Well I'm mightly impressed with the Canon 2x extender especially when connected to the Canon70-200 f/2.8L.
I have what I think are some super shots with this combo. However the quality of this lens combo was brough home to me a few days ago. I saw this high flying airliner Lufthansa 747 over flying us at 35,000-40,000 ft. I liked the way the sun was illuminating this airplane so i fired of a couple of shots.

Harry those shots are superb.Very good.I do have the 2x but only use for something special if I do not have my digiscoping stuff with me.I do not take a tripod with me unless I am using the scope,and it is virtually impossible to hold the lens steady whils't trying to use MF .At least the 1x4 uses AF,providing the pins are taped,makes things so much easier.

Thanks Christine, yes I can well image the dificulty trying to manually focus, especially if you are referring to the 100-400mm.
I considered the 100-400, but in the end went for the 70-200 f/2.8 + 2 x extender, so that I would retain auto focus. There are a few times when I wished I had the 100-400 + extender, but on the whole I'm very happy with my choice. To be quite honest I was amazed when I saw the vapour swirling of the wing tips on the cropped version, especially when you consider the aircraft was approx 7 miles away. Harry |

Love the aircraft shot.
Anybody have any experience of comparing the old Kenko 1.4 Pro with the new ''digital'' one which has coatings on the rear element to reduce reflections off the sensor. Is there any discernable difference in the real world? |

Further to my test with the 400mm f.6 and 1.4 tc I tried some shots today with an old teleplus 2x converter. This gave me a focal length of 800mm at f11. Used a tripod and manual focus. Must say I was pleasantly suprised at the IQ. Never tried it before with this combo as I had always read that 2x tc are a no go.

Excellent Roy, I haven't tried the 2x, I may give it a go and see what the results are like.

Roy,those shots are great.I guess I will have a go with the eiders out in our bay,difficult to digiscope,esp with the wind,also the light from the sea,but using a tripod,may manage a reasonable shot.Did you use any other settings other than manual focus.Just set to F11,and MF.That means using the AV mode,I think.Which ISO setting did you use,Roy?. I usually pick 400 ,hoping it may compensate for loss of light stops(I think that is correct).
