    Default Kingfisher with food (stacked converters)

    Attached Images Attached Images
     
    1D Mark II, Canon 500 f4, x2, x1.4, 1/250, f13, tripod, full Wimberley, hide

    Got this a few years ago in Israel. I always wonder what is the best way to go - get the shot with stacked TC and not having to crop OR using shorter focal lens to avoid using the stacked TC and then crop.
    Same issue when using the x2 converter against not using one and then crop....:2

    When using TC it is very important to stop down. Focus was done manually but I think the camera will confirm when getting the focus.
    Keeping in mind this was taken with the Mark II - results with the Mark IV should be ever better.

    great light and sharpness is excellent as presented, love the BG and light f/13 helped keep things inside DOF.

    Of course image will look sharp with stacked converters when presented at 1024 pixels but when you blow up the RAW even with a single 2X TC sharpness is never satisfactory to my subjective eyes . For me the limit is 1.4X, if the bird is too far I'd just try to get closer if possible, if not I try another day

    Also the problem with newer sensors is that they will be diffraction limited at f/13 so stopping down doesn't improve much...

    Very nice Ofer - the colours of this species look great here. That cricket is having a bad day!

    Thanks guys!
    Arash, I have actually printed this BIG a few years ago and it looked very nice. Keep in mind this is the Mark II...
    As you know, my standards when it comes to IQ are pretty high but sometime you won't have another chance and you will need the reach.
    As to using the x2 TC - I strongly disagree with you. I got some very nice photos with the x2. Of course it is always better to avoid using TC when possible but in real life this is not always possible.
    BTW - this is why I find the Canon 800 f5.6 such an attractive option...

    I agree Ofer this one should print nicely, I have some shots with the 2X too, I used Doug's 600 with 2X when we were shooting kites, one of the most skittish species here in Cali and one that you always lack reach, the photos came out nice and sharp, prints look good too, but if you inspect them at 100% they are not that crisp. My point was I wouldn't do it unless it was a life bird and I wanted to get a shot at any cost...
    anyways, this is a great shot.

    Another thing to consider is that you will use the x2 TC or the stacked when your subject is far. Image quality will also suffer because of the distance and atmospheric factors involved. When you use it from a short distance like in here IQ will suffer a bit less.

    Great capture and impressive sharpness, especially with stacked TCs...there is even detail in the grasshopper wing!

    Excellent IQ and sharpness Ofer, with good details and colours on the KF. The grasshopper in the beak puts this over the top. An opportunity well used.

    Hi Ofer.....
    You do what you have to do...when you have to do it. I love this one and for here....it's sharp. We each need to judge the quality based on our own standards and what our intended output is of the image. I don't print so I can certainly get by with occasional stacked converters. I probably only have 5 or so images that were good, but for me....I was thrilled. Now as to the 2X.....it's probably a standard attachment on my 500mmL IS. That may change if the new 600mmL IS comes out in my lifetime. Well done with a beautiful bird and a great lunch item.

    Impressive!! Hard to see lost detail with the stack TC's. Grasshopper adds nicely.
