Jessop Macro kit, Sony DSLR A200 and Sony DT 50mm F/1.8mm SAM prime lens

Something New from the Car Boot Sale

Jessop macro kit – 2 x tele-converter and three extension tubes with Sony DSLR mount. Taken with the Sony DSLR-A200 and Sony DT 50mm f/1.8 SAM lens.

Well, not as ancient as my usual purchases at the car boot sale.  I bought something for one of my digital cameras at yesterday’s sale!  What are the chances of bumping into something with a modern Sony DSLR mount at a local car boot sale?  Pretty slim I’d say.  I don’t see much modern gear for Canon or Nikon at the local sale, never mind for Sony / Minolta.  My usual purchases are classic film cameras.  But yesterday, I did just that.  A Jessops macro-kit, consisting of a Jessop MC 2x Mx/AF tele-converter, and three Jessop M-Xi extension tubes – 31mm, 21mm, and 13mm.  All with a Sony / Minolta Alpha-mount!

The seller explained that he had bought them for his Canon, not understanding the difference in mount.  He said that he had seen similar sold on Ebay for £60.  Well, I’ve checked them out, and I’d guess Ebay price for the kit might go £40 – £80.  The Tele-converter is still listed new on the Jessop website at £80.  How much did I pay?  I knocked him down to £23 (well, £25 with two movie DVDs in the price) for the whole kit.  A wee bit more than I’d spend on vintage camera equipment, but a nice buy still I feel.

Using them behind the Sony DT 50mm f/1.8 SAM lens?  Focus has to be manual – even with just the tele-converter (although it gives me the option now to use the 50mm prime as a 100mm MF prime when I need it.).  The auto focus just doesn’t find it’s target with the tele-converter behind the nifty fifty, despite claims to be AF.

With the extension tubes added, it turns the 50mm into a macro lens.  I’ve not had time yet, to experiment with different extensions or the tele-converter, nor using them with my 35mm prime lens.  D0F is incredibly shallow at macro with all tubes and tele-converter, making hard to focus anything but a flat surface (see the 20p coin below).  I’ll try for better results when I have better light and more interesting subjects, but for now I achieved the below results.

Test One. The Feather. Jessops 2x tele-converter plus all three extension tubes behind a Sony DT 50mm f/1.8 SAM prime lens

The 20p UK coin. As above, tele-converter, three extension tubes, 50mm prime lens on the A200.

The Pencil tip. As above. 2x tele-converter, three extension tubes, 50mm prime lens.

I’ll play more when I get time.  As I stated above, the tele-converter alone can double the focal lengths of my prime lenses should I need that.  I want to try the kit with my 35mm prime, and to experiment with and without the tele converter and various tubes to see if I can improve that DoF with less magnification.  I also need good light!

I don’t think that macro photography is going to be me, it’s done far better by others with better gear, but it’s worth £23 to play with that option.

Old lens on a DSLR. Top quality DoF for £25

I used my favourite lens here.  My trusty old Pentax-M 50mm F1.8.  It’s the old kit lens supplied with Pentax cameras thirty years ago.  I’m not a camera brand fanboy, but credit to Pentax for producing DSLR cameras that are so backwards compatible to old lens.  I paid £25 for this lens.  Takes beautiful shallow DoF.  Indeed, I use the same model lens on both my Pentax DSLR and my Pentax 35mm film SLR cameras.

A bit of post processing on this one courtesey of Gimp.
