The old chestnut: 16-45? 18-50? or even 15-30 with 28-70
Do any rectilinear wide angle lenses at all come for that sort of price? The major downside of APS-C is that wide angles are expensive. Probably the most cost effective option for wider than 16mm is the Sigma 10-20, although there is a Zenitar fisheye that's not too expensive - it requires post-proc...

Old sigma 100-300
Its just im taking a trip with my parents to Ras Al-Khaimah, one of the emirates in UAE about an hour or two outside Dubai. I want a reasonably long lens but on a budget, since ive just bought my fisheye. I was looking at the 50-200mm, is this tamrom 70-300mm a better option? Or would I be better of...

Old sigma 100-300
Oh and also, how can I tell the difference between an autoexposure lens and a manual exposure lens? Mostly by the model name. Most auto-exposure Pentax lenses are prefixed with "A", "F", "FA" or "DA". Also look out for the actual "A" setting on the...

Macro Lens
In addition to Matts fine suggestions if you're looking for second hand and don't mind manual focus then the Tamron SP adaptall lenses usually offer very good value for money and come up often on a certain well known auction site. I use one myself with very satisfactory results. I got mine with a...

Macro Lens
There are a few cheaper options you might want to consider as well: 1) Manual focus lenses - there are lots of these pretty cheap, including Pentax ones. Manual focus isn't a problem for macro shooting (it's more reliable than AF anyway) however it might limit the lenses usefulness for general pu...

Macro Lens
Why not look for one of the Pentax manual focus macro lenses. Good though the Vivitar and Tamron ones may be, the Pentax ones will be better and more compact as well.

Macro Lens
Correct though John may be (I've never used a Pentax MF macro lens), the Tamron SP 90mm is superb and a lot easier to find. Don't get me wrong, if you can pick up a Pentax then go for it, but don't turn your nose up at an "off" brand because you're waiting on the Pentax, because you mig...

Macro Lens
I've just seen that a Vivitar Series 1 90mm macro lens has appeared on e-bay. I think this is the one I remember, goes to 1:2 native and 1:1 with adapter. The dealer's blurb suggests it's a star product but there are lies, damn lies and .... I don't know that one - all the manual focus Vivitar macro...

Pentax 12-24
I've yet to hear a bad word about either lens, which makes it unlikely that you'll find anybody who's bought one of them and then moved on to the other. This means you'll struggle to find anyone who can give you a meaningful comparison between the two unfortunately... For what it's worth, before ...

Pentax 12-24
Not a comparison, but I can tell you that the Pentax 12-24mm is a cracking good lens with outstanding optical properties. It also has very, very low distortion making it suitable for architecture. £489 will get you one compared to £429 for the Sigma. £429 would be very expensive for the Sigma - ware...

Pentax 12-24
depreciation is the acccounting thing...but we do sell off our used gear, (computer and photo/video) and replace on a regular basis....so resale affects bottom line. We are small. Incorporating is due to multimedia content creation, not family portraits...Heck if it was feasable, I'd rather rent eve...

no budget tele question
For what you'd have to spend on a half decent converter you'd be far better off looking for a second-hand longer lens, the Pentax 80-320 for instance, also have you considered manual focus? you should be able to find a 400mm K mount or even KA mount for a reasonable amount. There are plenty of th...

no budget tele question
Thanks for that ! Point taken about TC cost I'll look out for that 80-320. Should have mentioned Ebay is out as I haven't got a credit card :) The market in NZ is very small though prices of second hand stuff seems quite good. A 400 m42 came up a while ago but I really want stop down metering. ...

F 70-210mm vs DA 50-200mm
I have both, the 70-210 is very very heavy and is well balanced on the SFXn that it was designed for and not so great on a dslr. It is sharp but the contrast is lacking compared to the 50-200; as has been said it benefits from a hood and the correct rubber one folds back over the lens for storage, a...

Is it worth fixing a sticky aperture ring on a 50mm A f1.7?
The problem with your aperture ring sticking is likely to be a small metal part that was weakly bonded to the lens by the use of plastic. This metal part, when it works itself loose, causes this 'sticking' problem and can eventually stop you turning the aperture ring past f/11. A small screw and som...

PKA Old Lens 28-200mm on K10D
Hello from Portugal I recently bought a really cheap manual focus lens to complement my pictures. It is a Sirius 28-200mm for the K1000 camera. And the seller told me that it would fit the digital models such as the K10D. So I've received it yesterday, it's in imaculate condition, but it do...

PKA Old Lens 28-200mm on K10D
This is a common reason why older K-mount lenses don't fit. It's the black flange that runs alongside the stop-down lever - on many lenses, it's FAR too long, and collides with the inside of the camera (or, in worst case, the mirror). Remove the offending ring (it's usually unscrewable or just li...

Not a great pic I know but one to check the focus, of which I am not sure. Is this acceptable for Sigma 10-20mm
