They have 500mm and 600mm DA* lenses?



While adapters aren't plentiful, there are a few around such as the Leitax.

Leica & Pentax & Nikon | Leitax
I was able to see this when I googled adapters from our site.
There are quite nice but once people get a wind of this, all those not so epxpensive lenses will shoot up in price again since they would know that the Pentax people are using them again..or has a use for them again.
This is exactly what happened to the cheap old prime lenses before.
Now, the good old primes are just ridiculously priced too!

The Tokina 500mm f8 was also sold as a Sears brand lens.

This is good to know and another brand to look for, I guess.

I have the 500 mm f/8 Opteka, one of the brandings of the modern mirrors being sold on the internet. I picked it up second hand on Ebay for $49 from a seller who didn't like it. A few of my first attempts were not good. It takes practice and a very steady hand to focus one. While the lens is very light, being a 500mm makes it very difficult to hand hold. On a monopod and using trap focus, I got some surprisingly good shots of my daughters crew team. I bought it this fall and the weather has been dismal and I still haven't been able to use it much in the conditions where it will perform best, which is in bright sunlight. The few sunny day test shots I took with it looked quite good.
..as Marc had said, maybe it doesn't actually matter which brand to get, the more important thing is the technique!

I'm liking the Vivitar Series one offering now 'coz it seems small compared to the other mirror lenses but the reviews I have read are so-so.

BTW, I'm not saying the lens isn't so-so - it's capable of some pretty bad pictures too. And don't ask to see 100% crops of even the better shots I've taken with it, like the above - they won't be particularly impressive. But the way I figure it, long mirror lenses are about not *needing* to resort to extreme crops to get the framing you want (I shot the arch from around half a mile away).

Although I've been quite impressed with my Tamron 55BB at 100%:

If I managed to get a 100% crop like this from my 55BB I would be feeling quite pleased with myself. The aparent image degredation / graininess is due to the high gain at ISO1600 which makes the image very noisy at 100% crop. After putting the picture through a median filter averaging over 9 pixels to supress the noise it looks completely different and still remarkably sharp for a 100% crop from a mirror lens:

Yes Marc, I have already visited that site and am quite impressed by some of the photos.
Are all the Vivitar Series 1 mirror lens all the same?
I have seen some being offered right about in the below $100 and one around $140.
The one being offered at a higher price looks like a new model and I'm not sure 'coz I haven't had any experiences with these lenses.
Some of the shots you took where great.
I'm not really fond of the f6.3 versions as they seem so huge!

I'm not very fond of cropping and don't usually crop.
I always want to nail my framing.

Googling and looking at all the available options, I'm still overwhelmed!
I see some say that it has or is capaple of macro focus but I see that they all have the same/almost the same minimum focusing distance..so I don't see how this is.
I don't see the Vivitar series 1 saying it is capable of macro focus.
I see some that say they are for a different mount but am not sure if they are actually t-mounts that has a changeable adapter or if they have a fixed mount for that certain mount only.
Boy am I now more confused than I was before!
I don't even know what to get now or how to look at the specs!
Some have lesser elements in groups (lens) and some have 6 elements in 7 groups..I think!
I'm getting more and more confused!
Argghhh...

If it were me, i'd buy in this order: Tamron 55BB, Tamron 55B, Tokina, Sigma 600. These offer the best image quality for your $

Depends on whether someone wants to call the magnification you get at that distance "macro" or not. As I recall, the actual magnification of the Vivitar at closest focus is 1:2.6 - which is *slightly* better than the kit lens at 55mm. But the Vivitar (Samyang), much more so than the Tamron from what I can tell, is *really* bad when focusing close. So while you can get 1:2.6, you probably won't like the results at all.

BTW regarding whether all current Vivitar 500/8's are the same - you'd have to post a link tot he one you think might be different. I'm inclined to doubt there is any difference except the asking price. But there was, apparently, an older pre-Samyang Vivitar 500/8 that was different.

If it's the Samyang lens (whether under the Vivitar or another name), it's definitely T-mount, and the adapter can be changed. In fact, *sot* mirror lenses are T-mounts, I think. The Tamron is its own world, and the Sigma was made in native mounts, but most others (including the current crop of 500/6.3's) are T-mount.

Some specs on most models (size, weight, minimum focus distance, etc):

OK, since we've seen a 100% crop from the Tamron, I might as well show a couple from the Vivitar/Samyang.

Here's a crop from the arch shot above:



And here's a crop from another one of my favorite images from the Vivitar. First, the full (resized) image:



And now the crop:

I just let go of a Sigma 600 posted at ebay which sold only for around $50!
Although it had the Yashica/Contax mount, I have read that it is an easy conversion to a K mount. A mere getting a K-mount from a donor lens and swapping it with the existing Yashica/Contax mount.
..oh well, there will be another time. That lens may not have been for me.
