Pentax WR lenses
I guess you really would have to have a specific need to buy a WR lens at these prices given that the non WR versions are currently being offered by SRS for £49 & £99. From my direction I would not consider them. I already have a DA*16-50 which is weather sealed and I specifically used in falling...

Superzoom versus K7 kit lenses and options!
Hi there, I went on safari trip to Botswana earlier this year and took the K20D: very happy with it. I currently have the 18-250 (Tamron flavour) which is very good at what it does, but I wouldn't take it on a safari - you don't want to come home with pictures that could have been stunners "if...

who sells in singapore
I go a couple of times a year and my DA 12-24 came from in Peninsula Plaza who I'd very happily deal with again. At the time (2007) it was significantly cheaper than the UK - not to mention actually available. But since then the UK price has fallen (OK so it's going right back up again:-(), th...

Pentax 17-70 versus the Sigma 17-70. Quick user experience required.
I am waiting for a Pentax 17-70mm weather sealed lens, I reckon they may well make one pretty soon to accompany the K-7. Although the Sigma is a good lens (sold mine a while back) I would prefer the constant f4.

Maybe a silly question..........
Hi Lynton I can't understand why you sigma 70-300mm would be disappointing at the 300 end.When i owned one i had some excellent quality images at the 300macro end. Advancements over cheaper kit lenses would be speed i.e f2.8 as opposed to f4' less chromatic aberrations' better quality glass and ...

Kit Lens v 16-45, opinions please
The 16-45 fully wide and wide open is noticeably better than the 18-55, but in extreme circumstances it suffers from chronic CA. For the most part I cant see any difference, eg at f8. The wider angle is useful. I have to say I was quite disappointed, from what others said I was maybe expecting too m...

SMC PENTAX-A 35-70mm f/3.5-4.5 MACRO ZOOM LENS
Does anybody have one and what do they they think of it? I just picked up one on ebay for £17 plus £9 postage to Spain so if it gives reasonable results I'll be quite happy. Here is a photo of it, looks in good nick, hope to have it next week, one touch zoom and focus.

SMC PENTAX-A 35-70mm f/3.5-4.5 MACRO ZOOM LENS
The IQ is not stellar, with some distortion down at the 28mm I just realised the mistake in my original post, the distortino does occur at the wide end, but obviously not at 28mm. :oops::oops: for the price you paid Jack you probably got a bargain. The zoom slides on 2 nylon bushes secured to...

Takumar M42 f/4, 17mm "fisheye" lens
If it is the SMC version, which it should be if it has the open aperture metering lever, it was manufactured 1971-1975, 11 elements in 7 groups, Min Focus 0.66 feet, 230g weight. It is said to be very sharp and contrasty, unlike earlier fisheye designs.

Sigma 170-500mm
A couple of months back a friend of mine took a punt on a DA*50-135 (against my advice) on eBay. It was a zero feedback seller using a stock photo and no wording other than "Pentax lens brand new". I was convinced it was going to be a scam, as did everyone else as my friend was the only one who bid ...

Macro experimentation pointers
Thanks guys, yeah the 28 on the 50 was my first plan and i'll take it from there. Obviously the choice of lenses above wasnt intentional, just what came up in a suitable auction (pleased because i wanted a 50/1.7 anyway and they seem to make £40 so the rest of the gear for £30 odd quid is a major bo...

Macro experimentation pointers
Mike, the reversed 28mm is a lot easier to use than stacking it on another lens. I was composing wide open by pulling down on the aperture lever on the front (back) of the lens and releasing it when taking the shot (black viewfinder otherwise) I had the aperture set on 22 and used a flash off came...

Pentax/Tamron 18-250
But you've already got the 28-200, alright it's not quite as wide or as long at the ends but it's not a million miles away (or a couple of steps back and forward to be more accurate). Each to their own though and you know your needs better than I... :wink:
