Stumpy 284 #2 August 5, 2005 Do a search on the Digital Rebel XT - its the name for the same thing in the states. I think a few people have them.Never try to eat more than you can lift Quote Share this post Link to post Share on other sites
pbla4024 0 #3 August 5, 2005 Of course I did search. I haven't find anything about Sigma 20 with Digi Rebels in this forum. Fido Quote Share this post Link to post Share on other sites

sdctlc 0 #5 August 5, 2005 A number of people including me with the 350 have a sigma 15mm. I am very happy with it. the only draw back was not being able to put a filter on the front but that has not proven to be an issue. With the conversion fator this puts it in the low 20's in terms of lens comparison to a 35mm camera.. A 20 mm will be about 30mm I would guess.... Scott C."He who Hesitates Shall Inherit the Earth!"

pbla4024 0 #6 August 5, 2005 I focus on WS flying, so I guess 20mm is fine for me. I found good references for this lens outside sport, but none from skudiver. Fido Quote Share this post Link to post Share on other sites
mwabd1 0 #7 August 5, 2005 I have a Sigma 20mm for my 20D, its a great lens for the money but it weighs more than the camera body..........I am getting a second top plate for my FTP so I can put it up top. Other than the weight it's a good buy and usually around 300 cheaper than the 14mm. Quote Share this post Link to post Share on other sites
skysurfcam 0 #8 August 5, 2005 I've got both, but I've never married 'em up in the air. My 350/Rebelxt is usually my "portrait" camera, so the 20mm only goes on the 20d, my landscape camera. However, it will work, with the following caveats... As a general lens, its pretty expensive, and just not wide enough. It's great in low light being a F1.8, but the 1.6 multiplier makes it a 32mm equivalent. Most tandem/rel camera use around a 24-28mm equivelent, which is around the same a PC101 with a 0.45. (note - massive generalisation!) Folks with lots of experience then to go even wider and closer. Personally I only use it either in really low light, or if I think I want to sit back a little... One upside of the Sigma 20mm is that you can whack a filter on the front, which you cant do with the sigma 15 or 14mm. On the downside its LARGE! Some options for lenses: Canon 10-22mm: Pro: Great range, not too much barrel distortion, filterable. Con: Fricken huge, F4.5 minimum. Peleng 8mm: Pro: Massive FOV, unique shots, low profile, cheap. Cons: Vignetting, gotta fly within docking distance, manual or Av mode, F3.5, no hood, cheap. Sigma 14mm: Pro: Rectilinear, 22.4mm equiv, F2.8, Auto or manual, much lighterb than canon 14mm Cons: Exy, unfilterable, medium sized, big hood Sigma 15mm: Pro: 24mm equiv, F2.8, not stoopid expensive, Auto or manual, same size as sigma 14mm. Cons: Fisheye, unfilterable, big hood. Zenitar 16mm: Pro: Cheap. 25.6 mm equiv. F2.8. Low Profile/Lightish, Did I mention cheap? Cons: Fisheye, AV/Manual, unfilterable, no hood,Cheap. Tamron ATX-pro 17mm. Pro: 27.2mm equiv, auto everything, not nearly expensive, filterable, Low barrel distortion Cons: F3.5, not light, can be hard to find. Big hood. Canon EFS 18-55mm. Pros:CHEAP, Cheap, cheap. 28.8mm equiv at the low end, auto everything, filterable.. Cons F-high, easily broken, zoom lens. Sigma 20m. Pros: Rectilinear(ish), FAST at F1.8, auto or manual everything, filterable. Cons: Heavy, Fat, narrow (32mm equiv). For shooting landscape on everyday dives my lensochoice with canon DSLR's has become the 17mm tokina atx pro. Its wide enough, filterable, robust, affordable, and hooded. Most people I've seen jumping DSLR's in Oz are just using the kit lens, but I think that will change over time. Just my opinion. C. Brother Wayward's rule of the day...

cj1150gs 0 #10 August 5, 2005 SkysufCam Thanks for the excellent lens review - it would deserve a separate thread! You prolly know CAnon's 15 mm F2.8. Could you please analyze this one...

skysurfcam 0 #11 August 5, 2005 Yup. Be warned. The AT-X-Pro works nicely with the the canon DSLR range. The ATX range doesnt. (Get it? AT-X-Pro good, ATX Bad...) I'd buy this one it it stays cheap enough... http://cgi.ebay.com/Tokina-AF-17mm-f3-5-AT-X-PRO-with-CANON-mount_W0QQitemZ7535280822QQcategoryZ4687QQssPageNameZWDVWQQrdZ1QQcmdZViewItem C.

Thanks again! The Canon 15mm is a very nice lens, but personally, I'd save the money and get the Sigma 15mm, just for financial reasons. From what I've read about the Canon 15 and from personal experience with the Sigma 15, they are as good as equal in image quality and speed. Quote Share this post Link to post Share on other sites
vdschoor 0 #13 August 5, 2005 QuoteIs anybody out there jumping such setup? What's your experience? If I were you, I'd go with what is known to work VERY well, which is the Canon 20mm with the Canon EOS 350D. The Canon 20mm is only 10 bucks more than the Sigma 20 (at least on the B&H website) Quote Share this post Link to post Share on other sites
psw097 0 #14 August 5, 2005 I've used a 300D with Sigma 20/1.8EX skydiving. Its a nice lens but big and heavy. It has nice color, contrast and resolution, I have a 20x30 in my living room shot with that lens with a film body. I thought it was a little too narrow on the digital for jumping and a bit too wide with film. Optically it was great but the autofocus was very slow and noisy. Also, I hated the push-pull clutch. I finally sold it for a Tamron 17-35/2.8-4. The Tamron is better built and even better optically but sacrifices a stop on the wide side. Quote Share this post Link to post Share on other sites
psw097 0 #15 August 5, 2005 A couple notes on the manual lenses - Zenitars. On the 300D and Elan series they don't stop down meter very well. Sometimes mtering would be perfect sometime it was all f'ed up. I don't know about the 350D. Also - a 15mm or 16mm 180 degree fisheye does not equal 24 or 25.5mm on a crop factor camera. Rectilinear to fish-eye is not a direct correlation. The FOV is what is cropped - 180/1.6 = 112.5 degrees. This is around 19mm. Details: FOV Quote Share this post Link to post Share on other sites
velocityphoto 0 #16 August 9, 2005 I bought a canon 15mm and i ended up trading it in for the 15mm sigma because of a fogging problem in the center of the glass,i believe due to the thickness and shape of the outter element. The sigma is great!and its $200.00 cheaper A friend will bail you out of jail , a REAL friend will be sitting next to you in the cell slapping your hand saying "DUDE THAT WAS AWSUM " ................

I've been jumping that since the day I switched to digital.. Quote Share this post Link to post Share on other sites

skysurfcam 0 #20 August 9, 2005 Pluged on onto my 300D, it wouldnt talk happily, locked up the cam, gave an error 99, also felt pretty cheesy to be honest. Then again, maybe I tried with a baddie. YMMV The AT-X Pro 17 hasnt had any probs. C. Brother Wayward's rule of the day...

garywainwright 0 #21 August 10, 2005 Had no problems with the ATX on my 350D - not quite as wide as i would like (looks identical to the 18mm end of the kit lens) but i like having a prime lens that i can put a uv filter on for protection - when you are as clumsy as I am its a good idea...http://www.garywainwright.co.uk Instagram gary_wainwright_uk Quote Share this post Link to post Share on other sites
