Look for a lens for an S2 rental >300mm

Andrew Ling said:

I've renting an S2 pro but they're out of > 300mm lenses, so I'll
have to buy one. It's a good buy since I'll be able to use it with
Kodak 14n rentals later also. Would prefer to spend around $500
for a zoom lens. VR is a plus too. But is VR really needed for
handheld sports shooting? So far the best bet looks like the
80-400mm VR but the cheapest i could find it is $1300.

Hi Andrew,

The 80-200 f2,8 and 300mm f4 are also very good and sharp lenses
for using with the S2, some friends of me bought second hand lenses
and they are very happy with it, try maybe to find a second hand
lens (in shops or the net).

With very kind regards,

Dirk

• You lose 2 fstop, meaning you get a shutter speed 4 time slower.
• doubling the focal length is like getting a shutter speed 2 time slower.
• It is like having to shoot 8 time faster to get the same image freeze (4 x 2 = 8).

• You lose 1 fstop, meaning you get a shutter speed 2 time slower.
• Increasing the focal length by 1.4 is like getting a shutter speed 1.4 time slower.
• It is like having to shoot 2.8 time faster to get the same image freeze (2 x 1.4 = 2.8).

Hi Andrew,

At 900mm (2X teleconverter), you need to shoot at least 1/1000sec
handheld and f8. That is a lot of light you do not have outside in
a shadow .. You will need a tripod for sure.

Regarding the camera shake point of view ..

Adding a 2X to a lens means :

• You lose 2 fstop, meaning you get a shutter speed 4 time slower.
• doubling the focal length is like getting a shutter speed 2 time

slower.

• It is like having to shoot 8 time faster to get the same image

freeze (4 x 2 = 8).

Adding a 1.4X to a lens means :

• You lose 1 fstop, meaning you get a shutter speed 2 time slower.
• Increasing the focal length by 1.4 is like getting a shutter

speed 1.4 time slower.

• It is like having to shoot 2.8 time faster to get the same image

freeze (2 x 1.4 = 2.8).

Maybe a 1.4 teleconverter could do the job.

• That is the way to do. The resulting Focal Length is 900mm.

• Yes

• The 80-400 is a f4.5-5.6. Pretty dark. This means no AutoFocus with the 2X and a lot of focus hunting with the 1.4. I would say 2X upto f2.8 and 1.4X upto f4.

Hi Andrew,

I;m not sure if it's proper but i included the 1.5 Focal length
multiplier to arrive at the 900mm. Just a 300mm lens a 2X extended
and the multiplier.

• That is the way to do. The resulting Focal Length is 900mm.

Do you still think it would be best to go with a 1.4X extender?

• Yes

What about w/ VR? The 80-400 VR lens would then me 1200mm.

• The 80-400 is a f4.5-5.6. Pretty dark. This means no AutoFocus

with the 2X and a lot of focus hunting with the 1.4. I would say 2X
upto f2.8 and 1.4X upto f4.

The Sigma teleconverter are very good by the way.

Try it before you buy to make sure it does what you expect.

Yet the same rental store actually has a used prime 300mm F4 for
$600. I'm not sure if I can shoot clear pics at 450mm or 900mm
with a 2X convertor without a tripod or VR, though. What do you
think?
Also I prefer a zoom lense over a prime for greater flexibility.
