Arrived safely yesterday, as described.
A quick trial last night is promising, nice to have a quality TC with AF at last.

Thanks Mark!
BTW which system are you switching too & why?

Excellent set!
I life the movement shown in the blades (don't think I've managed to get the body sharp & movement in the blades in any of my attempts at sea kings).
No 3 is probably my favourite.

You have to be rather careful with 'naphtha' too. It's a rather generic term used for widely ranging hydrocarbon mixtures. Some 'solvent naphthas' contain nearly 100% aromatic hydrocarbons that can be quite effective at attacking plastic. (I've had fingerprints etched into many biros by traces of similar materials on my hands).
Lighter fluid is usually fairly low in aromatics (they burn with smoky flames) and usually has weaker solvency than petrol.

Mike next time at your refinery (end of the month) I will look out for someone without a beard.
If your visiting Harwich give me a PM & I'll try to have the bigmos available to play with. But I'll be out on the 22nd & 25th as I'm working the weekend at the Croft BTCC race.

Hi Mike

Sorry another MAK (Daughter) and she doesn't have a beard.The 150-500 is heavy enough especially trekking to sites.

With your pseudonym I hope you are not tied up with the bad goings on at Coryton.

thanks

Cedric
I thought perhaps there must be another MAK (though my beard went years ago). I'm sure your daughter will make better use of it than I would, the K10 doesn't offer any advantages over my K7 that I'm aware off.

Agreed the Bigmos is heavy, having only used mine handheld so far, it's rapidly become noticeable waiting for a gold finch to take wing - naturally he kept me waiting for over 5 minutes keeping to a single (much photographed) pose, then left whilst I was taking a rest - but the Bigma is heavier still...

No not involved at Croyton (thank heavens!) I'm at the other end of the county in a refinery too small to show on any of the news reports of dwindling refineries.

I've recently got the 150-500 which has been performing rather well on it's initial trials. If your not likely to use the shorter focal lengths, I think this would be the better option for you. It's lighter & Cheaper, and physics suggests the optics should be easier to produce in a well corrected form. (Longer focal ranges are more complicated to correct)
IQ from the images I've seen in galleries seems to be good for both.

BTW as my initials are MAK I'd like to know where the K10 has got to. I didn't know I'd inherited anything.

There are elements of the Trift Bore, Machine Gunner, & Artisan that I think apply to me even though the last two seem almost oposites.

Of the three Thrift Bore is probably closest, but I certainly don't go on about 'full frame' The largest camera I have is nominally 1/4 plate and bigger is just to clumbersome!

It's odd that the larger the negative the smaller the numbers used to descirbe it;
My Large format is 4*5 (inches), my medium format is 6*9 (cm) using 120 film & normal 35mm is 24*36 using 135 film.
