Teleconverter 1.7 attached to 70-200 VR - comparison shots

[Glen]

Hi all, a few people have asked for comparison shots with the 1.7 TC. Here a few quick shots I got off this evening, all taken from a tripod with remote, using auto focus in AFS mode. In normal portrait fashion, the focal point was the eye, in this case the left one. The subject is relatively shiny, so hard to take a good shot of, but with lots of different surfaces. I was about 6 metres away, so DOF was relatively small, especially as many shots were taken wide open. I am a bit unsure of methodology, so compared the TC wide open (F4.8 ) to the bare lens at a similar F stop and also at F2.8. I am not sure what is a fair comparison and welcome suggestions. If anyone want different comparisons feel free to ask or if you want NEF's or full sized JPG.

No sharpening at all was applied, these are resized for the web and exif should be intact.

Just realised these were a bit small, can email any comparison shots

I presume Glen that these shots were taken at your home - after seeing that head I now know why you go out a lot

[Glen]

Yes Chris, taken at home. I like the head but I am about the only fan. I point out to the girls it is quite disrespectful their attitude to the head.

That head is your guard, perhaps

[Glen]

Birddog, that is how I view it. The last owner made the ultimate sacrifice so I could use his head, it would be disrespectful not to

[Onyx]

Glen, thanx for taking the time and energy to shoot these images. I'm sure some here will appreciate your efforts.

Is that the head you talked of at an earlier meet (ie. real human skull)?

[Glen]

Onyx, thanks they are also on my pixspot account. Yes, that is a real human skull which is why the wife and daughter don't like it. As I pointed out to them, way too late to give it back now.

Glen,

I tried to look at your pics but quickly noticed the brick wall even though you had tried to disguise it by adding a coat of paint.

I just cannot bear the wall.

Cheers,

Darryl.

[Glen]

Darryl you caught me out!

[christiand]

Hi Glen,

is this a Tibetan skull ?

What is the purpose of it ?

Cheers

Appreciate your effort here Glen. One thing I noticed was some colour differences when the TC was applied .... noticably between:

120 @ 4.5 and 120 with TC @ 4.5 when you shot the chillie bush

and

200 @ 4.5 and 200 with TC @ 4.8 when you shot the chillie bush

didn't notice much isses with sharpness - looked pretty good.

Thanks,

[Glen]

Hi Christiand, well picked it is a Tibetan tantric skull, used in many ceremonies to ward off wrathful deities. It is believed that the best skulls come from one who has died a violent death, were a wise person, died prematurely young, etc. A person who dies peacefully in their sleep in old age is not considered a very usefull skull. I bought in a market in Kathmandu, everything in the market was under $2-3 , then this one skull was $100. Wouldn't negotiate, telling me it was the only one he had, ended up buying it (was with a mate of mine who was a doctor, confirmed it was genuine), came back 4-5 days later and there was another one! My doctor mate bought it.

[Glen]

Chris you're right! $1250 or $1200 US, maybe my guardian really is a new lens! I love the description on the second one where they describe the item as "new". By definition a human skull must have been used at least once before As you know Chris I am always happy when I get a bargain

[sirhc55]

Glen you must know by now that there are those that never use there skull

[Glen]

Glen you must know by now that there are those that never use there skull

Surely everybody headbuts when fighting?

So what do you think Glen of the TC1.7 for crispness with the 70-200VR?
I'm in two minds as to get the TC1.4 or the TC1.7, I know the TC2.0 is shite.

[Glen]

Kipper very happy with it, would recommend it, especially at the F1 if you are a long way away. 1.4 is better, but reach is reach. Could also be used later on 300 F4 AFS, to give a cheap big gun
