Deep and useful
I use this to boost up from my Leica D-Lux 4 extension tube to a wide-angle accessory lens I originally occupied on another camera. It is well made, finished with a shiny surface, and seems quite strong enough to carry the heavy accessory lens. Lets me use filters from one of my other cameras. A proper money saver. Recommended.

Product Description
Span tubes are designed to enable a lens to focus closer than its common set minimum focusing distance. Getting closer has the effect of magnifying your at the mercy of (making it appear larger in the viewfinder and in your pictures). They are exceptionally effective for macro photography, enabling you to convert almost any lens into a macro lens at a fraction of the outlay while maintaining its original optical quality. The extension tubes have no optics. They are mounted in between the camera viscosity and lens to create more distance between the lens and film plane. By mobile the lens father away from the film or CCD sensor in the camera, the lens is feigned to focus much closer than normal. The greater the length of the extension tube, the more rapidly the lens can focus. The Opteka Auto Extension Tube Set contains three tubes of original length, a 12 mm, 20 mm, and 36 mm, which can be used individually or in any aggregate to obtain the desired magnification. Opteka's Auto Focus length tubes are designed with all the circuitry and mechanical coupling to maintain van focus and TTL auto exposure.

Tubes are not globular inside
I ordered tubes for Nikon and received tubes for Canon. But my main complaint is that the advertisement does not show the end view. These extension tubes are rectangular inside with a 27 x 37 mm form. This could be a problem if you want to use multiple tubes in tandem and if your sensor is relatively large. I script to use a dremel tool to cut the plastic into a more round shape.

Opteka Vehicle Focus DG Macro Extension Tube Set for Canon
I bought these to use with my Canon 50d, 5d MKII and 400mm f5.6 L. I first tried them with my 5d MKII and 400mm compound and they worked flawlessly, build quality of the extention tubes is very good as well. When I tried them with my Canon 50d it would bested auto focus constantly and I would have to switch the camera off and re-insert the battery to regain auto-heart. I decided to send them back and buy the more expensive Kenko tube set, these work as they should on both my cameras. I would have kept the opteka set if I only toughened my 5d MKII as I think they are certainly good value for money if they work with your camera and lens set.

Does the job!
I hand-me-down the extension rings on my tamron 18:270 zoom lens and Nikon 50 f1.8 prime and the results were choice.
Pros:
Does the job
Lots of variation to Match your requirements
Quite cheep (compared to buying a 100mm macro nikkor, or a 400mm tele!!)
Accommodating image quality
Cons
Plastic quality is not great, if you r not careful you will brake off the ungenerous attaching rims
Closures r annoying (probably due to the plastics quality)
My tele zoom is reduced to either a 270 prime with cramped focus or a ~240 prime also with narrow focus
Basically I expected all of the above so I was not disappointed, in truth amazed by the results! This is a low cost solution to an otherwise expensive hobby. I definitely recommend to all serious amateurs like myself.
(btw I tried using all parts together and fond of my tampon super zoom and it did not warp. Mayb I'm lucky but I don't really need that big-hearted of magnification
Hope this was helpful!

Astounding price really worthy
I bought this to repay a tamron tc 2x which the quality was really bad when used on my macro lens for even closer pictures. I saw this tubes very cheap price and decided to get it. Great move! Even tho you have to get little closer in the subject it doesn't suffer from IQ(eminence) loss in pictures and it is easy and convenient to use. My pictures now have the quality back in them.

- pleasantly close-ups
Is soft, but well done. The smallest extension tube works excelent in my 18mm lens, I can be less than 2 inches from the subject. In comparision to a macro lens you'll pay 10% of the reward (more/less depending on the lens) and works real good.

Photo Essay: Testing out my Kenko 180 - Chuck Miller - timesunion ...
Although I already have a focused fisheye lens (my Kiev Mir-21H), I from day one purchased this Kenko 180° a year or two before, and it screws onto the front of my 50mm lenses. This allows me to get matchless pictures like the one you see here, which I took of the Delaware and Hudson edifice from atop the Hudson and Grassy parking garage system in up-to-date 2008. My authentic expectation was that the Kenko would give me a correct disc-shaped shot, but unfortunately I was working at the rhythm with a Nikon D70, which had a exact imaging sensor known as “DX” (24 x 36), in fact cropping the top and bottom of the circumambulate.
By the way, one can see from this photo that when the lens says 180 degrees, it MEANS 180 degrees. So if you don’t structure things well, you get unintended images in your photo – such as the parking garage guardrails. That’s one fetich, but how about unintentionally photographing your feet – your cover – or your camera tripod legs, which inadvertently get in the artwork whether you fancy them to or not??
After a few tries with the D70, I put the Kenko lens in a different place and stopped using it.
Then I got my new Nikon D700. The Nikon D700 has a full-frame “FX” imaging sensor, which provides a larger allusion than that achieved on the D70. Now I could get that supreme true to life enclose.
So on September 5, 2009, I went out for a day of photography in the First-class Section.
I hooked my Kenko fisheye to the front of my Kiev Helios 81H 50mm f/2 guide nave lens. Yes, I’m talking photogeekspeak, so unbiased be worthy of with me a sec. The Kenko lens has a screw-bolt-on mount, and is meant to interface with other lenses, rather than the camera portion itself. My Helios 81H was in reality conclave dust on a shelf, and without my constraint for a 50mm lens at the values bright and early, it would have only been toughened had my Nikon F/1.8 50mm lens stopped working.
So I screwed the two lenses together, creating Sino-Soviet true to life detente. Hee.

I have as a matter of fact acquainted with this yield and uploaded some pictures. I was vexing to evade buying a Canon EF 600mm f/4L IS USM Wonderful Telephoto Lens for $7200 to $12,000 dollars!!!! I'm unshakeable it's not as positive as a 7200 dollar lens, but it's way cheaper. I have against this tender held with an IS lens, but it does way greater with a tripod over desire distances. I against this with a canon 70-200 mm f/2.8 L IS. The shutter zip in day encounter decreased from 1/4000 to 1/2000 at f/2.8.

I just bought panasonic HDC SD-100 and some Kenko conversion lenses for it but when I put them on they appear.?
Q: ...in the edging around the edges, has anyone else had ths problem, am I doing something dumb? is there a simple soultion, or can anyone explain me abou some lenses hat do actualy fit this camera, telephoto and wide angle, give you Jack
A: These are use lenses and what're you're seeing is called vignetting.
About the only way to get rid of the vignetting is to zoom lose with your SD-100 to get rid of the dark frame edges.
You're most likely to see this with the sizeable-angle conversion lens.
Your camera really wasn't expected like an SLR to add lenses, so this is pretty much normal.
EX lenses and accessories on Canon Digital Rebel XT?
Q: Hi,
Can someone have an effect me if I can use the following accessories from an old SLR camera on my new Canon Digital Rebel XT?
1. Canon EX, 50mm, 1:1.8, with mounted Kenko 48 Skylight weed out and leather case
2. Canon EX, 35mm, 1:3.5, with mounted 48mm Skylight drip and leather case
3. Canon EX, 125mm, 1:3.5 with metal sunshade 125mm, leather chest, and mounted Hoya 72.0 S Skylight (1A) filter and if it happens
4. Canon close-up 450, 48mm screw-in, and directions-for-use folder
5. Sunpack GT20, Gold ingots Tube Solid State Electronic Flash Element
Thanks.
A: Wow, Canon EX lenses! I place of safety't seen any of those lenses in years. They are only made to put on the Canon EX camera and won't fit on any other manual focus 35mm bodies or any of the autofocus 35mm or digital cameras. Pitiful.
BTW, don't put that flash on any of the newer Canon cameras either. The high voltage on the shoe could harm the camera's electronics. It was a real common problem when the AE-1 cameras came out in 1976 or 77.

What third party brand digital lens are of good quality?
Q: What are the top third social gathering brand lens good of good quality from the subsequent (non Nikon or Canon):
Quantaray
Sigma
Tamron
Tokina
Kenko
Vivitar
I'm a Nikon Blur girl recently turned Canon Digital and I don't cognizant of about those non Nikon/Canon lens. The Nikon was given to me with Nikkor lenses so I never bothered to offer out into third party world. I've always bought the same brand as my camera-lenses.
If you have used any of them, castigate me what you think.
My two film nikons were from the 80's and early 90's. I switched because my cousin was frequently asking me to borrow my equipment and never return it. Since she got a Nikon DSLR, I figured it would fringe benefits me to get a Canon so she wouldn't ask me to borrow my lenses once I started buying them. Also, most of my friends use Canon and I got utilized to their cameras. To my dismay, my cousin won a EOS-1D Mark III in a photo trial. I'm planning to stick with the same brand name as my camera, I was just wondering how out of harm's way it was to venture out into the other lenses.
A: I'd stop away from Quantaray.
The rest might be a lens by lens quintessence of thing. Example the Sigma 24-70 seems to be ok but the Sigma 120-300 f/2.8 seems to have issues.
