. I wonder if the Zeikos would work just as well?

I wouldn't worry about AF tubes, I recently bought a set of the latest Kenko AF Tubes and unless I'm using the smaller of the tubes AF on the 50mm is useless and have switched to using manual.

Generally speaking from my plays with them AF is not really an issue as your focusing so closely on the item that the smallest movements will bring the subject in and out of focus anyway. Fun when your trying to shoot close ups of flowers in a breeze lol...

A bit that I haven't investigated is whether you need the electronic connections in the tubes to make the aperture close down? I understand about the focus, and I agree that I almost always focus manually (using the zoom ring in my case), but I am focusing at full aperture and then it closes down to take the shot. Do the cheaper tubes do that?

Hi Mj,
Definitely stay with an auto-set of tubes, Steve gets 10 points :) ...

While the manual tubes will allow metering in some settings with a Canon, they will not stop down the aperture. This means you'll be forced to shoot wide-open when using an auto-lens, so can't control depth of field.

If using tubes with a macro lens, you'll probably get by fine with the less expensive auto-set. However, if you can go the extra, the Kenko have a better build, but it's your call. I've used both, and had little problem with less expensive plastic sets made by similar companies such as Opteka.

Here's a little more info that will help you determine the additional magnification you'll gain from tubes, I hope you find it helpful. The example shots are shown using a 50mm macro with tubes.

Lastly (if using a 100mm macro lens), (budget thinking...) it's also possible to use a tele-converter with your macro lens. Unlike tubes, they do have glass elements, so you lose some quality. However, converters such as a Kenko allow infinity focusing when attached (The Canon Converter will not work with any macro lens though). Another advantage is the Kenko work with your longer lenses for birding too. It's all a matter of which you think you'll use most, ie: Converter, or tubes?
