re-lubed, but still stiff ... what next ?
Posted By Not a Number
Replies: 12

"Stiffness" on lens movement is mostly a matter of personal preference. It is a function of the lens and the hardness of the grease.

If it is too "stiff" then use a softer grease. Hardness of grease is usually rated with a NLGI (National Lubricating Grease Institute) number from 000 to 6 (softer to harder). No. 2 is the most common.

I prefer using Helimax-XP, a PTFE based synthetic grease made specifically with for lens helecoids with a NLGI of 1. Many people find it too "soft" for their preferences but for me it is perfect.

Edit: It appears Super-Lube has a NLGI of 2. Give Helimax-XP a try. You should be able to find it on eBay or Amazon.

What photo editor are you using now? Just playing with the brightness/contrast curves could bring the image out.

Ten Moments in History That Changed Cameras and Photography

That conflicts with the entry on Pentaprism which makes no mention of the Rectaflex:
Pentaprism - Wikipedia
(photo caption)


Also within the earlier cited SLR Camera entry there are conflicts:
(photo captioin)





QuoteQuote:

The Zeiss Ikon VEB Contax S, manufactured in Dresden, one of the two original pentaprism SLRs for eye-level viewing that went into production in 1949. The Italian Rectaflex offered its first production SLR, the series 1000, the same year.



(in body of History section)





QuoteQuote:

The first commercially produced SLR that employed a roof pentaprism was the Italian Rectaflex A.1000, shown in full working condition on Milan fair April 1948 and produced from September the same year, thus being on the market one year before the east German Zeiss Ikon VEB Contax S, announced on May 20, 1949, produced from September.

Wikipedia is a problematic source at best. One should be wary also when a Wikipedia entry cites another Wikipedia entry.

From what I can find June 1981 was when Minolta started with white lens barrels. I haven't found any dates so far for Canon FD lenses. Probably have to go through ads in old issues of Popular Photography. Canon FD lenses don't seem to be as well documented as Minolra.

I seem to recall that the mirror bumpers on the LX are a bit more complicated to remove and install than most other cameras. Jon Goodman includes detailed and illustrated instructions with his kits.

If you're shooting in the studio you can always use the AC adapter to power your camera. No need to change batteries that way.

How are the lenses laid out on the 4 lens camera? If they are in one row than it is probably a Nishika 8000 or similar 3D camera. These are used to make the "lenticular" 3D prints - like the post cards or badges you see with a plastic prisms over the print. The four images are cut into slices and interlaced on the print. The prisms will only show one or two sets of the strips which change with your angle of view.

Has anyone come up with a plausible speculation as to the asymmetrical border under the glass of the rear screen on the left hand side? The only time in the past that the screens have asymmetrical borders is on the bottom of the screen and usually to have "PENTAX" or hociR branded there.

It seems to me that Ricoh's strategy has been to have separate events for the 100 Years of Pentax. If Ricoh has had a presence at any of the shows this year either Pentax is not presented at all or plays an insignificant role. Look at the recent Adobe event in Los Angeles and show in Germany as reported on in other threads.

Case in point:
https://www.pentaxforums.com/forums/16-pentax-news-rumors/397128-pentax-even...rshire-uk.html

And as I recall @Mistral75 mentioned that a Ricoh rep said they were not getting enough return on shows to make it worth while going to them.

SMC 28mm Aperture ring misalignment!??

Excellent! I was thinking along those lines because the meter/foot scale is glued on and often the glue dries out with age and slips off alignment. Or won't turn with the barrel.

Depending on the lens and adapter the indicator mark will align to the 12 o'clock position. I have two lenses that will line up on top with one of my 3 adapters. The same lenses will not line up to 12 o'clock with the other adapters, bellows or extension tubes.

I dount it was like rhat out of the box, Most likely it was serviced to correct sticky aperture blades and not correctly re-assembled.

You should be able to find a disassembly guide to this or similar Takumar lens in the database or on youtube:

Pentax Lens Disassembly Database - PentaxForums.com

Provided you have the tools, skills and experience a DIY adjustment should not be that difficult unless something is broken in the lens. With this vintage lens you should not need JIS cross drivers.

The apparent "notch" has been explained by Albert Siegel as an illusion due to a trick of the lighting and the 2D nature of photographs:



You can see this in the second photo from Albert's post (click on the red quote link button to see the original post):

Imagine that the contour of the rear of the camera curves up/out from the flat plane with the LCD to a raised plane with 4-way controller much as the tip of snow ski curves upward. Then cut out a portion of the curve so a flat rectangular plate attached to the flat part of the ski extends slightly into the tip.

I took Albert's photo and added lines to show where the curve in the contour begins and ends (see 2nd photo above). If you look closely at the original photo the "top" of the curve appears as a faint line. And you can also see a reflection of the contour in the LCD screen lower right (yellow arrow).




Again Siegel mentions that this may not be the final form of the camera. The translation of plaque accompanying the prototype states the form/appearance can change. From what I can make out from the translation of Kimio Tanaka's recent blog that if this is the final form the screen does not move but leaves open the possibility that the production model can be different.

Wait and see. I'm speculating that the new body will be so impressive that even if it lacks of a moveable screen this will not be a deal breaker.

As I recall the only "official" line thus far is that it is slated for 2020 release. No mention of quarter or season that I know of from what's been posted. If there is blog or post from someone attending one of the events with the prototype was present and one of the reps giving a narrower release time frame (i.e. other than just 2020) I wish they would provide a link.

To clarify I'm asking about a link to the cover on the US Ricoh site where it is claimed to have been offered and promptly sold out. I have yet to see it listed on the US or Canada weibsites. Given the glacial slowness of updates on the US site such a listing would still be there weeks after having been sold out.

And I would expect if a US PF member had obtained one they would have posted about it.
