Pentacon giant... !

    I have spotted a Pentacon 300mm f4 in a local store for £40, should I get it for a mixture of wow factor, rarity, uber-tele-goodness or shall I leave it alone?

    I have seen one good review of it on a Pentax/Praktica users site as a worthy lens in its price/class but otherwise not a lot of info!

    At least I will be able to photograph a mosquitos testes at long range!


    p.s. Damn, it comes in at 2.2kg and focused out is a whopping 300+mm long!!!!

    p.p.s. Better get to the gym and excercise my camera arm, oh and get a stronger tripod!


    p.p.p.s. Does it retain it's full f4 once mounted on a Micro 4/3 body? I assume it will!

    Why are you even asking that question?
    You know you want it...!

    Yes, I am just asking for support rather than advice!

    I want it for the 'my ones bigger than yours' factor! :rofl:

    But also wondering just how useful it would be as a distance lens for my Nature/Zoological shots.

    To answer your question, yes f4 is f4 regardless of what camera it's mounted on. However, DOF at f4 will not be the same as it would be mounted on an APS-C or FF camera.

    It's a large lens, but it's pretty cheap to get a 300mm, and it is Pentacon (Zeiss, although this lens is technically made by the subsidiary Meyer, according to google). With that focal length anyway, you'll want to use a tripod or monopod. I say jump on it. It will work wonderfully for your nature shots.

    At £40 it's a steal. But you knew that already. :wink:

    This site may help convince you:

    Got it!

    Just called the shop and paid by card, it is mine!


    As if I needed convincing!


    Just wondering if it is possible to get other mountings for it, as the mounting tunnel/funnel removes, presumably to allow mount changes!

    Just to clarify, DoF is a property of the lens. The DoF of a 300/4 is the same. However, since it is mounted on a m43 camera, it acts like a 600mm lens in terms of angle of view, but DoF-wise it does not act like a 600/4 in terms of DoF.

    At 400mm (600mm EFL) you generally do NOT want shallower DOF than what you get at f/4, which can be very shallow indeed. You want faster lens speed instead, so mounting it on a Four-Thirds sensor is ideal.

    My only question is how the heck did you make it out of the store without that lens, long enough to ask us about it?

    many thanks!

    Ned; I had it 'put under the counter' so to speak!

    Sinner; I will post soon, in fact I may go 'quiet' for a few days as payday is coming and I feel a field-trip in the air!


    Only question is; which lenses are going with me this trip and which ones will have to wait?

    ^5! I do suggest a monopod for ease of use and transport.


    PS- So where are the pics already?
