a help with extension tubes

im on tight budget at the moment and next week im going to aberdeen, scotland next week - will be a good experience for me to

photograph at there.

 

At the moment i couldn't afford the macro lens like sigma 105mm macro lens, so the kenko extension tubes set kit would be a optional for

me. (i've got a canon 350d)

 

1. I heard that the kenko extension tubes set kit will not with EFS lens, is that true?

 

2. Does Jessop extension tubes kit set works with EFS lens?

 

3, IF Jessop's work with EFS lens, will it work well with my canon lens 18-55mm and 75-300mm non macro?

 

Thanks!

I believe that some old extension tubes will not fit the flange of an EF-S lens. I've just checked my set of non-Canon ones and they do fit.

 

Extension tubes that are currently being sold by Jessops for Canon lenses should be OK.

 

They should work with your lenses. You'll get the highest magnification with the 18-55mm.

 

I suggest you use manual focusing. I find moving the camera back and forth to focus is the easiest. A tripod helps as well.

Hello Dean:

 

I use the Kenko Tubes with my EF85 f/1.8 on the 40D. They work well (AF etc is fine).

 

I just tried to fit the tubes to my EF-S 10-22 and the Kenko Tubes DO NO fit on that EF-S lens.

 

I bought my Kenko Autoextension Tube Set (12mm, 20mm, 36mm) from B&H in Dec 2005.

 

Cheers! Jay

Neither the Canon or the Kenko tubes that Jessops sell will fit EFS lenses. What you need is the Canon II tubes or

an older set of non Canon tubes as mentioned by Henry.

You need the current, Kenko "DG" tube set. These *will* work with EF-S lenses.

 

Don't buy the *older* Kenko set that doesn't have the "DG" designation on it. Won't fit EF-S. (FYI: I understand it's a relatively minor modification to make them work... having a set of these tubes but not having any EF-S lenses, I haven't looked into it or tried it personally.)

 

Does Jessops have their own extension tubes? If so, I don't know if they will work with EF-S or not.

>> You need the current, Kenko "DG" tube set. These *will* work with EF-S lenses.

 

No they don't. I just tried it.

 

According to all publications, the only tubes which will fit EF-S lenses are the Canon's Mk II tubes.

 

Happy shooting,

Reports I have seen suggest that Jessops own brand tubes DO fit EF-S lenses. However, just in case they are digging up some old stock which might not be compatible to palm off on you, I would mention that you wish to use the tubes with an EF-S lens and it is important that they will work with it. By making this clear to them, you are making it a condition of contract. You may also wish to consider the Canon and Kenko EF-S compatible alternatives mentioned by others above and decide among them all based on your evaluation of build quality against cost.

Look at the tube from the lens side. EFS lens need a larger diameter openning for rear EF-S guard to fit. For the

Canon version II (EF-S) tube, the inner opening is only about 1 mm from the lens contact pins. If you look at B&H,

their Kenko tube picture shown the older one which (I have) and won't fit EF-s lens. Note: B&H like only has out-

dated pictures. If you look at ebay, there are

some newer Kenko version which look like it could fit EF-S lens. Since there are many old stock, the only way you

can be sure is try it

before you buy it.

I guess another alternative would be to buy the Kenko tubes and an EF50 f/1.8. Cost would be less than $250.00.

Another option: Pro Optics extension tubes from Adorama. They might not be the brand names of Kenko & Canon,

but they're decent, especially since there is no glass involved. They come in a set of 3 (31mm,21mm & 13mm) for

$84.95USD. They do work with EF-S lenses. I have a set and have had no major issues, except in in some

circumstances having to manually focus. But, other than that they are fine.

I hope this helps.

i heard that if i get kenko set kit i could 'mod' it to make it work with EF-S, is that true?

 

if so, how? :)

There is no reason why any set of tubes that allow you to mount an EF-S lens and have the right electronic contacts shouldn't work with your lenses. AF may be trickier, but that is all.

<p> Well, you learn something new every day. I should have wrote: According to all publications <i>that I read to date</i>, the only tubes which will fit EF-S lenses are the Canon's Mk II tubes. </p>

I have a set of Jessops extension tubes and they work just fine on my EF-S cameras (20D & 40D).

"i heard that if i get kenko set kit i could 'mod' it to make it work with EF-S, is that true?"

 

You'll have to do a search... It involves a Dremel tool and a small grinding wheel. That's about the extent of my knowledge of it so far... (because I don't have any EF-S lenses).
