david_boily Posted December 6, 2004 Share Posted December 6, 2004 I just bought one of these lenses used from the net and although I had read that the build quality is not like L lenses, I'm still surprised at the movement in the front element. Just how much movement should there be? I'm thinking of taking it to Canon. Link to comment Share on other sites More sharing options...
bobatkins Posted December 6, 2004 Share Posted December 6, 2004 I'd give it about a 5 on the International Standard ISO WONKY scale. Yes, it moves around when zoomed out. Maybe 1/2mm? Link to comment Share on other sites More sharing options...
upe_vantonni1 Posted December 6, 2004 Share Posted December 6, 2004 mine is pretty loose but its not sliding all ove the place or anything. its just all the weight is definately in the front and it extends in two different pieces instead of one unified piece. so it just has a weird feel to it.

anthony_m1 Posted December 6, 2004 Share Posted December 6, 2004 Yes, mine moves too. From a build quality standpoint it is far better than my Sigma EOS lenses. It is a solid capable lens. Link to comment Share on other sites More sharing options...
stato19 Posted December 6, 2004 Share Posted December 6, 2004 If I may jump in here, mines moves around too. It doesn't seem to effect anything. All things considered its well built. I don't baby mines and I've never had a problem with it because of the movement. Link to comment Share on other sites More sharing options...
www.philwinterphotography. Posted December 6, 2004 Share Posted December 6, 2004 Mine moves too. I've never been impressed with the build quality or feel of this lens, but it's light, works wonderfully, and continues to surprise me with the quality of the images. Don't worry about the movement - just take pictures. Phil Link to comment Share on other sites More sharing options...
david_boily Posted December 6, 2004 Author Share Posted December 6, 2004 Thanks Bob, Actually, I measured the movement on my lens and it is closer to 1mm on the Wonkometer. Link to comment Share on other sites More sharing options...
phyrpowr Posted December 6, 2004 Share Posted December 6, 2004 Yeah, mine slops around, plasticy build, not an "L", zoom creeps, more than 15000 total shots through it, on four different cameras, desert, beach, alpine 20-100 degrees pix are great film and digital and I ain't lettin' go of it.

JosvanEekelen Posted December 6, 2004 Share Posted December 6, 2004 Mine moves a bit as well, but opposite to Bob's observations it moves more when zoomed in than with zoomed out. Just take some pictures in order to test it, thats what the lens was made for. Link to comment Share on other sites More sharing options...
erick_kyogoku Posted December 6, 2004 Share Posted December 6, 2004 I have one of these lenses and it was so wonky that it ended up taking <A href="http:// www.ocf.berkeley.edu/~hiro/france/pretty-paris/ ">these photos</A>. Now if only I had a lens that didn't creep, I'd take much better photographs . . . Link to comment Share on other sites More sharing options...
jtek Posted December 6, 2004 Share Posted December 6, 2004 Erick, those pictures are just great! Maybe I need some wonky lenses. Link to comment Share on other sites More sharing options...
andrew robertson Posted December 7, 2004 Share Posted December 7, 2004 What's all this talk of creep? My 28-135 IS doesn't creep a bit. In fact, it's the most creep- resistant zoom lens I have ever used (for zoom lenses that aren't constant length). I'd again like to introduce my theory that there are secretly two versions of the 28-135 IS: a 'creeper' and a 'non-creeper'. Link to comment Share on other sites More sharing options...
jespdj Posted December 7, 2004 Share Posted December 7, 2004 Andrew, how old is your 28-135? Mine wasn't very "creepy" when it was brand new, but got "creepier" after a few months. It's normal that the 28-135 is a bit wonky. The build quality is not great, but the optical quality is good (many people regard it as Canon's best consumer level zoom lens in that regard) and it's very versatile.

les Posted December 7, 2004 Share Posted December 7, 2004 Wonky. Takes good pics though. So, not too wonky after all... The degree of wonkiness can be assessed as about 0.5-0.7mm range when extended to 135mm. Can't provide any better info, my wonkometer is out of whack (or should I say it is whacky ?) The degree of whackiness of my wonkometer sadly is not known ;) Link to comment Share on other sites More sharing options...

J.W. Wall Posted December 7, 2004 Share Posted December 7, 2004 Mine slips a little, too, but the pix are good. So, has anyone discovered a method of dewonkification? - John Link to comment Share on other sites More sharing options...
david_boily Posted December 7, 2004 Author Share Posted December 7, 2004 Well thanks everyone for your responses, I feel that my lens is probably within tolerances (-1 to 0.75 Wk/mm). For those who are curious, the wonkometer and the wonky scale were invented by German watch maker, Baron Dieter Von Wonkburg. Although his watches were some of the most beautiful timepieces made in the 18th century, the couldn't tell time for S$%t. Apparently Baron Von Wonkburg suffered from arthritis and as a result he had trouble tightening the screws of his watches. Well, within a short period of time, the mechanism inside would loosen and stop working, sometimes coming apart all together. As a result people began reffering to anything loose of out of adjustment as "Wonky". I OK I made all that up, but damn if you didn't get right away what I meant by is your 28-135 wonky!

johng Posted December 7, 2004 Share Posted December 7, 2004 Maybe I don't understand the the cocept of Zoom Creep or maybe I am not as lucky as the rest of you. I have the 28-135 lens and have little to no creep when I hold the camera/lens parallel to the ground. However, If I am shooting vertically down (toward ground) and have the lens zoomed toward the wide end, the lens creeps all the way toward the telephoto end. If I am shooting vertically up (toward sky) and have the lens at the telepgoto lens, the lens creeps all the way to the wide end. This is a lot more than a few mm and has been a major source of annoyance. If I am shooting subjets that don't move, e.g. still life, I use a piece of gaffers tape to hold the zoom in place. This is the only real issue I have with what is to me a very good walk-around lens given the price. Link to comment Share on other sites More sharing options...
erick_kyogoku Posted December 7, 2004 Share Posted December 7, 2004 Thanks John! I took these wonky photos in <a href="http://www.ocf.berkeley.edu/~hiro/italia/cinque-terre/">Italy</a> using the 28-135IS. I also used a consumer 24-85 when I was in <a href="http://www.ocf.berkeley.edu/~hiro/tibet/">Tibet</a>. I think these lenses can take very good photos... But my next lens will be a 17-40L, probably in the coming months. Link to comment Share on other sites More sharing options...
