Vivitar lens

That's pretty bad If the tanning salon doesn't
work strip it down and clean it with Ponds Cold Creme
leave it on for about an hour.

'

Wont that make the lens Soft?

Viv is back from her holiday on a sunbed and I can't see the slightest improvement.

So I think the next tack is to get her stripped and rubbed over with cold cream

I'll keep you posted on progress

I am surprised at how easy it was to get at the front lens (the whole front section unscrews then a tiny grub screw releases another ring)

Any way I used Algi's cold cream remedy and I now have a crystal clear lens to play with, see :-


.

The dust is on the outside of the lens (I know Ishould have cleaned that off prior to snapping the lens)

That looks great It's surprising how easy some lens
front elements are to work on. I don't think you'll have
any more problems with that one.

Bit of a dull day in the garden but I think the lens is working OK (at least to my satisfaction)




K10D in manual mode ISO 200; f2.0 - green button came up with 1/1500.
Original was a tad dark so lightened just a bit in PS7

Nothing wrong with that...

Be even better in about a month - ie plus crumble

As Spike Milligan once said " It's only the hair on a
Gooseberry that stops it from being a Grape!"

That is major modification from where I'm sat

I've got a 70-210mm Macro lens and have the same issue, I did post about it some years ago.

Would my local camera shop undertake a modification? Alternatively, if anyone wants the lens, I'll discuss a swap/part ex etc.

I suppose it could be classed as major surgery but quite easy if taken steadily.

I first turned a wooden mandrel onto which the loose ring would slide firmly.

A stepped shoulder stopped the ring at the required distance.

I then cut around with a fine hacksaw blade (the end of the wood preventing too much straying from the line)

Finally finished with a fine flat needle file (again using the end of the mandrell as a guide)

A quick bit of fettling on all cut edges to remove burrs etc then washed off any debris with plain water.


Probably a bit long winded to some but the result is in my 2nd pic.

I then dabbed some black acrylic paint over the cut edge (pic #2 taken before this stage)

I've done something different - found a 52mm reversing ring in the box, so I've reverse mounted the 70-210mm onto the K5.

When I've got some results, I'll post them
