By M NugentCan anyone tell me what is used to secure the model dial on a A7R2?. Mine will not stay attached and falls off easily. The inside of the wheel appears to have some kind flexible adhesive, but its is slippery or waxy, and doesn't appears to be an adhesive at all. Thank you
I tried astrophotography for the first time this weekend, and have a few questions.
I've read many times that an F4 lens isn't fast enough for astrophotography, but it was my only option this weekend. I think the outcome was far better than I expected, although my "standard" for results probably isn't that high.
Anyway - I tried 30 seconds F4 on approximately 16mm, on a tripod of course. I can see glimpses of the milky way, but not as clearly as the "typical" astro-photo you'd see from an experienced photographer.
Question 1: Which camera settings (shutter speed, aperture, iso) is preferable in order to capture the milky way?
Question 2: Is it not enough with only one photo or are you supposed to stack multiple photos?
Question 3: What is the benefit of stacking photos - will the milky away appear more clearly, or is it to reduce noice?
Feel free to advice me (and other beginners) on how to make the milky way appear more clearly. I'm sure the camera settings should have been different .
I'll throw in a couple of sample images from this weekend. Both are edited in LR.
By cwsStill loving my A7R2.... just finished a surfing trip to Maldives aboard a boat for 10 days... we were parked a fair distance from the surf break and longest lens I had was my FE 4/70-200 G OSS.
While I got some OK shots I could crop into... nothing was close enough.
I borrowed our surf guide's Tamron SP 150-600mm F/5-6.3 Di VC USD G2 A022 with Canon mount and used it on my Metabones EF-E mount....... even at 600mm there was still a lot of wasted real estate in the pixels, and although I used a monopod to carry the weight, it was very hard to stop even tiniest movements on a rocking boat... but still managed to get some magic for my mates when I wasn't surfing.
Original frame reduced to 10% size, and then crop into 1:1 frame to 1800x1200px.
1/800th sec, f11, auto ISO 800, manual focus trying to lock into the distant area for faster shooting (although automatic focus still worked)
Probably should have stayed at at least 1000th sec.
Very happy I got some useable closer shots.... older blokes can still have a lot of fun!
By PHWRaging wild fire in California. The ashes covers large part of sky, and gives a strange hue. Sunset in the distance glows in unusual cherry red. Not a happy day for those who lost their houses 30 miles from where this photo was taken earlier today. Cross my fingers for those brave firefighters.
