First up is a Tamron SP400mm LD-IF F/4,

Great optics, aperture working correctly. Cosmetically has been covered in a Carbon fibre vinyl, and the focus grip looks to have been removed and put back on, as it doesnt quite join. The focus ring was working very smoothly up until a week ago, but now feels a little gritty. Nothing drastic, but I noticed the difference compared to how buttery smooth it was before.

Photos are on my phone, so will add these later. Asking £350 to include a 48hr insured, tracked parcel service.


Next I have a faulty Tokina 20-35 f/2.8. I bought this to eventually use on a K-1, but decided against going full frame, and sold it to a member on here. Unfortunately it was found to be faulty and I took it back. I have done a test on it and can say that it does have front and back focus issues which I will now explain.

@20mm 1.4M distance....F/2.8 correct, F/4 correct, F/5.6 correct, F/8 correct
@24mm 1.4M distance....F/2.8 correct, F/4 correct, F/5.6 correct, F/8 correct
@28mm 1.4M distance....F/2.8 correct, F/4 correct, F/5.6 correct, F/8 correct
@35mm 1.4M distance....F/2.8 correct, F/4 correct, F/5.6 correct, F/8 correct

@20mm 1.9M distance....F/2.8 Back Focus, F/4 correct, F/5.6 Back focus, F/8 correct.
@24mm 1.9M distance....F/2.8 Back Focus, F/4 Back focus, F/5.6 correct, F/8 correct.
@28mm 1.9M distance....F/2.8 Back Focus, F/4 correct, F/5.6 correct, F/8 correct.
@35mm 1.9M distance....F/2.8 correct, F/4 correct, F/5.6 correct, F/8 correct.

@20mm 2.4M distance....F/2.8 correct, F/4 correct, F/5.6 correct, F/8 correct.
@24mm 2.4M distance....F/2.8 correct, F/4 correct, F/5.6 correct, F/8 correct.
@28mm 2.4m distance....F/2.8 Back focus, F/4 correct, F/5.6 correct, F/8 correct.
@35mm 2.4m distance....F/2.8 Front focus, F/4 Front focus, F/5.6 front focus, f/8 correct.

Infinity was successful 95%

All shots were taken without any micro adjustment, and Auto refocusing between each shot to help me determine acuuracy.

I can upload all test shots for you to study on drop box if you want, just P.M me an email. So basically You have an all focal length F/8 20-35, or drop the 35mm and you have a F/5.6, or even a lovely ornament

Gutted to say I paid £250 for this, and not needing it now, im losing a lot of money....£120 including delivery and it's yours.

If it wasn't for another recent spree of purchases I'd be all over this. Guys, if you want to use this lens properly, just hit the liveview button and get perfect focusing everytime on every f-stop!

Let me know if it's not gone by the weekend. I'll take it off your hands.
