1.4 converter wanted

Hi ....I'm looking to buy a 1.4 converter to use with my 300mm f/4 Nikon.
Is there any reason I shouldn't buy a Sigma which you probably know is less than half the price of the Nikon ?
...or even a Kenko...even cheaper.
...what are your views please.

thanks....Mike

i have a reason not to by the sigma.... its a sigma.... my convertor was used a handful of times, the quality was rubbish compared to not using it and just cropping the image in PS, so it went on ebay.

if you must have a 1.4x then get the nikon.

Mike - 'cheaper' is not the way to go... Sad

Any teleconverter - even a Nikon unit - will 'degrade' the quality of the original lens used.

I agree with Rick...

It has to be the Nikon matey. Smile

Nikon lens equals Nikon converter Mike.

I've got the 1.7 Nikon, steer clear of the 2x

Why steer clear of the 2x, on the right lens it is EXCELLENT.

Yes but quite possibly not on the 300mm f4. A 2x loses 2 stops, so on an F4 lens you would lose AF.

Mike, all TCs degrade the image to some extent, they magnify any flaws in the lens. If you want to retain AF then the 2x is out of the question.

One point often overlooked. Most lenses are not at there optical best wide open put on a TC this gets worse. To get the best out of a TC you will need to stop down at least a stop and that's a stop from max aperture with the TC attached. If you hand hold, which I believe you do - you then run the problem of having too slow a shutter speed . I use a 1.4TC with a 100-300 (effectively 140-420) at the 300 end it needs to be at least 1/420 sec you of course have the option of increasing ISO.

I would like to stress I only use the TC when absolutely necessary and prefer to leave it in the bag.

Strange my sigma 1.4TC stands up very well indeed against my canon 1.4TC - somuch so I could use either one and get a very comparable image from either - impossible to tell them apart once edited for display. Of course I will agree that the canon (and thus I also expect the nikon) has the edge in corner sharpness, but that is really only noticeable on fullframe bodies - crop sensor its not an issue

Tamron tc's are very good (I have one) though I understand the Kenko are as good.

Before you buy one, check out the Kenko Pro 300 range. They used to have excellent reviews and were actually compared very favourably with the Nikon TCs

Cheers Ian...I had actually considered the Kenko and tried one at Saturdays air show.
The shots were acceptable but how much more so with a Nikon TC...who knows Smile
