lens compatability with full frame
[quote:3496ace15f="BruceStrachan"]INot sure if my DA 100 mm f2.8 macro (the metal good one)is or isnt. There isn't a DA 100 macro lens - the non-WR and WR 100 mm f2.8 variants are D-FA - fully compatible I am sure with 35mm Good news... What abut the 16-85 is that a definite no?[/quote] Yes, the...

lens compatability with full frame
It would be OK, it is a friends lens that I borrowed. He won't mind. In seriousness I would not mess about with a lens either. Just wondering if it would make a difference to the sensor area covered by the lens. I'm sure some brave/foolish person will give it a go sooner or later.

lens compatability with full frame
Woah there Bruce. Love the kit you're with. I think releasing a good quality lens dedicated to APS-C shows commitment to that format which many will see as a good sign, far from a kick in the teeth. All camera makes offer great cameras that are capable of producing stunning images. I have...

lens compatability with full frame
I can't believe they released such an expensive lens when full frame was coming and didn't make it forward compatible. ... I can as no one can make a 16-85mm that is FF compatible. It's just not physically possible. Besides: the 16-85mm is a very good crop sensor lens that is worth its purchase pric...

18-250mm lens. Is this good please?
If the lens you have seen is the latest version of the Sigma 18-250mm then this is the same one that I got just over 2 years ago. I chose it because it got better reviews than the Pentax 18-270 and was much cheaper ! Is is a FANTASTIC lens and I used very little else on my K-r during 2014 coveri...

Primes or zooms?
Depends on the prime and the purpose. I reckon a portrait session with, say, a c.70mm Pentax lens would be very rewarding. Or an afternoon taking macro shots with a Tamron 90mm. Not that I own either. In truth I find most prime lenses a bit restricting on a crop sensor camera. 28mm is just about...

Primes or zooms?
My aim is to use the camera and it's controls in order to take advantage of the maximum the sensor can muster for each situation .... I see the essential 'capture point' decisions as follows ; Focal Length Framing and composition Focus accuracy Aperture choice Exposure time (as needed for ste...

150-450mm vs DA*300mm
Hi, I own the superb 300 F4 and the 1.4x tele adapter. I find them excellent for photographing small wildlife (the K3 sensor allows further cropping) and they fit easily in my small Tamrac shoulder bag. I can understand the need for a zoom for say big game as i gather you are often closer than expe...

150-450mm vs DA*300mm
Thanks John, not really what I wanted to hear but probably what I expected! As I have been using it on a K50, and on occasion got sharp shots, it will be interesting to see what happens with a K-1. I expect the sensor will be a real test for a lens.

43mm Ltd jammed.
Another thumbs up for Alan Marlow, he made a nice job of cleaning my Bigma.

Wondering what the field of view of the DA lenses is on the K-1?
Are these with the K1 in full frame mode or using the cropped sensor mode?

Wondering what the field of view of the DA lenses is on the K-1?
An interesting one this: Samsung 10-17mm@14mm (Samsung's variant of the Pentax version.) The field of view is quite useable from 14-17mm and comparable to using the lens on APSC, The walls on either side are at 90 degrees so FOV is wider than that. Zooming out to 10mm makes the image smaller (t...

Wondering what the field of view of the DA lenses is on the K-1?
Will you be posting photos made with DA lenses in K1 crop mode? Thanks for your comments John. In K-1's crop mode they must surely be very similar to taking them on a K-5, K3 etc. All the full frame mode does on the K-1 is to force the camera to store the image from the whole sensor, saving the ed...

Some real world images from the K-1 with DA lenses. All show the full frame out of camera jpeg downsized to 1000 pixels in Photoshop Elements for the forum. I'll start with some truly budget lenses that many will already own. DA 35mm f2.4 @ f7.1 (The plastic fantastic) As far as I can see i...

Wondering what the field of view of the DA lenses is on the K-1?
That's an interesting report, thanks. I think in resolution/clarity terms we were expecting performance similar to the latest K5 models, in cropped mode. What would be fascinating to know is whether the K1 sensor offers any dynamic range advantages over the K5 at similar sized output .....

New lens time
I have it in Canon mount but I only use EOS film cameras as they don't suffer from poor dynamic range like their digital Canon cousins :) It's certainly enjoyable to use and feel good in the hand. I haven't seen any scans back from it yet anyway as I got it quite recently, though I did have a br...
