Hello guys, I am new to dslr and these photography stuffs. I just bought Nikon D5600 camera(Used Pentax K10D before). I have a Sigma 70-300mm Apo DG lens, and I tried to mount it on d5600 but it won't mount.I am afraid to force mount it. How do I know if the Sigma lens is compatible to d5600?I read some reviews and I found out that sigma 70-300 and nikon d5600 is compatible. Thank you :D

I'want to to buy an old (in technology years) Pentax DSLR to use my old M42 50mm Super Takumar (it's from a Spotmatic, the very first camera I ever had). I only need one dial to control the shutter speed, as I'll control the aperture right from the lens. I was thinking something along the lines of the "old cheap reliable workhorse", maybe a Kr or Kx. Is there any limitation regardless metering, or something? I already have a high end Pentax, but I want the "new-old one" to be attached to the...
I got an old set of manual extension tubes and wanted to give them a try in combination with my Samyang 85/1.4 - which is a great lens, but can only focus down to 1 m. Wanted to have a look at its hidden macro capabilities ... :) So I got my manual PK extension tubes out; they have both the aperture control lever (for stopping down the aperture during exposure and for DOF preview) and the aperture simulator - not used on the digital DSLR line. But I had to discover that you can't stop down...
I have just downloaded and installed DCU 5.6.1. I usually develop my RAW photos with Lightroom, but from time to time I also use DCU. To my surprise, it seems that Ricoh-Pentax has apparently dropped PEF support, as I cannot open PEF files from my former *ist DS or K10D with this updated version of their software. Now I use DNG on my K-7 and K-S2 bodies, but even some PEF shots taken with the K-7 cannot be open with DCU 5.6.1 Has Ricoh dropped PEF support intentionally or is it a bug? Or...
Sigma Zoom Master 35-70mm f2.8-4 or here Lately got a chance to buy this lens for small money. Knowing nothing about this old goody I thought I´ll give it a try on my trusty old K10D. Here two samples of what it produces mounted at the K10D : 70mm / f 5.6 Not a superfast and automatic lens, it still looks well built and gives the feeling of old time shooting style, but I wasn´t not looking for an all automatic fast lens. I think for really small money (~ 30,- to 40,- €) one can get...

Hi there, I recently purchased a K-S2 body, and am trying it out with my lens collection. For some reason, my Sigma 50-200 4-5.6 HSM acts weird. It sometimes works, but very often it won't focus, and the indications in the viewfinder go berzerk. The lens works flawlessly on my Samsung GX-10 (Aka Pentax K10d), and all my other lenses work fine on the K-S2 (although the Sigma is the only one with a built-in focus motor) Anyone experienced something similar? Regards, Peter.
I'm new to photography and would like some advice. I have a K10D with the kit lens. I'd like to try shooting bird photos. Is 300mm zoom enough to get usable pictures? Sigma, Tamron and Pentax all have similar lenses in this range but the Pentax is $100 more. Is the picture quality better with the Pentax that justifies the extra cost? Money is a real factor for me so Sigma and Tamron are what I'm leaning towards. Thamks for any input. And I really like reading the forums. Great group.
