Many 3rd party manufacturers used to make mirror lenses from 250mm, on up, in "T" mount, "T" mount allowed you to adapt the lens to any brand camera (even vintage mounts). I appreciated that versatility.

@MaybeAnnatar 13 дней назад

Definitely not a lens that would necessarily fit into my kit, but I think it provides a really interesting and unique look.

@JakeSloan 13 дней назад

I just picked up a 250mm Minolta Rokkor reflex lens to fly on the Inspire 3 and use on my sony. It's fascinating to shoot with, the bokeh is interesting but the reach in such a small package is amazing.

@markwiemels 13 дней назад

Interesting that you mention that lens. I’m testing a yet to be released 250mm reflex lens that was inspired by the fact that the vintage Minolta is so sought after. The mirror lens thing is pretty cool.

@TheLDunn1 13 дней назад

I have the Rokkor 250mm too, had it a while. Lovely little lens, and I like the images it has given me, but, it’s not so good if you try to use it for stitched panos, that’s it’s weakness.

@Daniel_Borisov 13 дней назад

Wow Mark, stunning street photos with this little gem! Depending on camera, foreground and background distances, the bokeh makes the photos look a little like paintings rather than photos. From all unique look lenses you've shown us, this one has to be my favourite. And 100% the optical flaws here contribute to the look of the images. Congratulations on the manufacturer for their first lens!

@sleibson 7 дней назад

When mirror lenses first came out in the 1960s and 1970s, the prominent donut bokeh was considered undesirable but these lenses were much cheaper than the refractive competitors. My, how things have changed. At $600 and up, the Kase lenses are very pricey but you find the bokeh pleasing. Tastes change over the decades, I guess. I have a Vivitar Series 1 600mm solid cat lens from the 1970s, bought used in the UK nearly 20 years ago. Manual focus, which makes it hard to focus because it's a huge, heavy beast. Maybe 200mm is the right focal length for a mirror, but it's way out of my price range. You got yours for the price of a review. At that price, I'd be happy to have it.

@peterreber7671 9 дней назад

This looks good. I had a Minolta Rokkor 250mm and 500mm (so heavy) lens from around 1975. When I tried them on my M50m2 they were so shockingly bad, unsharp, low contrast, that I gave them away to a photo equipment collector within days.

@sgcdialler 13 дней назад

Love to see some love for mirror lenses! I shoot deep-sky astro and very long telephoto with a vintage Tamron 500mm f/8 55BB with good results. A lot of mirror lenses were produced with poor quality, which is what gives them their bad reputation, but there are a couple models out there that were produced very well and give great results.

@Original_Old_Farmer 13 дней назад

Good Video! Here is a topic you can discuss, and it would be a good one to keep in reserve if you can't do a video. What is the difference between medium and full frame. It doesn't seem to be the number of pixels. As an example Fuji has a 100 hundred megapixel camera that is medium frame. I have seen full frame as low as 26 megapixels. So what denotes medium and full frame?

@williamjones1590 9 дней назад

Hi Mark, another great review. How do you think this lens would go at outdoor photography of insects? We are a Canon family currently with a 750D and a M50.

@HumbertoAbed 13 дней назад

I had a mirror lens back in the 90s. I got it with my first SRL camera, a Minolata Maxum something. I was surprised of the focal length and the size of the lens. I don't remember the exact focal lenght but I went to a Dolphins game, was sited all the way up in the grades and still got medium shots of the players. The people who went with me to the game couldn't believe it. I sold the lens together with the camera some years after and never got another mirror lens. Don't know why. probably because you don't hear bout them much. This one looks interesting. Love the bokeh and 200mm is a great focal lenght. I may save for a while and give it a try. Thanks for sharing

@nyax4361 12 дней назад

Kase made a "mirror effect" filter before for 24-105mm standard zooms, basically blocking the center portion of light to replica the circular bokeh. It was pretty cool, but results differed from lens to lens. I'm a little bit surprised that they would go this far to make a dedicated mirror lens though.

@bueb8674 10 дней назад

Mirror lenses tend to be very sensitive to stray light, part of the reason for the low contrast. That hood is probably too small to help much. I've got a Tokina 400mm szx and the hood is the same length as the lens.

@ChopsticksDIYGarden 12 дней назад

@petercharles6652 13 дней назад

Interesting images from this lens. However, I find the $750 price for the Canon version too steep for a lens that might only be used occasionally, especially since it is missing electronics and aperture. Further, never understood why an aperture blade option cannot be added near the rear lens mount, which would certainly make the lens way more versatile?

@MikeC2K10 13 дней назад

Another drawback to this sort of lens design is that the central obstruction significantly deteriorates contrast. At f/5.6 the obstruction is very large relative to the entire aperture. At f/8 or f/11 - which is more typical for this design - it's much better, but still quite inferior to a refractive lens. This isn't correctible in firmware or post. The obstruction removes information from the image.

@TheLDunn1 13 дней назад

Lots of 500 & 600mm cat mirror lenses around, not so many at the 200-250mm range.

@mylucksmiles 13 дней назад

I agree this is not a normal lens, personally the bokeh looks more like a horror movie trip. The size is great plus but I could not think of any reason to use it personally . I would have to get new horror movie commission . The fact there is. New lens maker is far more interesting. But I am into horror and fantasy images I will hold on to see if the lens drops in price and more interesting I would love to see more video than stills cheeers

@terrygoyan3022 12 дней назад

Nothing like it? The only thing odd about this lens is the relatively short focal length for a mirror lens. Otherwise, most start around 500 mm and I've found the donut specular highlights hideous! Used Nikon mirror lenses came in 500mm, 1,000mm and a behemoth 2,000mm focal length. The prices on them are extremely cheap because of the limitations they have.

@markwiemels 12 дней назад

Their idea was to make a "modern" mirror lens with significantly better optical performance than the vintage options. I think they have done that, but not everyone is going to like the character.

I’m sure retailers would LOVE that model.
