Perhaps the better photographers tend to be more dedicated to the art and afford more expensive equipment? Not suggesting it is the equipment, just that the better photographers have the equipment.

Of course that will not always apply, really good photographers will get better photos whatever they use!

The My HD Pentax-DA AF Rear Converter 1.4x AW does not vignette the KA 50mm f1.7 on my Super A, just tried it.
It is full frame on 35mm so will work on the full frame camera, when it arrives. It works with Screw drive and SDM/DC focusing lenses, by passing on the focus signals to the lens from the camera. It can't be used with the following as mechanical damage may occur, but in reality you are unlikely to want to use it with these.
smc/HD Pentax-DA 15mm F4 ED AL Limited
smc/HD Pentax-DA 21mm F3.2 AL Limited
smc Pentax-DA 40mm F2.8 XS
The other Pentax site lists it as full frame compatible, if you don't believe me.

The adapter af f x1.7 covers 35mm full frame but it does not pass through the screw drive focus as it was made as an adapter to allow manual focus lenses to be focused by the adapter.
It does not connect the SDM/DC signals at all so treats these as manual focus lenses.
When using it, you get the manual focus somewhere close and then the adapter focuses the lens correctly.

Since I got it, I find the DA 16-85 is mounted on the camera a lot. The range is very useful and the quality is very good. It is bigger and heavier than the 18-135. On the whole I find the extra 2mm at the wide end to be useful and the lack of reach less of a problem than I thought I would on the 16-85. The image quality on the 16-85 is definitely better than the 18-135.

I also have the 18-135 which is smaller, lighter and has a bit more on the long end. Where the 18-135 scores is when I will be carrying the camera all day in the mountains. It offers a compact lens with greater reach and still works well when there is plenty of light. Whilst test charts show it is not the best lens, it does have qualities that produce really good landscape pictures. The sharpest lens will not always produce the best pictures after all!

So you pays your money and you takes you choice. I'm just glad I have both!

Lensbaby arrived in fine condition.

Thanks Paul for an easy transaction.

No problem, thanks.

Pm sent.

Same for me on my K10, Q and K5. Saved a fortune.

As already pointed out, is 100mm really your best focal length?

The DA70 is a wonderful lens for portraits and anything else. Bit cheaper than the fa77(some might say better as well).
There are also all the 50mm lenses as well. Fast glass at very low prices with the manual focus lenses. Use a 1.4 or 2x converter and you can have 2 focal length's, from a lens. With the 50 being fast the light loss through the converter is not too much of an issue.

photos would also be useful.

I think most has been said already but it is a personal choice thing.

I used to do a lot of photography in the past. Started with an instamatic, even did my own processing and printing. I had to wait for some time to be able to afford a DSLR but once I could it reawakened my interest in photography. I now use the digital most of the time but also use film sometimes. I have not managed to really get into Photoshop and all the computer manipulation software, happy to try and capture the image I want rather than sit at the computer for hours. Not that I want to knock anyone who has those skills or their image's, there are some truly stunning images shown on here!

I understand the slowing down idea but you can do that with digital, if you want. My film explorations now include a 5x4 camera so I get to really slow down! Using camera movements is fascinating and is still manipulating the image, I just get to see the manipulations before the image is captured on the film.

Film is expensive but I like to use it some of the time. Digital offers a different way of doing things and is now very accessible. Both are enjoyable and are worth having a go at, if you feel inclined.
