That's exactly right Mike, Im not sure if the Kenko will but I doubt it, one reason for me buying the Tamron 70-200mm instead of the Sigma one.
But at 500mm it will do me for a while, it will have to now broke.
Well I tell a lie, Tel is picking up the Sigma f5.6AF 400mm on Saturday, and I sold my compact (bridge) on Ebay.
so just a few more lenses to go on Ebay and I will be solvent again.
How do you get on with the 135-400?

Well, I did go to the NEC for the show , I also wore the Pentax “base ball” cap, yes I did get one or two funny looks.
But this years “show” was to say the least unimpressive, no where near as good as previous ones.
Loads of bodies milling around, very few good bargains to be had not even any “goody bags” going, Nikon ran out of brochures, I had to get one for a friend, not for me !
The Sigma stand was busy , I wanted to see the 150-500mm.
The usual big ones were Nikon/Canon/Olympus with Epson /Fuji and a couple of others.
If I go next year will depend on if Pentax decide to go.
I feel it is about time for Hoya to spend some money on good camera/lens development and then on advertising, after all they are one of the larger companies in the photographic world.
So Hoya, please don’t let the best and one of the oldest marks down.

Hi, welcome to the forum

Hi Mike, he does look good, and perhaps you coming back to the UK will give us the summer we missed last year.

Hi all, Tel has bought the 400mm so now gone.
Thanks for all the interest.

As to weight, 0.893kg or 1lb.15.5 ozs
It does autofocus with the TC (in good light)as to quality have a look in my gallery at the helecopter shot.
It is quite a rare lens, there are a few manual "A" lenses about, this one not many, and the "APO" version like rocking horse poo! only because it was a very expensive lens, My version is "Battle Ship" grey I have had a filter on it all the time, I am hoping for offers around the £120-£130 mark, it is in very good condition optically, and bodily, I do look after my kit.
Ps it does have a tripod mount on it.
The shot is the first one i posted

Hi Amin
Hosed down and smelling fresh!
The 300mmDA* is a very fine lens and prime lenses should be, when shooting wildlife you cant always be in the right place that is why a zoom is used.
Now if you are doing motor sport etc the prime may be better, you make sure you are in the right place for the focal length.
Up until now most wild life shooters who had the money went for the 50-500mm EX lens.
But I am what i call a "happy snapper" if i see something I want to be able to shoot almost instantly, and maybe this lens will help.
The Chairman of our local camera club may take 10mins to setup a shot with his Nikon gear he has to cart loads of kit around, me I prefer to have my bag, mono pod camera, lenses spare cards and batteries.
I have a Sigma 400mm AF 5.6 prime that gets used about once a year Ideal for the Aircraft enthusiast, and it works with the Kenko 1.5 TC,That is quite light, it will be going on Ebay soon with several other lenses that i seldom use, I have to make some money to pay for my new toy
