Do you NEED to buy expensive lenses? .... A comparison.
Interesting! Many years ago I put the DA*300mm on a *ist (film camera) to see what it would do. The results looked OK and, of course, no hidden tweaking by the camera. Have you really been fair to the DA*300mm, though, as far as focusing is concerned? Surely it would have been a fairer comparison...

Do you NEED to buy expensive lenses? .... A comparison.
Nice one Steve. I gave up on Photoshop, Lightroom and Affinity et al as being too complicated for my limited brain to understand (genuine comment, not sarcasm!). I'm left with simple but usually effective Topaz and Faststone. I similarly can't comprehend the fuss over RAW except that it's demanded ...

Schneider Kreutznach Xenar 3.5cm conversion.
I came across an old, folding Balda camera that was, to say the best, clapped out. The shutter was jammed and the back refused to stay shut. The glass was good and once cleaned, it sparkled and despite being jammed, the shutter had jammed open! The iris assembly was working perfectly from f3.5 - f3...

Ah. Sorry about that - I said I'd report back. I've just put it onto a K5 and I will have a play with it tomorrow!

Schneider Kreutznach Xenar 3.5cm conversion.
Here is the lens porn of the Xenar 75mm (I erroneously mentioned 35mm above) mounted, via an M42 thread and a new Chinese helicoid onto my K5. It will cover full frame too, as shown above but the K5 was convenient. The front cell will handle focusing by itself but the addition of the helicoid ...

Schneider Kreutznach Xenar 3.5cm conversion.
Err. No. It is screwed on tight and It takes a little bit of lathe work - fortunately, not on the lens components, although that wouldn't be the first time since all of these beasties are unique and you only have so much space to play with - about 48mm. Neither will any donor lens of less than 50mm ...

I think you will find a problem with 50mm. You simply can't mount it sufficiently close to the sensor. You MIGHT get it to focus as a dedicated macro lens?

What to do with "older" lenses?
Hello, after not being very active for over a decade, i'm back in the "game". I realize there are new lenses, but also that due to the lower demand for DA lenses, some of them have gone down in price substantially (the 16-50mm f2.8?!). With that it means my lenses have taken a massive hit, to the po...

What to do with "older" lenses?
Keep them, unless you don't have the space or really need the money you would get from selling them. You might not use them now, but one day your kids will grow up and leave home, or they will decide that being photographed by you is totally unbearable, so you will develop new photographic interests...

What to do with "older" lenses?
I would add a vote for the Sigma 10-20. I had one for a long while and only sold it when I got a Sigma 8-16. Both big and bulky but a god send when I couldn't use foot-zoom to get back to frame the picture I wanted. Not lenses to carry all day every day but invaluable in circumstances when you kno...

What to do with "older" lenses?
You speak of 'planning a trip' as if the experience will be dominated by which lenses you select. It is doomed to failure! The only lens you need is the A series 2.8/50mm macro and, if you are desperate, an F series 1,7X Auto Focus adapter to go with it. The only time you will need more is for highl...

55mm 1.4 SDM failure --> use with MF or send back? help
hello, i've just acquired a DA* 55mm, it arrived yesterday. The seller said he bought it new and used it twice, but hasn't used it for the past 2 years. Now it arrived and the autofocus doesn't work. Known problem. The price was very good, but still it was supposed to work. The seller is offerin...

55mm 1.4 SDM failure --> use with MF or send back? help
Keeping up with kids usuing manual focus is tough so I would return it. Whether or not the AF on a fully-functional DA* 55mm is good enough to keep up with kids is another matter - I've heard AF is slow but have never tried it. Given that the AF on a working one is likely to fail before long, is g...

55mm 1.4 SDM failure --> use with MF or send back? help
thanks, yes i tend towards that, i have to say the bokeh is pretty impressive, sometimes the colours are also very good (i've been shooting with light coming from different directions inside the flat, very different results), but i also have a 55mm 1.8 K which is also very good. The plan was indeed ...

55mm 1.4 SDM failure --> use with MF or send back? help
It depends on the discount. It's a great lens when working correctly. I actually wouldn't mind purchasing it from you in order to attempt an AF fix. PM sent!

55mm 1.4 SDM failure --> use with MF or send back? help
Are you using it on full frame or APSC. A Sigm 30/1.4 on APSC might be another alternative.

55mm 1.4 SDM failure --> use with MF or send back? help
i am using it on a KP so APSC. I have a FA 50mm F1.7 and would like a faster / nice bokeh portrait lens, not that the 50mm is bad, but i find 55mm to be more portrait like somehow.
