DA* 16-50 or Sigma 17-50 or Tamron 17-50
Posted in Lenses for Pentax Cameras
I want to thank you all for the superb response to my quandary on this site. I posted this on a number of forums and this one has by far the most response so far ! Just to point out that money isn't the issue here but I don't see the point in putting down hundreds more if a) the lense is going to be unreliable and b) I can get something just as good (and that is the point) for half the price. I have to say I am really confused by the number of technical reports I am seeing that say both the Tamron, & especially the Sigma (exceedingly sharp), are better than the Pentax. And a number of people above are testifying that the Tamron is a great lense too. I have put this question out on a number of forums and I'm getting some great feedback - however it does seem that the SDM problems are not a thing of the past, a number of people are reporting lenses bought recently (within the last year) that have problems - and I only get a one year guarantee over here. I was almost ready to pull the trigger on the 16-50 but this issue - and the technical reports - have me spooked. Thanks again for the response and keep 'em coming !
DA* 16-50 or Sigma 17-50 or Tamron 17-50
Posted in Lenses for Pentax Cameras
OK I have made a decision on my next two lenses, the 60-250 (for a very specific purpose next year) and something missing from my range ...... one of these three before Xmas ! I have seen the 16-50 thread here and absolutely loved it ..... however I'm becoming very worried about the SDM issue. Pros though are great build quality and WR. Then I go over to the reviews here and to Photozone, SLRgear and DPR and check all the ratings / reports / comments and the numerous threads and see that both the Tamron and Sigma seem to be technically higher rated (especially on DXOmark, Pentax tested on a K20d, Tamron & Sigma tested on a 50D as the nearest equivilant). Which confuses me considering how people rave about the 16-50 (and with good reason it seems from the 16-50 thread) especially with CA and distortion better in the 3rd party brands. Then there is the price issue, over here (Shanghai) it's US$900 for the Pentax, US$330 (non VC) and US$400-450 (VC) for the Tamron and US$500 for the Sigma. That's quite a range for three supposedly very similar lenses. It must be a constant 2.8 so I've decided the reduced range (so no 17-70 suggestions please ;) ) will give me higher quality, so which one should I go for ? Is the Pentax really worth the extra money or is it just brand premium ? Note : I should mention I have the Sigma 10-20 and the 43 Ltd so this is to fill the gap.

Which lenny to pick!!!
Posted in Lenses for Pentax Cameras
Thanks for this clarification, I did think that there must have been something wrong because most of the sample shots I'd seen appeared pin sharp ( ). Apologies if I have upset anyone. So I am now coming round to the idea that the *60-250 is the way to go and for distance maybe a *300 with a TC. Thanks for your help as always folks.:) But I still have an inkling for the Bigma :oops:I don't see why you'd buy the *300 and the 60-250 unless the *300 was for commercial work. The IQ of the 60-250 is so high - right up to 250 (and it works so well with the AFA x1.7) that it makes the difference in both IQ and the extra 50mm superfluous to all except those needing the absolute highest quality. Certainly for another 1k quid !
Pentax 18-135 review at Pentaxforums
Posted in Lenses for Pentax Cameras
Thanks Simon - been there and commented :- Between these, Adam's review and other shots I've seen I think the 18-135 fails to deliver sharp enough shots for my liking and I'm going to skip it. AND (in response to someone who said : I think it is sharp enough for day to day use, I dont realy think one could/should expect too much form a lens like this...) That's the problem though - it's not really priced as a 'day-to-day-use' lense. I already have a Sigma 18-125 that hasn't seen the light of day for 6 months at least. If the 18-135 is not a huge improvement on the Sigma (I was hoping it was going to be) then I don't see the point (for me) and I would rather pay the extra and go for a DA* lense.
18-135mm DA WR
Posted in Lenses for Pentax Cameras
Not sure how this may relate to the UK/USA but over here (SHanghai) the K5 + 18-135 costs 1,200 (900 for K5 alone) so that is of course 300 for the lense.Put me down for 3 :D*sees a business opportunity* ;)
18-135mm DA WR
Posted in Lenses for Pentax Cameras
I've had a quick look and there don't seem to be many of the 18-135mm lenses on offer for any make, maybe they are so sought after that there's no spare stock. Seem to be plenty of Canons 18-135mm about, Nikons not so much. Looking at Warehouse Express, camera world and Mifsuds pricing of the Pentax lens I would have to revise my price to 600. Still, we shall see ....Not sure how this may relate to the UK/USA but over here (SHanghai) the K5 + 18-135 costs 1,200 (900 for K5 alone) so that is of course 300 for the lense.
50mm Lens 1.4
Posted in Lenses for Pentax Cameras
Thanks for all the comments most helpful. Sorry I lost the threard for a while or perhaps it was the plot (lol) but after research it was between the Sigma and Pentax and I managed to buy a Pentax smc-fa50mm 1.4 off ebay . A bit more than Still27 paid but good bargain which I'll enjoy using!Great lens ..... I love mine and I'm sure you'll love yours too !
Camera Settings Exposed !

Exposure Plot I've just run this again to see what I'm shooting (it's a free windows software program from www.vandel.nl runs fine on my Mac using Crossover). Some interesting results ! Run on my Picture folders. What an eye opener, I'd never have guessed ! 1. 17.62% @ 90 mm (guess that would be all my macro shots with the Tammy 90) 2. 10.35% @ 43 to 50mm (43 Ltd & FA 50/1.4) 3. 9.76% @ 10mm (Sigma 10-20) 4. 4.01% @ 11mm (Sigma 10-20) 5. 3.97% @ 60mm (various) 6. 3.87% @ 20mm (Sigma 10-20) 7. 3.69% @ 80mm (55-300) 8. 3.48% @ 300mm (55-300) ISO 400 - 22.72% 800 - 16.55% 200 - 10.47% 100 - 9.92% 125 - 8.86% Aperture 5.6 : 17.91% 4.0 : 13.47% 8.0 : 9.82% 1.4 : 5.50% 2.8 : 4.92% Shutter 1/180 : 12.48% 1/200 : 12.48% 1/30 : 7.45% 1/125 : 5.72% 1/80 : 5.36% Download it and give it a go !
Manual Focus Lenses...
Posted in Lenses for Pentax Cameras
Zeiss Sonnars : sorry not the man to ask, some very knowledgeable lads on MFLenses though. M42 adapters : I have 3 and luckily haven't had any of the horrible (shavings in the camera) issues some people have experienced. However I now use the Pentax made adaptor exclusively - it is the highest quality one and just takes 4 or 5 secs to put on / take off instead of the messing around for 20 - 30 secs of the 3rd party adapters.
Manual Focus Lenses...

As Dangermouse said : the 50mm & the 135mm were THE standard lenses in the film era and so there are lots of superb 50s and 135s out there. I have two MF 135s : SMC Takumar 135/3.5 - and I love this lens, maybe just a shade more than my Carl Zeiss Jena Electric MC Sonnar 135/3.5 (which I guess actually more people would appreciate) but both are wonderful lenses.

I've the Tamron 90 - fantastic lens - but to get you going in macro just reversing a prime lens (that 50mm you're going to get) will work well and just cost you a fiver for the reversing ring. Other than that go the official websites for Pentax, Tamron & Sigma and you'll be able to find the definitions for the terminology used by those manufacturers.
I may have LBA, but there are some weaknesses in my lenses, so need some assistance.
Posted in Lenses for Pentax Cameras
To me you seem to be in the same position I am - that is most ranges are well covered but now it's time to slow down, save up, and buy better quality lenses i.e. * lenses. The Pentax 60-250/4 would blow away your Sigmas and fits your budget perfectly (though I would always go Used anyway).

50mm Lens 1.4
Posted in Lenses for Pentax Cameras
If I think the light is going to be really bad ... and impossible to use flash, then I'll take the 50/1.4 for the extra half stop. However I am still in the process of evaluating the difference and haven't reached a conclusion yet !
50mm Lens 1.4
Posted in Lenses for Pentax Cameras
I have both the FA50/1.4 and a 43 Ltd. Both lenses get a lot of use, both are excellent.
Wanted - selection of lenses (along with some help choosing!)
Posted in Lenses for Pentax Cameras
You don't give your budget so although you mention 'cheap' that could have many interpretations. So I'm going to assume you have a little more for lenses than has been assumed so far. 1. Pentax DA 55-300 : wonderfully sharp and useful zoom for the price. Alternative Tamron 70-300, not as sharp, more CA but still very good and offers a real 1:2 macro too. ca. $100 (GBP60). 2. FA 50/1.4 cracking lens for the price. Alternative - if you don't mind going manual then the SMC Takumar 50/1.4 is an excellent lens for very little money. 3. Reversing ring - as has been mentioned ! True macro for a fiver. Good luck !

My wife has just found our bank statement :( Pointedly remarking on numerous EBay 'wins' :) Oops I shouldn't look happy should I ? I remarked that the last and largest of them was a package of 4 lenses and a camera and that by selling the camera and lenses I don't want, the 2 lenses I really wanted worked out at well under market ... she wasn't convinced, or even close. She hasn't found my kitty for the K5, 18-135 and 60-250 yet thank goodness !
Tamron 10-24mm f3.5-4.5, or ultra wide zooms
Posted in Lenses for Pentax Cameras
I have the 10-20 and love it. It's a great lens that lends itself to many different situations and uses. I'm sure one of my most used lenses and the only downside is the distortion that can appear at 10mm - of course this can be corrected with the right plug-in in LR and maybe Aperture 3 thought I'm not sure - there may or not be a profile to correct the distortion, a good reason perhaps to go for a used 12-24 instead) ?
FA 28 - 70
Posted in Lenses for Pentax Cameras
Got one of these and quite like it - nice range for walkabout. Mine has a rough zoom but doesn't impede shooting. Excellent lense for the money.
55-300mm
Posted in Lenses for Pentax Cameras
I have the Sigma 18-125 (versatile lense but not the greatest IQ - passable though. Never use it nowadays). I have the Tamron 70-300 (sitting in the cupboard too - has a very useful macro setting 1:2 that works very well if that is ever of use to you), I had the Pentax 80-320 (easily the worst of the bunch but still decent) and now use the Pentax 55-300 which is a step beyond any of those above and much better control of CA as well as being sharper - no question. If you are on a budget then sell the 18-125 for whatever you can get for it, then buy the 55-300, it is a fantastic lense for the price and as suggested you can easily pick up a used 18-55 kit lense for peanuts and it is not a downgrade from the Sigma you have now, most people seem to be happy with it as a kit lense. You then have 18 - 300 covered by good lenses.

Posted in Lenses for Pentax Cameras
I have both the FA 50/1.4 and the 43/1.9 Ltd ...... and the 50 is on the camera more than the 43. Only half a stop difference but that means you can shoot at 2.0 and it's sharp ith great bokeh. For the money no question. I love both but unless you are loaded go for the FA 50 and put the rest towards another great lens.

Even then it may be still worth buying from the US as it is $599 dollars (list) there.Than you add, shipping costs, import tax and VAT... I don't think it's worth it.It is. The cost is not as much as you would think. Firstly let's look at how much it costs to have the lense sitting on the dock. If we use the US$ price as a base then we can assume a CIF price of maybe GBP200 (US$300 with the remaining $250, of the MSRP US$550, going to cover mark-up and in-country transportation cost). Add VAT at (currently) 17.5% (GBP 35.00) and the Import Duty on lenses into the UK is just 6.7% (GBP 13.40) so you now have your lens legally imported (and you can claim back the VAT if you are registered) for just GBP248.40 . Mark-up in the USA was ca. US$250 and in the UK GBP351.50 . Alternatively you can buy one direct from the USA : Cost of lense : $550.00 (seen advertised - could end up being lower) Transport (ca.) $40.00 Insurance (ca.) $10.00 VAT (@ 17.5%) : $96.25 Import Duty (@6.7%) $36.85 In your hand US$733.10 or (at 1.5 : 1) GBP488.73 . And that's assuming the Customs pick up on the lense in transit, they may not, and no discounts on purchase price in the USA (and again you can claim back VAT if you are registered). A GBP110 saving off the bat and could be a lot more depending on your VAT registration, US discounts and C&E vigilance ! True - your warranty will be a US one but return postage isn't much and how often do we need to return lenses ? I haven't ever, not once and I have quite a few !

I've just picked up the Tamron 500 BB off EBay but don't have the Adaptall Pentax mount yet. However those shots from Jon are inspirational and I'll have to go and find that mount soon !
