Neewer remote doesn't close the shutter

I've been looking for an answer to this but I can't seem to find much info.

A little while back I picked up a Neewer EZz-C1 through some deal on Amazon or something. Well, I finally had a chance to mess with it and I'm running into an issue. Connected to my K3-II, it seems to be setup correctly and when I initiate the timer it does the delay and then begins the exposure by opening the shutter. However, when that timer runs out, the shutter never closes. I can use the manual shutter button to close the shutter just fine.

I have reached out to Neewer but figured I'd throw up a post here to see if anyone has had an issue like this of if anyone has this same remote and can verify that it does indeed work as it should on the K3-II. Maybe there is a Bulb setting that I'm missing?

Thanks

Edit: Yep, it was a setting for Bulb. I had it on Setting 2 which requires a press of the shutter at the start and stop of an exposure. Switching to Setting 1 fixed the issue. As soon as I typed the end of the post above I had a feeling I knew what it was.

Well, please disregard and delete if necessary. Or, maybe this will help someone in the future.

Thanks. I love shooting birds in flight as it just adds so much to the image. Sadly, as much as I love my K3-II, the autofocus still leaves me with so many missed shots. Holding out hope for a new body...someday...

Eagles are from Valdez Alaska. I was up there in July as one of the first salmon runs was arriving. Eagles were everywhere. I even got lucky and had a day of bright sunshine which really made it fun to shoot.

I have been to Squaw Creek. Of course, now it's called Loess Bluffs NWR because "squaw" was deemed offensive. However, the creek is still called Squaw Creek. Don't get me started on the silliness of some things.

Speaking of, here's a couple from last fall when the snow geese were staged up. For those that haven't ever seen snow geese in huge numbers, it's absolutely amazing.

Here's a link to a crappy video of thousands of birds taking off

Yep, it took 7 shots or so to get the whole formation and the milky way in the shot. Below is a photo I happened to take that night of the back of the camera so you can see how much I was capturing in each image. It's a horrible, blurry example but hopefully it illustrates enough. Basically, I was a lot closer to the rock formation than the final image appears.

At the time of my trip, I wasn't 100% sure on the rules about light painting so I didn't have lights setup for it. However there was another couple that was hanging out and they had this lantern thing so I used it to my advantage :)




Actually, here's a photo from my phone from the location I was shooting from just to give some perspective.

Yes they are. I've been lucky enough to be in some places where there were numerous hummingbirds so I could stand back a little and get some good light. Still tough but eventually you get some decent shots.

This was with the DA* 300mm at about 20 feet or so. A gimble mount on my tripod is a godsend in situations like this.

Samyang 24mm f1.4 "Softness" concerns...Input please
Posted By colonel00
Replies: 20

Yes, I already have a 14mm f2.8. I was looking for something faster which is why I was trying this lens out. I've used astrotracer, did 4 minute exposures the other night in fact, but there is still something nice about the simplicity and authenticity of capturing an image without all of the stacking and blending and all that. There is also the time factor where in an ideal situation, you have the time to set up and take long exposures and multiple images but that isn't always the case.

I think understand what you are saying about light gathering. Maybe it's just coincidence on these two lenses but it mirrors pretty closely the ratio between at the "rule of 500" where it's a 13.8s and 23.8s exposure before the stars noticeably trail. Anyway, it's made me investigate and learn a little more today.

I've read the reviews about softness wide open. I just posted this thread to ask if what I was seeing was typical or not. As we know, quality control with the Samyang/Rokinon lenses can be a little dodgy so I was just hoping that others had use the lens for astro stuff and could confirm the same results or tell me that their copy did better. If my results are on par with findings from "accepted" lenses then so be it. But, as Clackers chimed in, his 24 was always sharp so it makes me question.

I also read this review which shows some 100% crops that don't exhibit the same weird bubble things (is there a name for this?) but then again, photos were taken on a Sony a7S.

Sorry, now you've lost me. How does a 24mm at f3.5 gather more light that a 14mm at f2.8? f3.5 is 2/3rds of a stop slower that f2.8. On top of that, a 24mm lens only allows for roughly a 13s exposure before star trailing versus 20s-25s (23s really) on the 14mm.

Interesting. I'm not discounting the capabilities of the lens but I have a hard time seeing an f3.5 as an astro lens. Sure, with some "help" like astrotracer or a tracking mount, any lens can be fantastic. Hell, I was doing 4 minute exposures at ISO100 the other night just to try things out. However, that just cause more work too. I'm no Photoshop pro so stitching photos together from multiple samples just complicates things a bit.

I will disagree that a f1.4 label is important in the simple respect that sometimes you just need to gather more light in a limited amount of time. I'm perfectly happy with the 14mm f2.8 but it just struggles at times with a 20s exposure to avoid star trails but still capture enough light. Maybe my hopes were too high that the 24mm could exceed those results but that's all part of the game isnt' it? If it was easy, everybody would have their cellphones out taking fantastic astrophotos.

Funny side story, when I was at Yosemite, waiting for the sun to rise, a very nice "kid" (easily in his 20's) came up to me and wanted me to take his photo with an ipad. In the pre-dawn light, with is back to the breaking dawn, it was about impossible to get any image at all. However, it struck me that it wasn't that long ago that cellphone cameras were mostly a joke for anything where nowadays, they could honestly do a pretty damn fine job of capturing images (unless you are printing large(ish).

Yeah, it's about 3-4 hours away. The forecast was good for last night and a good moon for a dark sky so I drove up and pulled an all nighter. Sadly, even Yosemite isn't the darkest of skies depending on the direction you face but it's still loads better than most other places around here (Bay area).

It's funny you mention it because my 14mm is actually dead on at infinity at the stop. I got lucky apparently with that one.

I'm still torn on this lens after going through a bunch of the photos. Even once I was able to make some tweaks to the focus, it's still producing some bubble distortion things and some aberration (fixable) but you really aren't going to see that unless you are really peeping at full crop.

f1.4 13s ISO1600

Thanks again. No filters and the elements were clean Na Horuk.

nocturnal, It's not necessarily for online sharing. I can't remember the last time I was on Facebook. However, I do share images with folks from time to time. I would to have prints at some point as well. What size do you think would still be acceptable?

I spent last night (all night) in the dark skies at Yosemite and have some 2400 photos go to through. Lots of timelapses obviously. On the bright side, I think I was able to some more positive results but I'm waiting to see how it comes out after PP. I found that when checking focus in live view, if I tweaked the focus ever so slightly, the purple aberration would go away it seemed to help. I'll post up some examples once finished.

Nope, no filters. Also, I should mention that this is on a K-3 II.

Yeah, I think that's what I'm trying to get to. Maybe I'm expecting more from f1.4 than this lens can deliver. If it's just a limitation of the lens that there's nothing that can be done and I'll stick with my 14mm f2.8. However, I was really hoping that some others that have this lens and especially use it for astro stuff can chime in with their experiences and examples. I'm actually heading out the door to go to Yosemite so we'll see how this does in the real world.

Here are some more quick tests. All RAW images straight out of the camera with only cropping done.

Here is a close focus test. It was too windy outside to get really good light so I had to do this indoors. This was pretty close to the minimum focus distance.

Thanks for the reply.

a) I checked the focus and the infinity mark is pretty much dead on. I'll get some other example shots uploaded here soon.
b)I can understand a little softness at f1.4 but if it's this bad then what's the point of having that option aside from doing some artsy portraits? I don't have to stop down my 14mm as it is sharp wide open at f2.8.
c)Yeah, I'll check for decentering more. However, in the example photos above, the issue was consistent across the frame


Also, 24mm was entered as the focal length. All shots were with 2 second timer.

I tried looking through Flickr. The main problem is this lens for most cameras doesn't register the aperture so the info isn't in the EXIF data.

I'll take some more example photos and post there here in a second.

Nope, not too late. Brick wall test is coming up soon.

Though, I've always done the brick wall test for decentering, not so much for aperture softness.

The issue here isn't decentering but what is acceptable "softness" wide open for this lens. It's not just long distance stars that show this issue. I can take some shots from across the room and f1.4 is really quite blurry in fine details at a full crop but it's better at f2.8. I'll take a few photos here and post them.

Also, I forgot to mention that the cropped shots above are from close to the center of the image. If you look closely, you can match the star pattern of the crops to the full sized image just up and to the left.

Just looking for some input from folks that have owned/used the Samyang/Rokinon 24mm f1.4. I recently picked up this lens, mostly for nightscapes/astrophotography but this copy has me a little concerned. I've read a bit that it could be a little soft wide open but some quick, preliminary shots seem to be worse than I expected. I will get some more examples tomorrow but this is what I see with just a few quick shots of stars. f1.4 looks really, really soft to the point of out of focus. Stopping down obviously gets better but if I have to go to f2.8 to get decent result, that kinda negates the usefulness of this lens as I have a 14mm f2.8 that has been great for me. I just wanted something faster.

I guess I'm just looking for opinions on whether this is just the limitation of the lens or if it's a bad copy.

In the examples below cropped pretty much 1:1, f1.4 and even f2.0 to a point seem way too soft and blurry. The little halo/bubble thing that is formed just adds to the mess. These were shot at 13s so there is a little star trailing which I'm fine with on a non-cropped image.

Edit: I should also note that nothing was changed between these shots aside from aperture. Focus seems to be pretty good and on the infinity mark.

These aren't fantastic images by any means and there is a lot of light pollution around here. I just wanted to get a quick test after getting the lens.

Examples (untouched aside from cropping):

f1.4



f2.0



f2.8



---------- Post added 05-20-17 at 02:35 AM ----------

Here are the full images so you can get some context of the effect of the issue. I used Lightroom's Auto white balance adjust these. It's not as noticeable but still not something that I'm happy with I don't think.

f1.4- Not horrible from afar but still "fuzzy" and just not quite right.



f2.0 - Better, almost tolerable but not there yet.



f2.8 - I can accept this but again, this voids the speed of the f1.4 lens.

Thanks. I actually have some memory on order that should give me 32gb and I'll look into setting up a RAM drive. I'll see what improvements it makes and if it still struggles, this machine can become a backup machine for redundant storage and I'll look at diving into a new machine build.

Thanks for all of the replies. I currently have an AMD a10-7850K APU processor running integrated video off the motherboard. I can't remember what the motherboard is off hand. Currently I have 8GB of DDR3 1600 I think. I have three SSD's, one for my OS (Windows 10) and two that I copy files to for editing before I eventually move them to a regular HDD for long term storage. I know I may be "wasting" write cycles on the SSD's by doing this but it has helped with speed. However, the system still struggles even with simple things like edits. For instance, if I use the brush tool to touch something up, I usually have to wait a second or two for the effect to happen and then go from there. It's not fluid at all. Switching between photos has a bunch of lag, especially if I am switching while at 100% crop. I get by alright but on days when I'm shooting birds and I come home with 500 images to go through, it really gets old having to wait on each image to load slowly.

Now, I have considered just getting some more RAM and possibly a GPU and hoping that would fix the problems but that still leaves me with a moderate investment on a machine that is still fairly long in the tooth.

I'd love to hear some input on system specs, parts lists or even prebuilt machines I should look at for a new PC. It will mainly be used for everyday stuff like surfing the internet, work crap and all that along with PP of photos and videos. I don't need a gaming rig but I'd like something pretty snappy. Currently my machine bogs down with Lightroom and there is a delay when edits are applied and much worse at times when going from one photo to the next.

Anyway, with a budget of $1K or under, I'm hoping for some suggestions from some of the techies and possibly some good deals to watch for.

Thanks.

Which lenses? To me this just seems to be a bit odd. Granted, I'm not thinking that it would cause issues with starbursts with the 300mm :) but it still should be this off should it?
