500mm Aubell Lens, F8, is this worth buying?

Hi,

I came across, as the title says, an Aubell F8, 500mm prime lens.
Its roughly 17 inches long, believe its a screw thread, it can be had with a 2x teleconverter and adapter for Olympus.
Apparently made in Japan.

I just saw a Etsy posting for a Rokinon brand lens, same specs, looks to nearly identical..

I found a review for a 400mm Aubell, which says its minimum focus distance is about 10 ft.

If it takes crappy pics, there is no point buying it, I don't need something collecting dust.

I have a Pentax DA* 300 prime, almost never used... ha ha

Thanks in advance!

Generally speaking (and Im sure there are some exceptions), there are two kinds of 500mm f8 lenses...
1) cheap mirror lenses that use T-mounts and are usually not very good (again, with some exceptions that are much less cheap)
2) cheap skinny regular lenses that use T-mounts and are not really any better (though they will have variable apertures)

If you have a DA 300, you can get a teleconverter and likely do vastly better. In most cases, you can crop in with the DA300 and still do better.

Id be happy to see an exception to my gross generalization

T-mount "long lenses" are more useful for fighting off animal attacks than photography.

i had not previously heard of Aubell, I would guess it's just another reseller nameplate, probably a short lived one judging from the lack of online info. I saw that review by Kowalski of the 400mm, that looks rather like the 9xxx.. soligors which are 1969-71. Pretty much all the 500mm f8's are the long skinny generic ones, which I don't recommend.

You need to get out and start using your DA 300mm!

The DA* 300 is a great serious lens, if you don't use that, why do you want a toy? Yes it will take crappy pics.

Probably not. I tested this idea with my 500mm Kalimar f/8 preset telephoto vs the superb SMC Pentax F* 300mm f/4.5.

I shot the same static subject with both lenses on a 24MP APS-C camera, and then cropped the 300mm image to match the field of view of the 500mm lens. When viewed at the same size, the 500mm image had slightly better sharpness and detail... and a bigger problem was that the cropped 300mm image was simply running out of pixels: it was about 7MP in size. Crop the 500mm image even a little and the matching 300mm image will drop under 5MP and become unusable for many purposes.

Below is a cropped image taken with my 500mm Kalimar. It doesn't match the image quality that you'd get from better lenses like the 150-450mm or the 560mm, but it's not bad. My local newspaper was delighted to run it.

When I've done similar tests Richfam, 500mm f8's vs soligor/tokina 400mm f6.3's, the 400mm crops/resizes were equal or better than the 500mm f8's. But thats a fine result there with the kalimar.
Did you use live view? i've always found visual focus at f8 (as with mirrors) with those lenses iffy too, even with an OVF magnifier.

At f16, you could even put a 2x on the 300mm and have a viable alternative.

Since youre shooting APS-C, the 1.4x is available new and well regarded. 420mm at f6.3 is pretty close to 500mm at f8, and youd get autofocus...

That's interesting. Modern Photography magazine, back in the day, did an in-depth lens review matching a 500mm f/8 preset with a 400mm f/6.3 preset. The review concluded that both were good but not great lenses that worked best when stopped down about two stops. But the 500mm lens had slightly better resolution results. Might just be lens variation, or, if your 400mm f/6.3's had automatic apertures they might simply be a newer, better optical design than the older preset lenses.

I find Live View to be unusable outdoors in bright light, so no, I was focusing strictly with the OVF. I spent over 20 years photographing sports with manual focus cameras back in the film era, so with all of that experience I don't find using manual focus with the OVF on DSLRs to be all that difficult. Although I will say that focusing on a fast moving subject with a 500mm preset stopped down to f/16 is a bit of a challenge!

I have a Tamron 55BB 500mm f/8, one of the better 500mm mirror lenses. While in theory the image quality is acceptable under the most ideal conditions, it is exceptionally hard to focus being an f/8 lens. It can take good shots of flowers and large, slow moving mammals. It is horrendous for birds. Even with good technique, the keeper rate is like 1/30. The only reason why I've kept the lens is because I like the quirky bokeh and it is passable for video in a tight spot....though I am not sure I am going to keep it much longer.

Although 500mm is nice, you really have to know what you are gong to use it for. It is nothing like carrying around a modern supertelephoto 500mm (which I do on a regular basis), which can be used in almost any situation without a second thought.
