    Default canon 100 400 vs sigma 50 500

    Hi All,

    I'd appreciate some advice please!

    I'm trying to work out if I should replace my Sigma 50 500 OS lens with a Canon 100 400 L lens. I'm finding a lot of my shots soft, particularly when cropped. They sharpen up ok in Lightroom etc.

    You can see some of my shots here: viewtopic.php?f=10&t=8452 and here
    viewtopic.php?f=10&t=8452

    I know the L series lenses are great and it seems to be a popular lens on this forum, but I am wondering if it's

    * poor technique - I've read up on long lens technique, I'm using a tripod etc, have tried mirror lockup etc
    * unrealistic expectations - is it unrealistic to expect sharp images with that much crop? Personally I don't think so, but I'm still learning!
    * Blaming the lens - maybe it's me!

    If you look at this shot by Richard - viewtopic.php?f=9&t=8575 it appears tack sharp.

    Now compare the images below of the same species - no where near as sharp! Original and the cropped and processed version.

    Dave--I used to shoot with the 50-500 and have also used the 100-400. The 100-400 is definitely better. Whether it is that much better to justify spending the money on it, I don't know. I went from the Big,a to the 300 f2.8, I wouldn't see the difference in quality between the two zooms as something worth pursuing in the long term. However, if you need a zoom lens, the 100-400 is probably the best in the category (until Canon release an updated version of that lens which is sorely needed...)

    Thanks Tobias, your comments are appreciated. If I were to switch to the Canon 100 400, I'd sell the Bigma, so hopefully the change over cost vs performance works out.

    Anyone else have some thoughts?

    I feel it's to big a crop...? IQ will suffer even with a canon at this range IMO. Mike

    I'd agree with Mike's assessment that it is a big crop. Richard's photo of the Superb FW was taken from a distance of about 5m. I'm willing to bet that yours was taken from about twice as far, possibly with lens at max. zoom. Under those circumstances you have everything stacked against you.

    I use a Canon 100-400 which I purchased as a compromise because I do not use it exclusively for bird photography. I have been very happy with its performance.

    If birds will be your main subject, then you should seriously consider one of the primes; 300/2.8 plus converters (as suggested by Tobias), 300/4, 400/5.6 or 500/4. I cannot comment on these but many of our forum members use them and could offer first-hand assessments.
    Cheers,

    George

    Thanks George - yes you're right, it was taken at 9 metres.

    That's a good point about the 400mm prime - it's roughly the same price. It lacks IS though. Hmmmm...so much to consider.

    Looks like too much of a crop for the 550D to handle Dave. Even my full frame 5D would have trouble with zooming in on the original that much. I'd also recommend upgrading from the Sigma. Its a lens that most people end up feeling limited by and the 100-400mm L is a great option.

    Dave i wouldn't ever judge a lens by a crop of this magnitude. If you have to crop this much I'd work on getting closer rather than a new lens. Even using a 1D and 500mm f4L I wouldn't expect anything usable

    Thanks everyone. I'll go out this weekend and try and take some closer shots and see how I go!

    If you have a filter on the lens try taking a shot without it. They sometimes cause problems.

    Doug is absolutely right, filters will cause all sorts of problems with sharpness and contrast. If anyone is using filters on their lens then have a look at the article on "filter fables" on my website.

    Yep filter is already off.

    Thanks again to everyone who has provided comments. I very much appreciate it! As a beginner I have learnt a lot from just this thread!

    Are there "getting closer" techniques or resources I should be looking at? (I'm going to google it now)

    Dave have a look for starters at Margarets very recent thread on camouflage.
    viewtopic.php?f=21&t=8572
    Also have a look through the other Techniques & Educational threads - i reckon you will find a heap of info in there with a small amount of searching

    I find at 500 my 50 to 500 (without OS) does great shots close up particularly when I hit it in conjunction with a flash. Beyond 50m I am very disappointed with 500mm. I think with my lens it becomes soft between 10m and 50m. My friends with canon 100-400 seem to take better photos of more distant subjects at the long end.

    Thanks again everyone for your comments. As a beginner I'm learning a lot. I think what everyone has said so far is pretty much spot on. While doing some research on focus tests, I learnt that the human eye is very good at picking up out of focus text - hence why many focus charts use text! So I set up the sigma 50 500 on a tripod and focussed on some text from about 10 metres away ( the text on the oven knobs in the kitchen!). It comes out very clear and only starts to get a bit fuzzy when I zoom in on the computer / crop *A LOT*. So it's not really the lens so much, but more to do with technique and unrealistic expectations on my behalf.

    I'm still drooling over Canon L series glass though....
