Nice tantrum.

If Ricoh's business analysts come to the conclusion that that a wider prime would be profitable to manufacture and market given their installed and foreseeable future user base, then they will do so. It has nothing to do with "apologists holding the brand back." I'm sure there is a subset of users that would like an enormous 900mm telephoto prime in order to shoot birdies too, but if only a half dozen people buy them at $50k a piece, it still won't even come close to covering development and manufacturing costs.

As you know, the water in the Potomac ain't exactly crystal clear, either. Heck, the treated Potomac water coming out of my tap has been brown since August due to dissolved organics and manganese.

@RockvilleBob: Hawk Mountain in Hamburg, PA experiences an eagle peak this time of year, but again, there won't be the same kind of density as at Conowingo. However, the presence of other Raptors might still make it a worthwhile weekend outing. It's about a 2.5 hour drive from the DC metro, and there is nice hiking in the preserve, as well as excellent free hiking on the Appalachian trail at the Pinnacle and the Pulpit if you are into that sort of thing. There are also some bald eagles at the Middle Creek Wildlife Management Area near Lancaster, PA, but the big story there is always the giant waterfowl migration (up to 100k Tundra Swans) in February. The drive time there is similar to Hawk Mountain.

in VA, there are Caledon State Park (2+ hrs), and Mason Neck Wildlife Refuge (~1 hr), each of which have decent nesting populations. Both are on the brown brown Potomac but have better backdrops of vegetation during green times of year.

I'm not sure if any of the Cosina-made Vivitars are still in production, but they were (are?) mostly cheapy AF zooms, some of which were also sold under some of the same rebrands under which more recent MF Samyangs shown up.

I don't have experience with these models, but I can describe how this would generally be done in a FPS camera of this vintage. Typically, it would entail removing the bottom plate and front leatherettes, followed by the mount and mirror box, then taking the rollers and shutter out. In cameras this age, the leading edges of the curtains are usually attached to the rollers with contact adhesive, which would be carefully removed, while the opposite sides (the streamers) are attached to little metal frames that simply unhook. Once detached, the original shutters can be used as a template to cut new ones, reusing the existing frame at the streamer end.

The rollers work essentially the same way that a window roller shade does, so they have to be glued on at the same location on the roller and pretensioned while being inserted back into the camera. Once they are in, there are fine adjustment tensioners that can be adjusted to make sure both curtains are moving evenly and at the correct speed. Once everything is tuned up, the front of the camera is then reassembled.

Tim's right. Literally everything you describe is 100% normal behavior.

It's also not a preset lens, for that matter.

Is this dust or fungus?

Fungus cannot jump form lens to lens. This is an idiotic myth that is constantly perpetuated on online camera forums and needs to die now. Every surface of every element of every lens you own already has fungal spores on it. So do your camera's mirror and viewfinder surfaces. Spores are omnipresent in the environment, and if air can get into the lens, then so can the spores.

The ONLY thing that causes to grow on gear is storage in an area conducive to fungal growth. Keep your lenses out of damp, warm, and dark areas and they won't get fungus, even if stored next to a badly infected lens.

This lens is perfectly safe to use, and honestly, that amount of fungus/particles at that location in the lens will have zero effect on your images. So shoot away!

About 99% of the thousands of Vivitar lenses in Pentax mounts are not Samyangs. Since Vivitar (Ponder and Best) ceased to exist, the brand has been attached at times to some of the various multibranded Samyangs and Cosinas, but it's only a handful.

If you don't want to deal with the same issue a few years down the line, adhesive-backed felt is a common permament replacement for the mirror bumper. Black wool yarn can also be used in the door seals.

Was it stored in a hard sided case? As the velveteen inside them degrades, it can produce little particles like this that can and do stick to glass surfaces due to electrostatic charge. They are easily wiped off exterior surfaces, but they'll migrate inside the lens and stick to the exposed surfaces adjacent the aperture.

What's the lens model? It may be a simple matter of unscrewing the front or rear group and giving a few quick puffs with a rocket blower.

"Reverse T" mount adapter, so 42mm but with a different thread pitch than m42. The application for this would be to mount a lens with a proprietary mount onto a T mount macro bellows (which Spiratone sold).

You can get to m42 by using this in conjunction with a T to m42 ring, but it would only be usable for macro photography.

The interiors and exteriors of these cases are synthetic, so acetone would be a bad idea. Alcohol might work, though.

Have a D board drilled with a Copal standard hole and mount a lens in a leaf shutter with flash prongs/port. Set the camera to timed exposure (T) , open the focal plane shutter, and use the leaf shutter for setting shutter speeds.

I don't have any direct experience with this lens, but based on its focal length, you are likely going to require a lot (100+mm) of extension rings to achieve 1:1 macro magnification.

Malfunction when shooting with 100mm macro WR?

Sounds like you might have lost a tooth in the focusing ring gear. The binding was probably caused by the broken tooth sticking, and once it finally came loose and fell out, you were left with a small gap in the gear causing the clicking.

If it's under warranty and you can live without it during the processing time, I'd recommend returning it for repair/replacement, since the loose tooth might be floating around inside and could get caught back up in the gearing again, causing more damage.

On a forum devoted to a brand that never produced a LF camera...

But hey, LF view cams are so superior in every way that there's no point in comparing any 35mm in any way to them, right? Especially not in terms of aesthetic appeal BECAUSE ALL THAT MATTERS IS THE NUMBER OF SILVER HALIDE GRAINS PER IMAGE, AND DON'T YOU FORGET IT!!!!!!!!!

Anyway, bringing this thread back around, might I suggest a slogan for this company:
"Reflex: at the very least, a nice looking camera!"

You're missing the point. We were talking about aesthetics of the equipment, not the size of the image it takes. Aside from advances in shutters, LF cameras have gone through relatively little in terms of design improvements for over a century, and there are loads of ways that they could be improved to function better and look prettier. It simply hasn't been done since the advent of practical enlargement of MF and even "good enough" 35mm film killed LF use for all but a small subset of art and architectural photographers.
Heck, when was the last time you saw a photojournalist carrying a Graflex, which even a the end of its run midcentury was much less of a Rube Goldberg contraption than a standard view camera like the Ebony?

Your RV comparison is completely backwards, too, since your entire argument boils down to size of the negatives LF can make. It's more like comparing living in an empty circus tent to living in a modest classic polished aluminum Airstream. Yes, if your only concern is size, the tent beats the trailer by miles. But even if the tent is made from the finest silk from China and brocaded with pure gold thread, the Airstream costs less, looks better, is climate controlled, has a bathroom and stove, is much more easily moved, and has you sleeping in a bed rather than on the ground among the elephant dung. Sure, you won't be able to set up your trapeze in it, but the vast majority of people looking for non-permanent housing aren't aerialists.

Not only that, based on the photos and description, I count at least 4 separate damages to the lens (front element, removed mount, damaged aperture mechanism, front and rear half of the lens coming apart) that would render it completely unusable, not to mention evidence of multiple extremely heavy blows to the hood, foot, and body of such strength that even one would likely lead to an unusably broken lens.

The condition of this lens screams single catastrophic incident rather than habitual rough usage.

Are you referring to the Ebony view cams? I suppose they are attractive in the way that a 1902 State Landau is compared to less tricked-out horse-drawn carriages, fine examples of craftsmanship, but ultimately rickety and unwieldy 19th century technology.

The great postwar mechanical SLRs are more like a 58 Corvette or a 61 Ferrari California, voluptuous and functional distillations of the finest jet age mechanical and industrial design.

It was the 1.22. When I was looking to get another, I got a deal on the OME53, so that's what I went with. I was using the Tenpa on APS-C, so I can't attest to how it would fare on a K-1, but on the K-3, it helped a lot.
