Unassuming, PK mount 2 X TC, Rokinon branded, in good condition (mechanical/optical) seeks new owner willing to explore/exploit its potential for use either for the purpose intended, or, once the optical elements have been removed, as a 25mm extension tube. Comes complete with lens and body caps but no case or documentation.

Postage £2.00 in the U.K. or £2.25 in the rest of the E.U.

Why does it need cleaning? Unlike the sensor, which is protected by an anti-alias filter, the silvered surface of the mirror has no protection and cleaning it is a much scarier proposition. So much so that it is probably best to leave well alone or consider having it done professionally. IMHO, even delicate swabbing with a cotton bud soaked in isopropanol is likey to do lasting damage.

Best wishes,

Jon

I presume you mean this, Trixie: link

Providing it is the K-mount version, it will work with your K-x (Av mode) focussing will be entirely manual: not necessarily a bad thing but something you need to be aware of. If the crop factor of the K-x sensor is taken into account (approximately 1.5x), it will give a field of view roughly equivalent to that of a 50-105mm zoom lens.

It is an old and heavy lens, potentially making it a poor match, in terms of handling, for the K-x, and without careful use is unlikely to produce images that will prove less than satisfactory for anything other than small prints. Neither is it a 'macro lens' in anything other than name: a more accurate description being 'close focus' (around 1:4 at the most).

The questions that beg to be answered are, therefore, what would be your main use(s) for this lens and how cheap is "quite cheap"? If the answer to the first is macro photography, it is definitely not for you. In terms of value, I would estimate somewhere in the region of £20.00 for an example in 'mint', or very nearly so, condition, but other forum members with experience of having used this lens would be able to give a better estimate of its potential worth.

Hope that helps,

Best wishes,

Jon

May I be one of the last to offer my most sincere and heartfelt congratulations on the long overdue, public acknowledgement of your exceptional skills and contribution to the field of photography

Inestimably yours,

Barf - pass the sick bucket somebody, please

Enough of the teasing, already: seriosuly well done Jim

The only limitation that the current version of GIMP has, at least for Windows, is that it is exclusively an 8-bit editor, which may or may not be of importance to you.

Another programme I have used and am more than happy to recommend is Photofiltré Studio, which is a powerful, well supported image editor; albeit with a somewhat idiosyncratic interface that takes a little time and effort to become fully familiar with. A fully functional, 30-day trial is available to download, after which it costs a measly, IMO, €29 for a license. Check it out here link.

I looked into the supposed benefits of using these very same batteries but, after a bit of research on the web, came to the conclusion that, for me giving the number of rechargeable MN1500/AAs I use, the switch would not be economically viable.

I also wondered about the 'real world' benefits of 1.5 vs 1.2V. What I read, however, seemed to suggest that with most modern battery powered electronic equipment the ability to maintain a high current output is of far more significance.

In the end, and having wasted a not inconsiderable sum on cheap and not so cheap batteries in the past, I decided to standardise on the use of Sanyo Eneloops. An improved version of the original type has been introduced recently, as has an higher current drain variant link.

The other factor that is often overlooked is the quality of the charger, which is often the determining factor when considering the reliability and lifespan of the rechargeables used. After, conducting the usual OCD-style research, I went ahead an purchased a model from Powerex/Maha link, although I know from experience at work that the top models from Ansmann are also very good e.g. link, but difficult to find discounted to any significant extent (I was fortunate in that the Powerex/Maha was on 'special' at Maplins when I bought it).

To summarise, I have found the Eneloop/Powerex combination to be of high quality, reliable and suitable for use with all of the electronic equipment, including photographic flash, powered by MN1500/AA batteries in my possession. I cannot comment, however, on their suitability for use in DSLRs such as the KX or KR.

Hope you find at least some of this informative and/or helpful, Peter.

Best wishes,

Jon

[quote:3496ace15f="Crossed-up"]I stopped in Bruges en route to the Nurburgring. Having some time to kill I thought I'd try my hand at a bit of street photography. It's out of my comfort zone but I was happy with these two.[/quote

Deservedly so, IMO

Une image vraiment remarquable

Tres bien fait et félicitations a vous, la truie, et le petit garcon - excusez-moi, jeune homme

Amicalement,

What an unnerving prospect

Although your suggestion emerged from my 'Logical Basis Detector' with a triple-A rating, my emotional/irrational overide circuits entered an infinite loop at the thought of using any cloth not specifically marked and marketed as safe for use with 'precious glass' to caress the delicate, irridescent surfaces of my true loves. Fortunately, my wife was around to administer a non-soft reboot!

Must dash as I'm overdue for my weeky dose of self-administered therapy using my trusty JML As Seen On (Subscription) TV Anal Retentivity Suppression Electrode.

Yours painfully,

Jon

If you were sufficiently forward thinking to snap these up when 3M were running down stock earlier this year , but now realise that you purchased more than enough for your needs , please get in touch as I should like to purchase between 5 and 10 for my own use.

Thanks for looking,

Jon
