Poll about the DA 18-135 WR

I have it. Have to say I enjoy using primes more for general shooting but the main thinking for this lens is that I do quite a lot of skiing and, matched with a K7, it looked like a good set-up - solidly built, compact, wide enough range to cover scenics and action and fast focusing for the latter....

Poll about the DA 18-135 WR

I voted yes. Most people who actually own the DA18-135 seem to like it. Those who do not tend to be heavily influenced by the photozone review which gave it a very low score because of softness at the borders and vignetting. My copy is very sharp in the centre of the image which is where the m...

yashica to pk converter

I don't think you can and keep infinity focus as the registration distance is different. If anyone makes one, SRB Griturn will. K.

yashica to pk converter

Sad to say I doubt they exist, at least for sensible money and without glass which tends to degrade image quality. The only adapters I see are for the M42 screw mount lenses, as this mount is small enough to fit inside the K mount and therefore allows an adapter which won't affect the distance fr...

yashica to pk converter

I assume you mean the Contax/Yashica (registration distance 45.5mm) rather than the rarer Yashica Pentamatic, Pentamatic II (registration distance 43mm). As others have already said infinity is likely to be a problem unless the CY mount fits inside a PK (~0.04mm is not much to play with but even ...

Waxing lyrical about FA 135

:evil::evil::evil: :oops::oops::oops: So, you hate it then. Want your money back? I offer 24 month returns policy on FA 135mm lenses if not totally satisfied (less postage of course), and your in luck, it hasn't expired yet. :lol: That's about the only lens I regret selling. That, and the K...

50mm Lens for my K-r

Well the M50mm f1.7 isn't bad if you don't mind manual focus and 'green button' metering, very cheap. Next up is an A50mm f1.7 which additionally gets you the usual camera metering modes,

50mm Lens for my K-r

If you go to carboots you can sometimes pick up a smc pentax-A 50mm lens up for about £5.00 ( just check for fungus and sticky aperture blades)or you can get one from eBay for around £50. 35mm ones are very rare even on eBay, but a nice smc Pentax-A 28mm will only cost you about £70 and will give su...

50mm Lens for my K-r

What is the price of the F.1.4 lens? thanks Bobby Double the 35mm Edit: Should add that's a FA f1.4 AF. An old manual M series 50mm 1.4 will set you back around £80/100.

Pentax fa 1.7 50mm

Got hold of the above lens for my K-R (my first prime) but am not happy with the sharpness/fine focus particularly below f2.8. I have tried adjusting focus in camera settings but it makes no difference. Is this because older lenses don't support this? Not sure now if i should sell it and get the new...

Pentax fa 1.7 50mm

It should work/focus fine on your K-r. What have you compared it with? Could you post some sample shots?

Pentax fa 1.7 50mm

If the camera isn't finding focus with the f1.7 then it's likely to be even worse with the f1.4. Is any point in the images sharp? I'm just thinking the camera may be locking focus on a point other than that which you intend, and at f1.7 that's a very tight distinction.

Pentax fa 1.7 50mm

If the camera isn't finding focus with the f1.7 then it's likely to be even worse with the f1.4. . Well that's true, but the point is to calibrate the AF. I have a FA 50/1,4 and a Sigma 30/1.4 and I've calibrated the AF on ech and it works fine. You cannot rely upon the standard focus scre...

70-200 Macro £600 v 70-300 Macro £100 or 150 macro?

I've been using a Tamron 70-300mm lens with macro for butterfly shots. I'm now considering various options with vastly different sums of money involved! 1. Get the lens repaired for £80. 2. Buy the Sigma 18-250mm for £400 - I could do with a doitall lens and I believe this does close focus so ...

70-200 Macro £600 v 70-300 Macro £100 or 150 macro?

Be careful with IF macro lenses they are 150mm or 180mm at infinity, at 1:1 they will only be slightly longer than a 100/105mm macro (the FL become less as you focus closer). There's a thread about it on the US forum. I think there was only 7mm difference :cry:

Sigma macro for K-x

I presume you mean this, Trixie: Providing it is the K-mount version, it will work with your K-x (Av mode) focussing will be entirely manual: not necessarily a bad thing but something you need to be aware of. If the crop factor of the K-x sensor is taken into account (approximately 1.5x), it wi...
