    As in topic, is there any 400 or 500mm lenses with low F-values that i can adapt to my M43?

    I have a 400mm but it´s 6,3.

    The lenses do exist, but they tend to be huge and quite expensive. Nikon's 400/3.5 is 2.8kg and costs >$1k, and they only go up from there. What exactly do you need such a long lens for?

    This is the realm of big white enormo-lenses and price of a car efforts.

    I was hoping to get a older manual lens that wouldnt cost that much, since the one i have are quite small, i was hoping there would be lenses that are from the 70-80s that was bigger to get better lightvalues.
    I could about pay a few hundred dollars, and i would like to use them for wildlife photo.

    the FD 300/ 2.8 would cost you less than 1K but
    that's about it..... you are seeing current prices
    unless someone simply doesn't know what they have.

    Here is my 300.....

    4441592802_72f73b8f45_z.

    which I may sell if I spring for the FD 500/4.5

    What sort of wildlife?

    Handholding a 400mm lens with 2x magnification is very difficult, particularly without stabilizing. Add to that the difficulty of manually focusing on and tracking a subject hundreds of feet away.

    For a few hundred dollars you can probably find a 300/4 or 300/4.5, but using the lens effectively will still be quite challenging. You already have the 100-300, correct?

    Yes i have the pana100-300, but i dont like the bokeh that much when the subject is far away.
    So if i could get something that goes down to 2.8, or atleas 3something would be great.
    I have a mono and one tripod that i use when needed.

    Physics. The longer the lens, the bigger the lens elements have to be to make it fast.* The bigger the glass, the heavier the lens becomes. Heavy glass requires big, heavy components to hold it all together. The demand for lenses like this is pretty low, which means the cost of designing and making them is amortized over fewer lenses. All those things in combination add up to big money.

    *A 200mm f4 requires the aperture to have an effective diameter of 50mm. A 400mm f4 means a 100mm (4 inch!) aperture. A 400mm f2.8 means 142mm. The diameter of the lens elements is proportional. That why there's no such thing as a small, fast, long telephoto. Nor a fast, long, good, inexpensive telephoto.

    Maybe give the Tamron 300/2.8 adaptall a look. Should be around $500-600 and 2kg. There's a 1.4X TC you can add to get to 420/4.

    Yeah the tamron adaptall are about the cheapest you'll find...but even they can still be used....i bought mine for my pentax k5, manual focus but still auto aperture. 500-600 would be the starting point too, upwards of $700-800 with tele converters and proper mounts.

    Partially traded for mine total value $800 included 1.4 and 2x tcs, original and new kinesis $100 case and k mount adapter which also would have run me about $100.

    There is also a tamron adaptall 400mm f4 that will run about the same values, but is more rare.
