Lens suggestion anyone?
Thanks for all the replies, interesting link Frogfish! 24-90 sounds like a very useful range, and if it's that good then the f4-5.6 should be OK, if I can use it wide open. I am off back to Doha shortly (in Japan at the moment), and will hopefully make a decision tomorrow; I hope the 24-90 is still ...

Lens Selection
Any of you guys out there got a DA 17-70 AND a DA 18-135? How do they compare in terms of image quality and speed/quietness of auto-focus? I bought my new K-5 body before Christmas and now I'm looking for a standard "walkabout". I was tending towards the 18-135 until I read the various comments a...

Wide angle prime k mount for Pentax MX?
I am looking for secondhand wide angle prime (24mm?) for use with my Pentax MX with slides. Any suggestions? Vivitar, Tokina, Cosina, Bell & Howell, etc.? I would prefer focus action to be same direction as Pentax 50mm and 80-200 I already own. Subject matter is mainly Scottish landscapes.

Wide angle prime k mount for Pentax MX?
The Sigma mini-wide is 28mm, and reputedly very sharp. The Sigma super-wide is 24mm and is excellent, I have the AF version & had the MF version. Focus is the same direction as Pentax lenses. The AF version is better built but larger. I have yet to use it on my MX, but I certainly plan to. ...

Standard zooms comparison (DA16-45, DA17-70, FA24-90)
As a PS, I eventually sold the 16-45 as there didn't seem to be any real advantage in having both that and the 17-70. Unexpectedly I'm using the 24-90 more than the 17-70; looking back over the past year, just over half my shots were with the 24-90, a third with 17-70, and about 10% with 55-300 apa...

SMC Pentax-DA 18-135mm WR
No stereo photography, but Sue and I went to Mere Sands Wood and Martin Mere yesterday. A couple of images from the 18-135mm are now in the PU gallery and more will follow, plus more on ePHOTOzine of course. Both lenses are fine, focus quickly and silently and perform exactly as expected. At £299...

SMC Pentax-DA 18-135mm WR
Just Got back from Scotland and have had the 18-135 on the camera most of the time. I have only had it for a couple of weeks, recent price drop finally persuading me. I have been using the 18-55 and 50-200 wr lenses for mountain trips lately, mainly as I want to be able to take pictures when ther...

Test for Zooms
Newspapers pinned to a flat wall would be OK, but bear in mind that zooms may exhibit field curvature so centre and edges may not focus at exactly the same point. Real 3D images are also needed as this is what we use lenses for. Over a period of time we get a feel for whether we like a lens or no...

portrait lenses
The classic portrait lens on film would be 85mm (so the equivalent would be the SMC Pentax-DA* 55mm f1.4) to 105mm (Equivalent would be SMC Pentax-DA 70mm f2.4 Limited) but some prefer 120mm (equivalent would be SMC Pentax-FA 77mm f1.8 Limited). I used to use the 100mm on film but currently have ...

Lens Caps and Lens Hoods - LensHoodCaps?
What for? It depends on how you work, but the essential thing is that the back element and contacts are protected and the front element doesn't get scratched in the bag. In practice, under wedding shoot conditions, hoods stay on and back caps are always used. In slower shooting where lenses are n...

What is your favourite Pentax Lens
Pentax-A 50mm 1.7 was my favourite but now I have the FA 50mm 1.4 i think I will be happier with not having to manual focus all the shots ! not had much of a chance to take photos yet this year though :-(

What is your favourite Pentax Lens
My fave tends to change every few months. At the moment it's an smc-A 50mm f1.4 which I've just had serviced and generally reset. It's a joy to handle now and something about its rendering makes it great for black and white street shots, quite open so plenty of the shot is out of focus. No idea w...

What is your favourite Pentax Lens
My favourite to use is the K85/1.8; beautifully engineered and I don't know why, but it always seems to give pleasing results. The FA50/1.4 was almost too perfect so I sold it in favour of a Tomioka 55/1.4 That's interesting - I never really got into using my FA50/1.4 either. Although it's an ...

35-70mm macro
Bought a Pentax smc version, last week for a tenner. They are nice little lenses. Manual focus. Not true macro lens but close focusing. Obvisiosly equal to 52 - 105mm on digital. Great little lenses and cant go wrong at very little money.

35-70mm macro
I bought a SMC 35-70F lens a week ago in a secondhand shop for $AU35.- I had a look at some revievs on the Internet. Most revievs where in favour, but most the complaynts where about the mechanical part. Some said the focussing ring was to sloppy, others complaine bout the plastic feel. The lens I...

Relationship between lens sharpness & sensor size.
I've found the DA 35 2.4 AL to focus faster, and to have sharper corners (surreal even) than the kit lens. I also like how small it is, and very light. Certainly a good walk-around lens that makes you think for the shots you want to take, in the process coming up with something creative.

Relationship between lens sharpness & sensor size.
The problem is, the kit lens is respectably sharp stopped down, and 35mm is its sweet spot! You're probably right that any difference would be more pronounced on a higher resolution sensor. However I don't buy primes primarily for extra sharpness - wider *usable* maximum apertures, small size and ni...

Relationship between lens sharpness & sensor size.
If your lens is genuinely 'duff' you should be able to take it back to Jessops, no bother. Stick at it for a bit though. Try it for some wide aperture portraits for example. If it's missing focus, try manual or live view focusing... If that gets you a better result (neither are affected by front or ...

Relationship between lens sharpness & sensor size.
Thanks Jak, I have found the site difficult to use for lack of instructions. I don't have access to a web depository and the Gallery isn't intended for this purpose so I shall not be able to show you the test images. The new 35mm lens is sharper in the corners and does show better bokeh but for m...

Leica R on K5 compared to FA Ltds?
I could go down the route of fitting an adapter to each, but at about £60 a throw its not a cheap option for MF lenses Maybe just buy one adapter and make your lenses share... Do the adapters allow for infinity focus?
