as a birder, i encounter probably the same problem as all,

my reach is too short many times,

as taking photographies is the main  purpouse

 

i currently have a canon 7d mark1,

and as longest lens a canon 400mm f5.6,

with kenko converters 1.4 and 2.0,

i alm quite happy with the 1.4, af still possible in very bright light, iq ok-ish,

less about the 2.0 one, no af of course, but iq is low end,

combining the two...no comment so

 

obviously i should upgrade to a ef 600 f4.0 or 400mm f2.8

but i fear  my wife would not say ... ¥€$...

 

so digiscoping ?

as my 400mm has a aperture of 77mm,

any smaller scope makes not really sence, or am i wrong,

 

3 options seem to be possible at this time, (accessories included)

 

1 a reasonable priced ed scope (which would cost me around 1500€ or even less)

2 a mirror one alike the celestron c5 (cost about a 1000€)

3 a canon 600mm fd f4.5 (cost about a 1200€)

 

i know this is not really a birder forum,

but i did not find really usefull information else,

 

any thoughts ,

 

...or should i change my wife....

;-)

 

 

kr,
