ivan_ping_ching_cheng Posted June 18, 2003 Share Posted June 18, 2003 I own a Sigma 17-35 f/2.8-4 HSM EX. I am pretty disappointed by itsperformance mainly because of its severe loss of light and blur at theedge and corner even at f/5.6-8!! I am considering the new 17-40 but most reviews and comments I canfind on the web are mainly based on DSLR, which 1.6x factor cannotreflect the quality of the edge portion of a picture. Did anyone usethis lens with a film EOS? How's its performance and does it have myaforementioned problems (loss of light and blur at the corner)? Thanksin advance.

lex_bowden Posted June 18, 2003 Share Posted June 18, 2003 Hi there Ivan, I've had a 17-40mm for a few weeks now and use it on an EOS 3. I mostly shoot slides (provia 100F) and have been very impressed with the lens. I have also used a 16-35mm L f2.8 and found that at f4 the new lens is every bit as good...the contrast actually seems a little better. There is a little distortion around the edges at 17mm (but you would expect that) and is probably why you want a very wide angle zoom anyway. I am very impressed with the lens and had I not already had one, I would certainly go out a get one. If I could have either the 16-35mm or the 17-40mm, I would take the 17-40mm. One thing you will have to factor into the purchase price is the cost of some form of filter to fully 'seal the front of the lens. The front element of the lens goes in and out a little when zooming and the filter just seals off this movement from the outside world. Great lens, you will be happy with it.

beauh44 Posted June 18, 2003 Share Posted June 18, 2003 Hi Ivan, I have the 17-40 f/4L and have used it on both my EOS 1V as well as my 10D. I really like it and it's quite a bit less expensive than the 16-35 f/2.8L. It has a very useful range on both cameras. I've found corner sharpness good, very little flare, and all my pics with it have been sharp and contrasty. It doesn't quite hang with my 70-200 f/2.8L IS in terms of sharpness, but not too many lenses do. I give it 2 thumbs up! Best wishes . . . Link to comment Share on other sites More sharing options...
rendy_setiadjie Posted June 18, 2003 Share Posted June 18, 2003 Ivan, I'm just purchased 17-40 mm f/4L to be used for my EOS 3. Comparing with 16-35 mm f/2.8L & 24-70 mm f/2.8L, 17-40 mm results are darker than the other 2 contenders on 17 mm until 35 mm where all lenses overlapped. The results that I get from 17-40 mm are great even above 28 mm range, the pictures are bit softer than 16-35 or 24-70. Hope this will help.. happy shooting ! rendy Link to comment Share on other sites More sharing options...
ivan_ping_ching_cheng Posted June 20, 2003 Author Share Posted June 20, 2003 Thank you all for your valuable comments!! I have just bought it yesterday. I have used the last few slides in my camera to test it out. Comparing to the pic taken by Sigma 17-35, those by 17-40 seem a LOT sharper. Link to comment Share on other sites More sharing options...
