    If it had AF, I might think about it. At that price, I don't really see the point of getting this over something like the 100-300.

    Love this piece of specs... finally a mirror lens taking advantage (I bet) of the smaller sensor.

    Would be nice for telephoto for travel. I don't mean safary, I mean static shots like these

    I bought 14-150 for it, but, sometimes, wish I had more reach, and Pentax 300/6.3 that I have is not great for long distance travel.

    It is less than half the size. I'm also hoping it'll perform better than the panny does at 300mm. I'm hoping it's going to be pretty sharp and that vignetting will be alost nil. I know the bokeh shape isn't something that you can do much about, but it'll be interesting to see the character of it nonetheless.

    TBH I don't see it selling for that price in the real world, at least not for long. Third party lenses usually come down dramatically in price, and do fairly badly on the used market.

    Can someone make sense of this translation?

    "This is a manual focus lens. Why did not adopt the auto-focus, depending on the following two points.

    ● ∞ angle is greater focus to the minimum shooting distance of 0.8m from.
    ● focusing angle of view is very severe, and request 4 ° 8 '(equivalent 600mm equivalent version 35mm) 300mm.

    Because of this I thought, and allows the Focus to ensure that more of the operation manual."

    My best bet: long focus throw because lens can focus between 0.8mm and infinity, yet need very precise focus because lens such a narrow FOV. What this has to do with the inability to AF is completely beyond me.

    They are saying,it'll wouldn't be worthwhile to have autofocus, it'll be slow and cumbersome.

    I don't think any AF mirror lenses exist.

    This. I bought the 75-300 specifically to have a small 300mm lens. This one looks to be even smaller, and if I hadn't already bought the Olympus I'd be considering it. If this ends up being priced similarly to the Samyang 7.5, it would still be worth considering...

    Personally, I wouldn't be interested at that price. Would love to have something longer than my 40-150mm but if it's manual focus and a mirror it better be cheap.

    LOL, you're probably right.

    Thing is, as I read it, those some objections would hold for ANY 300mm lens. And obviously those can be made to AF.

    (Actually wouldn't the 'slow' part have to at least in part with the mass being moved around? I'd think that would be less with a mirror lens than with a conventional refractor.)

    The size definitely appears to be the main attractive attribute of this lens. It's less than half the length of the Olympus m.ZD 75-300 and the Panasonic 100-300.

    One disadvantage beyond the lack of AF is that the aperture is fixed at f/6.3. That's slow enough that you probably wouldn't want to stop down to begin with, but in any case, you can't.

    Also, there's the famous 'donut bokeh'. Photozone has a nice summary of mirror lens attributes.
