I have been recently having a lot of issues when shooting timelapses with my Sony A7Rii. In today's test I was using a Neewer intervalometer and my camera is set to Manual: all settings are set to manual (aperture, focus, iso, shutter speed). I then let the intervalometer shoot pictures at a 5 second interval. The lighting in the room hasn't changed at all and given that the camera settings were all set manually I should have received a series of very similarly looking images. If I am not missing something then nothing should have caused any changes in exposure in the images, yet the result is that randomly some of the images were dramatically underexposed, even though the settings according to the exif data are identical. I've attached a screenshot of the exposure line of all images in the series. The blue line should have been a smooth and almost straight line given that the settings were identical and the lighting in the room hasn't changed. I've also attached a screenshot of a part of the series from Bridge, showing that some of the images are randomly underexposed. And here is a link to two sequential RAW files out of the series (the files are currently still uploading to Dropbox). They show identical exif settings yet one is strongly underexposed (the images before and after were normally exposed again). Does anyone have an idea what could be wrong with my camera or settings? Much appreciated, Jan

Hi! I've given up. It's hopeless trying to Google my way out of this pickle. Every time I mention "bulb" the search just shows websites instructing you on how to turn it ON. And trust me, I've looked and tried to retrace my steps. I was out hiking last week. During this time I took a lat of photos and let the A6000 hang around my neck, as well as packed in a relatively big fanny pack. When I got home I realized that a bunch of the last photos I took were all smeared. That's when I notice the shutter speed expressed as 30" instead of the regular 1/600. I'm not all that technical when it boils down to hardcore camera science, but I love taking photos during these kind of adventures. And I love my camera. That's why I'm now reaching out to you guys. What's the problem? How do I "get back" to the regular display of shutter speed? In short, how the F do I switch of bulb mode? I recorded a short vid on my phone to demonstrate. It's not at all very detailed or thorough, but I hope it's enough. Thank you!

TL;DR: got any recommendations for a cheap fast manual non-radioactive 50mm prime? I have an a6500 with the 16-70mm kit lens and also the 30mm f1.4 Sigma lens, which I love by the way. However, I want to use some legacy primes to experiment with different focal lengths, perhaps a tilt adapter later on, etc. I also don't want to use a radioactive lens, because firstly I don't have a basement in my small apartment to "hide" the lens away when I'm not using it, secondly, I have a dog, thirdly I just don't want to take the risk. I have shortlisted it to the following: Minolta rokkor-md 50mm 1.4 - might be radioactive?? but f1.4 is very fast and apparently it's sharp too Helios 44m 58mm f2 - this is a lens primed for its swirly bokeh but I've heard on crop sensor bodies the bokeh doesn't swirl as well Auto-Takumar 55mm f2 - this has great "soap-bubble" bokeh, and works well on crop mode. The only thing holding me back from pulling the trigger on this lens is that it may be radioactive (according to the Angry Photographer it's not but others say it is, and Pentax was notorious for radioactive lenses in that era) and also it's very RARE and fairly expensive. I'm in love with the look of the Takumar lenses, by the way. Konica 50mm Hexanon f1.7 - this lens is very sharp wide open and very inexpensive, don't think it's radioactive (is the bokeh any good?) Nikon 50mm f/1.8 AF/AFD - not that vintage but fairly cheap and certified non radioactive (lens-makers stopped using thorium in the mid-80's) Anyone got any suggestions/tested the radioactivity of these lenses? Also, does the radioactivity vary from lens to lens? Thanks.

Just received an a 7Riii and am learning the menus etc. But it would be helpful to have a book to read, make notes and use as a reference. I can find books on the a 7Rii but not the a7Riii. Anyone know of a book on the a 7riii?

Long story short I only need 1 lens to work and function a certain way. I do NOT need autofocus. But it's the new Sigma 14-24mm for Nikon that just came out a little while ago, not many people have it on their radar. I just need it to work on aperture priority mode and be able to bracket photos as well. But i shoot on manual focus at infinite. I'm wondering if only the more expensive adapters like the commlite will work with this function or if the cheaper 99 dollar ones will let me control aperture as well. I care about image quality but if the more expensive adapters are only that pricey because of autofocus I could care less. Any info would be appreciated, thanks!

First: Lesson # 1 - learn your (my) camera! I own an A6000 and 90% of my shooting is Aperture Priority. When attempting to shoot the Blood Moon last week, I could not focus. First I keep forgeting I recently set BBF - so it ain't focusing until 'I push the button'. However, my post has to do with going manual. After playing in the dark I realized I don't know how to go Manual focus and more. Then I see when searching the web ah ha ... there is Focus Peaking. If a member can be so kind to suggest a link or links to understand manual and when it serves best - please share. If a member has a series of steps they use to go manaul - please share. Thanks

(MODERATORS: I noticed the legacy lens part of the forum too late, if you think this should go there, by all means, move it. It probably does fit there best.) I worked as a professional sports photographer for years, blindly shooting away with a Canon and not truly appreciating photography. I got a promotion and was no longer required to shoot, so I sold my gear. After a few years I got the itch again, but there were stipulations: No. 1 — No backaches. I wanted to go light. No. 2 — I wanted to shoot on a budget (I've added kids and other expenses). No. 3 — I wanted to have fun. I did some research and talked to a photo buddy, PMR (some Sony shooters probably know him), and I settled on an a6000. Picked one up with a kit lens and ordered an adapter for some old FD stuff I had sitting around from back in the day. And there's where my trouble started. After messing around with the old standard Canon FD 50mm 1.8, I went immediately to Amazon and bought adapters for every mainstream mount — the best-rated, yet cheap, adapters. Fast forward two months, and I've spent about $250 at various thrift stores, garage sales and pawn shops picking up a vast array of manual focus lenses and other finds, and I'm having the time of my life. So far, here's what I've got: Nikon F mount lenses Nikkor-S.C. Auto 55mm 1.2 (with an old Nikkormat EL body thrown in) Nikkor 135mm 2.8 (with a Nikon FG body added to the deal) Carl Zeiss Jena 28mm 2.8 Sigma AF 24-70mm 2.8 DG (auto-focus doesn't work, but it's otherwise mint) Sigma AF 15mm 2.8 fisheye (again, no-go on autofocus, but manual focusing is smooth) Auto Vivitar 200mm 3.5 (stuck wide-open, unfortunately) RMC Tokina 400mm 5.6 Minolta MD mount lenses Minolta MD Rokkor-X 45mm 2.0 Minolta MD Rokkor-X 50mm 1.4 (threw in a Minolta XD-11 body) Minolta 1:1 extension tube (I believe this was made for the 50mm 3.5 macro) Canon FD mount lenses Canon FD 50mm 1.8 (two copies, both flawless) Canon FD 28mm 2.8 S.C. Tou/Five Star MC Auto Macro 28mm 2.8 (surprisingly good little lens) MC Super Albinar Auto 135mm 2.8 MC Auto Zoom CPC CCT 75-200mm macro 4.5 Osawa MC 70-180 macro 4.5 M42 mount Auto Mamiya/Sekor SX 135mm 2.8 Pentax K-mount SMC Pentax-M 50mm 1.7 SMC Pentax-A 50mm 1.7 (got these guys for $2 each, mint, with caps) A word of warning: This can get out of control. But I'm not sure I'd have it any other way.

I am getting mine delivered today. I will be sharing my photos, taken with Sony A7r. Let’s see yours. (If a similar thread exists, please let me know. I did not see one.)
