Dust particles inside lens
I'm pretty sure you will always get some dust in a large zoom lens , by it's very nature it can't be 100% sealed as it has to move air through itself when moving back and forward. Except that it is supposed to be dust and weather resistant. Having said that I normally wipe the extended lens barrel i...

Dust particles inside lens
I used to watch a professional photographer go to town with a Rocket blower, taking an eternity blowing inside the mirror box at 4 x 90 degrees and then 4 x 45 degrees and then blasting the body cap that was quickly applied. He then did the same with the lens he had just removed, as well as its caps...

Tamron Twin Tele - the lens porn - 6 pix
Dunno if you can make 'porn' out of these since I used natural light from one direction and tungsten from the other. Either way, it's provided a nice pink cast to everything! I have two of these so I leave one as a 135mm and the other as a 225mm. The photos show one or both of them. 1 This i...

Infinity focus gone on my early version Super -Takumar 35mm f2
years ago I got an early version Super Takumar 35mm f2 with the huge front element off an Old Gent with my SV. It WAS perfect -- now giving it an 'outing ' I find it will not focus to 'Infinity' -- all tests are out of focus! Also, something indoors at about 9 feet away is over 30 feet on the focu...

Infinity focus gone on my early version Super -Takumar 35mm f2
it may be worth using another PK/M42 adaptor just in case. The original Pentax version is preferable, at least in my experience.

Infinity focus gone on my early version Super -Takumar 35mm f2
Is there anything rattling in the lens ? It may be a loose element.

Infinity focus gone on my early version Super -Takumar 35mm f2
it may be worth using another PK/M42 adaptor just in case. The original Pentax version is preferable, at least in my experience. I'd normally agree but it doesn't explain it being OOF at infinity on the S3. This might be exacerbated when adapted, for sure. I'm wondering what aspect holds the infin...

Infinity focus gone on my early version Super -Takumar 35mm f2
There are companies that specialise in old lenses, so it may well be that such a lovely lens deserves letting them have a look? I have had some tricky jobs done by Newton Ellis in Liverpool - www.newtonellis.com

Infinity focus gone on my early version Super -Takumar 35mm f2
I wondered if there was something inside but could not hear anything - I have sent an e-mail to Harrow Technical -- I know they are no longer in Pentax House though. That K-M42 Adapter is the real PENTAX one

Infinity focus gone on my early version Super -Takumar 35mm f2
Just had a Reply from Robin at Harrow Technical -- he wants £90 quids to do the 35mm f2 Super Takumar NOT the £47 as in his web--site and I mentioned my SMC Takumar 200mm f4 needs a de-grease as it has all gone solid the grease but he thought it was a 'ZOOM' and says it needs an estimate - surely ...

is there anything more complicated about the early 35/2?

Infinity focus gone on my early version Super -Takumar 35mm f2
It shouldn't be difficult at all to sort out infinity focus on the Tak. If it's like other Tak lenses, you'll need to unscrew the front ring to gain access to the infinity adjustment screws. Loosening them allows the focus ring to move freely without moving the helicoid. A bit of trial and error ...

Infinity focus gone on my early version Super -Takumar 35mm f2
I sent it to Alan Marlow -- he quoted £40 for setting the Infinity focus and £60 to strip down and clean and re-grease the SMC Takumar 200mm f4 with correct grease. The SMC Takumar 200mm f4 cost £61 NEW in 1972 from David S.H. Leung camera dealer of Goodmayes ! Repairs are a big chunk out of my r...

Updated Limited lenses
From what I can tell the only differences (apart from possibly price) are a change to HD coatings and rounded aperture blades. I would have thought that at the very least they'd add quick-shift if not WR and an in-lens focus motor, to bring these classics up to modern standards.

Updated Limited lenses
The danger with going too far to "modernise" these three gems, is that the individual quality they possess could be lost. HD coatings by all means, but anything more must mean a complete re-design. I won't be in a hurry to replace my old versions. I am well used to knowing when to use say the 31m...

Recommendations Needed.
Geoff, sounds like a great idea to me! I'm oftentimes flicking through usedlens.co.uk for cheap stuff. Chuck something like 'pk' into the search, click the 'lenses' option at the bottom and sort by price and you should be off to a good start (though there are a LOT of zooms, not sure how that would ...
