I agree with that edit to the thread name, that is if it can be done.

I can't see another Ltd zoom ever coming out and if indeed one does appear far in the future sure the thread name can be renamed but we shouldn't be worried about this whatsoever.

Damn I haven't used my 20-40 in 6 months because I have only been out once for a northern lights capture for which I used the Samyang 14mm f2.8

:(

Hopefully I'll be using it again in earnest soon. :eek:

I've been editing RAW photos taken with my K-30 and DA 18-55 kit lens that I lent to my mother for a holiday in Singapore, Cambodia, Thailand etc. for the past few weeks. I recently got the kit lens for free with a cheap broken donor *ist DL2 camera I bought to salvage the white solenoids from it to replace my K-30 green solenoid.

This is the first time in years I have seen images taken with the 18-55 as I sold mine years ago and I have only used my trio of DA15, DA 20-40, F* 300 f4.5 and DA* 60-250 for the last few years.

The DA18-55 absolutely sucks compared to good lenses, I'm not talking about sharpness as I'm not a beginner photographer, it is sharp enough but the real qualitative measures that an experienced photographer will judge a lens on are woefully lacking. I feel people who judge a lens by sharpness years on in photography have not moved up from rung 1 on the experience or talent ladder, sharpness in lenses is never a problem and it comes in as a trivial consideration in my judgement.

Lack of 3D pop, 'flat' images, poor contrast, poor colours and colour saturation, lack of micro contrast etc. etc. The images just did not look good and I have spent weeks in Lightroom trying to get a nice photoset from the DA18-55 images.

It was a real shock when 'going back' to a kit lens like this from being used to Limiteds and * lenses which just make much more delightful punchy images and need far less post processing.

The likes of DA 20-40 Limited is in a completely different league to 18-50/55 kit lenses. It is a rare occasion where a lens outperforms expectations which is what exactly happened to me when I seen the images for the first time I used it.

Kit lenses are perfectly decent for learning with like I did or for a jpeg snapper but then why bother owning a DSLR? :)

I can't see there ever being more Limited zooms so I'd support a thread name change or a new thread.

This lens deserves it's own thread regardless.

The hacked firmware is a treat for K-30, I installed it years back and there are zero problems, infact the camera is more stable as the K-50 firmware must have ironed out more bugs. My K-30 used to crash now and again with firmware 1.06, the hacked K-50 firmware fixed that. Go ahead and install it even if like me you don't own KAF4 lenses :)

My K-30 has a white solenoid too :)

Using moulded aspherical elements introduces a new problem of onion ring bokeh. Ground aspherical elements are better but very expensive to make. I think Sony have a new way of making aspherical elements but these are only used in expensive G-master lenses however I'm no expert on Sony gear.

He said so back in 2017 then a few hours ago on dpreview in a big long thread about the 70-210 f4 he said otherwise.

Don't be surprised if all the new lenses will be clones, we all thought the 70-210 f4 was going to be a new Pentax in house design.

No plans to replace existing lenses like DA* zooms according to the mystery man as elusive as Bigfoot.

I would take him with a pinch of salt as he has been wrong before.

Photogem, for those cameras that use a solenoid in the flash requiring batteries and power...

You can slide in a thin piece of plastic under the flash to operate the lever and pop up the flash. I had to do this as my donor *ist DL2 didn't power on and I had no batteries anyhow to put in it. You need to pop up the flash in order to take the camera apart to retrieve the white solenoids for transplanting.
This method is also safer as you can leave out the batteries to allow the capacitor to slowly discharge before you open the camera.

I think you are asking me? Well yes it is from the flash. On the *ist DL2 the camera needed to be powered on to pop up the flash, it seems like a bit of over design but hey I have it for a spare in my electronics box :)

Although I love metric and liked teaching measurement, Base 12 'dozenal' has the advantage of being divisible by more whole integers to return whole integers than Base 10.

I had a book containing the history of this stuff when doing my teaching diploma.

I'm past being interested but there are dozenal promotion societies if you want to read more. ��

Fixed my K-30 today with a white solenoid from a *ist DL2 donor camera. I spent as much time getting the two white solenoids out of the donor and felt the need to put it back together for some reason?

I counted 27 screws excluding solenoid screw.

It is so easy to unsolder and solder the wires whilst the solenoids are attached to the camera, don't bother soldering wires then heat shrink etc. there is no need.

I used hot melt glue on the reattached white solenoid screw as insurance and on the pink/purple wires to hold them neatly in the original position where sticky tape held the wires.

Weird the green one failed, it seems to have the same pulling apart force as the white solenoid. There was no rust on the plunger, it looked in great condition and the solenoid was parallel also.

There is loads of play in the white solenoid also but the white PTFE definitely has less friction when you pull out the plunger at an angle.

Now I have a spare white solenoid should my K-70 ever go bad, you get 2 of them in *ist DL2 :)

The resistance of the white solenoid read 29.8 ohms and I read 28.6 ohms from the failed green unit I removed.

Well done! I need to do mine within a week so my mother can take a K-30 on an exotic holiday with her, just using a 18-55 kit lens on auto settings. I even got a Sandisk Extreme Pro 128GB card for her so she can use RAW and I can edit the images.

The blobs of blu tack are a good idea, mixing up screws is a no no and simple methodical methods like this eliminate the danger.

I lusted after this lens for years when I couldn't afford it..

I should have gone into debt to get it earlier :p

Good attempt and nice composition/location but 1sec is beyond IBIS, using f8 here would have allowed 1/4sec and very possibly a non-wobbly photo depending on your wobbliness :lol:

I've did 4sec "handheld" but rested on a gatepost and got a sharp nightscape with Samyang 14mm @ f2.8

A monopod is even good with the camera forced against a tree :)

Interesting to hear of the return to the DA* 50-135 from DFA 70-200 but no surprise given the bulk and weight of the latter.

The DA* 50-135 f2.8 has become very cheap on the used market. A fully working copy (SDM still works) got no bids at 199 on Ebay last week... 199 for this lens is insane and I would buy one except for buying the DA* 60-250 f4 this year.

I already had the Samyang 14mm f2.8 and whilst sharper over the whole frame, faster and sharp at f2.8 it had significantly more 'significant' weaknesses than the DA15. Lens flare, distortion, colours, rendering, sun burst shape, size, weight, close up ability and every other lens quality were significantly worse.

DA15 has pixie dust and buckets of it, I bought it for a photography holiday down the west coast of Ireland which is photography paradise and managed to nail some of my best ever work and haven't left the house without it since.

I only use the Samyang for astrophotography which it is great for and the weaknesses don't really matter.

Shows the reason why you may need 2 prime UWA lenses, one for day and one for night with different specialisms.

You could have a DFA 15-30 that does both but then a massive weakness shows up, that being the huge beast it is.

A Canon shooter thought I was using a compact camera up the mountains when it was K-30 & DA15, he couldn't believe it was a DSLR and UWA. :lol:

Rayallen has learnt the best way to use it and where to focus it. You can find discussions exactly like this one online going way back to when the DA15 came out.

For anything other than close ups (where I want OOF and bokeh besides thd main subject) I use manual focus and magnified focus peaking in Liveview checking focus in all areas like any landscape photographer would do.

Talking of close ups, most people don't know or use the DA15 for this but it is brilliant for this! It has short minimum focus distance and the HD version has nice bokeh too.

Just one of the film settings for Game of Thrones, and because of this damn TV programme it is getting too many tourists... 20 tripods queueing up in one place and I'm the only local. :(

It is dark under the tree canopy, hence why they used this location. 0.8sec at f11 during daytime but may have had a polariser on!

The DA15 on FF has hard vignetting all around the frame so a 1:1 just removing both sides with full FF does not work. Therefore to get 1:1 you need to remove the top and bottom bits too, it doesn't expand much more than native APSC at the sides, more play in the height.

Thd DA15 only has weak corners open wide or if you haven't learned how to focus it properly. Other mistakes are blaming the lens for not having enough depth of field which is easy done with UWA. It does have field curvature, again you need to know this and forget about brick wall photographs.

It is my mistake if I get weak corners using DA15, not the lens so don't blame your equipment. :-)

Amazing photo and little bird!

You did the right thing... Get the shot and don't worry about the ISO, the latest Pentax bodies have amazing ISO performance anyhow.

The K-70, KP and K1-ii have an accelerator chip installed with the sensor to boost ISO performance and it works fabulously. :)

The IQ from that 50-135 is great.
