How you supposed to squeeze it into that little case, or is it telescopic? That is the lens cap :wink: There were a few of these long lenses on ebay a while back, all mint but engraved with Israeli army markings. Not the kind of things to take certain parts of the world.

500mm len's
I have the old Tamron but I wouldn't say it's very good optically. It doesn't seem all that sharp and is of very low contrast. Mechanically it's a pleasure to use and is very handy as it's so small. Very smooth focusing, very good close focus and the tripod collar makes it easy to mount and rotat...

2nd hand Macro Lens for K100d
Here are some pointers: 1 Forget zooms. The best lenses for macro are primes (lenses whose angle of view is fixed). 2 Forget auto-focus - it's not necessary. This means you can happily use lots of older lenses. 3 If you can't afford a proper macro lens (like the Pentax D-FA 100mm macro...

2nd hand Macro Lens for K100d
You might also want to look for lenses that have a 1:1 macro focus. This basically means that at the closest focusing distance the size of the image will match that of the object. Otherwise, extension tubes or reversing rings. You could also look at something like the Raynox DCR-250 which some peopl...

2nd hand Macro Lens for K100d
Hi all i've been lurking for a while and reading all the great tips. I'd like to get into the macro world a bit more... i have the tamron 70-300 which is ok, but the min focus distance can be a tad annoying on macro. i know nothing about bellows and extension tubes and, quite frankly, they ...

2nd hand Macro Lens for K100d
i know nothing about bellows and extension tubes and, quite frankly, they scare me! There is absolutely no need to be scared of extension tubes. All they do is move the lens further away from the camera, which effectively moves the point of closest focus closer to the lens, which means you get a ...

2nd hand Macro Lens for K100d
ok... i have got a 50mm 1.7 on the way as well as the extension tubes (it was me who won them on ebay, Chris!) All packed up - I'll try and get them into the post today. :) I must admit, I expected them to go for a lot less than that! :oops: one more question... how do extension tubes/bello...

2nd hand Macro Lens for K100d
cheers for that... maybe i should have mentioned that i don't like spiders! the only other tubes i saw were a lot more than yours... so i was happy. the lens was good value too, so it's cheaper than buying a specific lens by a long way. i used to have tele-converters back in the film days, but...

2nd hand Macro Lens for K100d
I started off on macro with extension tubes and then bought a cheap Vivitar 55mm F2.8 Macro which goes to 1:1 and is surprisingly sharp. The only downside was that it's manual focus (although that's not a big deal with macro) and it didn't have a "A" position so it didn't work quite as well on my K1...

2nd hand Macro Lens for K100d
the great thing about true macro lenses (read prime lenses which focus to at least 1:2 without any extra adapters) is that I've never heard of a bad one. Some are better than others, but even the cheapest of the cheap like niblue's Cosina are optically very good.

Bit of a quandry.
[ Very cheap indeed, I have seen several go for under AU$300 of late on E-bay if you are looking second hand. How you finding the 18-250mm? There is a mint one on Ebay for under £200 delivered that I keep going back to. Might be ok as a walkabout lens and get rid of the 24-135mm

Pentax 300 or Sigma 70-200 f2.8 plus converter
The Sigma 4.0/100-300 will auto focus with the 1.4 EX DG Converter. When using the 2.0 EX DG Converter you will lose AF. Probably the same goes for the EX 2.8/70-200. Martin. Edit, beat by a second :lol:

Pentax FA 80-320 test shots
I'm selling this lens for a friend (its in the classified section) and decided to give it a run to see how it performed. I was quite impressed with its performance especially in low light. All pics straight out of the camera no processing. This was taken in pitch black leaning over my balcon...

Pentax FA 80-320 test shots
Apart from the softness at the long end, which as Peter says, is forgivable, the thing that put me off about it was difficulty getting it to focus. Admittedly I only had it for a short time, but several times it hunted like crazy, even in good light with contrasty subjects. I compared it at the ...

Pentax FA 80-320 test shots
The 55-300mm looks attractive as a proposition and we may well end up going for that. How close does it focus?

Pentax FA 80-320 test shots
The 55-300mm looks attractive as a proposition and we may well end up going for that. How close does it focus? 1.4m (4.6 feet) is the marking at the end of the scale.

The 55-300mm looks attractive as a proposition and we may well end up going for that. How close does it focus? I am interested in this lens also but i don't want to pay over AU$600 for it here in Aust. :cry: Whats the best price you are getting in UK for it:?:
