    Canon 7d mkII

    Better low ISO performance would be a start!

    Which 1.4x converter should i buy

    There is no such thing as a free lunch.

    Sensor cleaning.

    I clean my sensor about once every 6-8 weeks. I use a rocket blower and a lens pen. Most of the time it works a treat, I reckon getting it "pro" cleaned with wetwipes or whatever is a swizz. In this country where we all shoot at f2.8 and f4 it has to be supremely dirty to be noticeable. In...

    Full frame query.

    I think this discussion basically gets us to a place where the camera operator is the limiting factor and not the camera itself.

    Full frame query.

    My comments were in reference to FF cameras that were not a 1DX. Ie if the 1DX were completely out of the question (as is the case for the vast majority), what would be next in line? As it is, the 1D4 does me just fine and I don't see a 1DX necessarily improving my output. And I am also sure I...

    Anything anybody writes is an opinion. That's what makes life interesting. As for calling people's images junk.... well I see what you mean re subjectivity, but I've tried constructive criticism a few times and people just don't want to hear it. Possibly it's precisely because of subjectivity...

    I just came back from Morocco, it was wonderful weather.

    Full frame query.

    Without wishing to have this thread descend into yet another "all the gear" monologues, this is the reason why big twitches can be so farcical these days. Every T D & H has a massive bloody camera, and there's a massive scramble and often pathetic behaviour as they all want the money shot. That...

    Best photographer I know uses a 1d3 and puts most people who use a 1dX to shame. It ain't all about the gear folks.

    Teleconverter compatibility

    Don't even bother using ANY converter with the 55-250, you will not be happy with the results, those types of lenses are just not designed with TCs in mind. Jonathan

    Canon 1d mk111

    I think the 1d3 focus issues only manifested themselves in certain uncommon situations, not as a matter of course. I'd look at MA in the first instance. Or of course technique, as lack of sharpness is mostly due to operator error.

    400 f2.8 and 500 f4

    Interesting lens with which to acquire basic skills!

    Grading Photos

    Unless this is tongue in cheek, I'd respectfully suggest that this is the absolute minimum, and that it is far from job done. I recently spent some time thinking about my own decision-making process, and I came up with this which I attempted to illustrate what I meant. I still have heaps to...

    7D vs 70D for Bird photography

    I'd pick the venerable 1D2 over either of them, half the price, and in general many times more capable!

    New 400/5.6 getting hard to acquire in places!

    I don't think that any bird photographer who cares about IQ will give a rat's arse what the lens looks like on the outside or to the outside world. It's a tool, nothing more. I agree that the cost of the newest large lenses is prohibitively expensive, the older Mk I lenses represent far better...

    New 400/5.6 getting hard to acquire in places!

    Fine, enjoy your soft photos.... The current 400mm is approx 1.2kg I think, physics would suggest that the Tamron will be significantly heavier. And not remotely as good.
  17. jalethbridge

    What Landscape lens

    Yeah, it's a bargain, and takes 77mm filters same as many canon f4 lenses.
  18. jalethbridge

    New 400/5.6 getting hard to acquire in places!

    I completely disagree. Any lens that is even a bit soft at the long end is a complete non-starter. Don't care how cheap it is, or how much more a Canon L is. You buy something that can't take a sharp picture and you have thrown your money away. I would buy a 400 f5.6 IS in a heartbeat, it would...

    Have 7d, but so confused over lens...help?

    the 400 prime has zero tendency to do this

    Back to basics

    My advice is to get low, get close, stick your camera in "M" mode and go from there.

    Advice on monopod and heads

    I disagree that a tilt head is necessary. Adds weight and instability, and if you're doing things properly you'll be want to be more at less at the same level as the bird and thus have no need for any extravagant amount of tilting. Just get an Arca clamp like those made by Kirk or Wimberley...

    Changing to Canon Advice

    I use top quality canon gear and believe me, I still delete crappy flight shots all the time. Don't blame the gear, blame yourself!
  23. jalethbridge

    flight shots - what would you use?

    400 f5.6, no question. Light and fast. a 300 f2.8 is another option, but a lot heavier and pricier
  24. jalethbridge

    200-400 f4 1.4x at last

    It looks brilliant, but you can get the world's best 500f4 for £4500 less.

    Macro lens advice price £500-700

    It's a great little lens and can be used for a lot more than just Macro to boot.
