12-24mm or 15mm
I also agree, the Sigma 10-20 is well worth a look. I bought mine after much research back when the 12-24 didn't cost a million pounds. Now the 12-24 is so much more expensive it should be an even easier decision :D Not sure what Flossie is referring to, the 10-20 seems pretty well built to me, a...

Vivitar 75-210 f3.8 close focus lens
I don't think you can go wrong for a tenner. Vivitar had a decent reputation in film days, although I've no experience of their lenses. I am intrigued by the lens they did with a "matched multiplier" teleconverter, although I don't know much about it. Try typing the lens details into Google and ...

16-45 or 17-70?
Bearing in mind I'm a Landscaper and will hopefully soon have a 12-24mm again!). I want to go back to Zooms, I bought the DA Ltd's to teach me better shot discipline and I think I have now learned my lesson, so time to move on... So to go in between the 12-24 and the 50-135, which is best opticall...

16-45 or 17-70?
I recently owned a 16-45 and it was terrible, maybe just a bad copy. sent it back and got the Sigma 17-70mm 2.8-4 DC Macro and it's superb.

16-45 or 17-70?
I have both :D The 16-45 is much lighter than the 17-70. Optically, I much prefer the bokeh on the 17-70 (it is very smooth and similar to the 50/1.4 and 24-90). The 16-45 is a bit too busy for me. But that's personal opinion. The 16-45 zoom mechanism is interesting. It extends at the 16mm en...

bringing the right lenses to Mauritius island!
Just an explanation as to how l approached a similar problem. What lenses to take, what lenses to take ?. OK so at the time it wasn't Pentax kit, but l don't think that is relevant in relation to the question / answer. In the end l took one - 28mm f2.8 prime. Photographically it worked out...

Tamron 70-200mm f2.8 and 2x
I have a Tamron 70-200mm f2.8 and just bought a kenko/teleplus 2x MC7 DG to use for the odd bird shot or similar - thinking more record shots than keeping the best quality. Unfortunately it just won't af - tried for a bit but the af just swung to infinity and sits there buzzing. I've tried it on my ...

Tamron 70-200mm f2.8 and 2x
Hi Sue, I won'i be much help here sorry. I don't own the Tamron 70-200 f/2.8 but have 4 TC's, 2 of them are Teleplus SHQ models 1.5x and 1.7x and work well with DA*200 and DA*300 SDM lenses although they tend to hunt a little depending on conditions. I have a Teleplus 2x MC7 (not DG) this will not w...

Tamron 70-200mm f2.8 and 2x
OK - had another play although the sun has now disappeared which does'nt help! I gave the Tamron contacts another clean but the result is the same. What I did'nt notice before is that the viewfinder info includes a flashing 'mf' when you try to focus so it definitely does'nt seem to work. I've tried...

Tamron 70-200mm f2.8 and 2x
Have you set the Tamron to AF by pushing the focus ring forward?

Tamron 70-200mm f2.8 and 2x
Yes - remove the tcon and fit the lens back onto the camera and the af is working perfectly. However, what I've also just discovered is that it is in fact impossible to mf with the tcon on as the focus ring is locked even when set to mf - with the tcon on mf is impossible in all settings and af just...

Tamron 70-200mm f2.8 and 2x
The markings on mine are Pz-AF 2X TELEPLUS MC7 KENKO DG - it sounds like it's a fairly modern design as it has DG on it. It definitely zips along on my HSM lens but the lens is too slow for a 2x and struggles to lock focus. Oh well - I suppose I'd better cut my losses and put it in the classifieds...

k 50mm 1.2 vs. A 50mm 1.2 lens
M is fully manual, where A will allow you to use the semi-automatic modes (Av, Tv, etc). Both are manual focus.

k 50mm 1.2 vs. A 50mm 1.2 lens
The Sigma 24mm Super-Wide II f2.8 is a fantastic lens, it's one of my favorites. I only paid £30 for mine, and I think it is sharper than my smc 50mm f1.4. It's an A lens so works in AV etc.I have a manual focus one but I believe there are auto-focus versions as well.
