Reversing the lens works should work okay. My only concern would be f/stop control. A set of extension tubes will give you more flexibility and f/stop control.
Can't I control the f/stop via the ring on the lens if it is reversed?

I'm planning a trip into the Rockies and I don't want to carry the weight of my 105mm macro lens in my backpack.
My question is what is my best bet for a close up rig: a reverse mounted 50mm 1.8D, or that same lens on extension tubes, or, I guess, that lens reverse mounted on extension tubes. I'll be carrying a D810 and a tripod. I'm not interested in "true" macro (1:1 or closer), just wildflower "portraits".
I'm guessing the issues are convenience and image quality, but I've never really used either approach, so I can believe there are other issues to consider as well.

If you are up for hiking, you might go a bit SE to the Wind River Range. No roads to speak of, but the trails tend to be relatively empty, compared to the big parks, and the scenery is still pretty spectacular.

I've been advised to use Live View and Mirror Up to engage the electronic front curtain on my Nikon D810 when shooting closeups or macro. I was told that Live View would help me manually place the focus just where I want it, and the electronic shutter would reduce vibrations.
Then, somebody else advised to the contrary, saying that live view eats up a lot of battery, and keeping it in live view can cause the sensor to overheat, adding noise or damaging the sensor.
Anybody know anything about this?

I will be traveling to DC soon. I hope to be able to explore the Mall inside and out and noticed that many of the museums were a bit vague about what kind of equipment bags they allowed inside. I like to "load up" and go out for the day. The Smithsonian's website says that "small" backpacks are allowed, but that's not much help. Has anyone had experience with this? Would a sling type shoulder bag be a better bet? I would appreciate any recommendations.
I routinely visit Smithsonian museums with a modest daypack (Kelty Glacier) that's about 20 inches tall, 14 inches wide, & 10 inches deep. It often carries the camera, two to three lenses, lens cleaning stuff etc., and a lightweight tripod. They always check inside the bag upon entry, but have never objected to my carrying it around in the museums. As others have noted, no monopods or tripods can be used inside the museums, but I believe you can use them in the sculpture gardens and other gardens, and generally on the Mall.

What FX wide angle lenses do you currently favor in addition to the 14-24 mm? I am getting ready to upgrade to the Nikon D750. I love the rating of the 14-24 but it won't accept filters, it is a bit heavy and is at the high end cost wise. I have used the search option and have read previous posts. (I am very happy with the Tokina as a DX option.) I don't have a limit on my budget because I would rather start with what is the best option and decide from there.
I'm wondering why no one has suggested the 18-35mm 3.5-4.5G ED? Its lightweight, the cost is reasonable, and DxOMark rates it very highly.

I had read so much about the flimsiness of the Nikon's RT-1 tripod mount for this lens, which they charged so much for, that I ordered instead a "DSLRKIT" for the lens from Amazon for the princely sum of $25.99. It took a while to get here from China, and it weighs 4.5 oz or more, but its solid as a rock and I'm happy as a clam with it.

Alas, yes, we love long hot showers, and the ventilation is moderate, so that drips on the mirrors are routine, and drips on the walls are not unheard of.

My wife likes my images, and wants one for her new bathroom design. Anyone know how to mount an image for very high humidity and wildly varying temperature and light levels?

I use an AF Micro Nikkor 105mm 1:2.8 D. I use it a great deal, and I love it.

A friend presented me with this old camera, wondering what it was worth. I'm asking you all the same question.

For many years, I used a set of extension tubes - Nikon K tubes - with a "Blowup Lens" (85mm 1.8). That rig could get me to 1:1, but I rarely used it at that extreme. I got very good chromes; indeed, some of my favorite images came that way. True, you lose light sometime a lot - but if you're shooting verrry closeup, you're probably well-advised to be on a solid tripod anyway. And, you'll lose a lot of light with a macro lens as well when you extend to very closeup. On the other hand, in bright daylight, with modern DSLRs giving good quality up to ISO 1000 and beyond, handheld closeups - not 1:1 - are quite doable.

The effect of this can be seen in Nikon's change of marketing with macro lenses. Up through the Ai-S version of their 105mm macro lens this and other macro lenses only focused to 1:2 magnification, and Nikon sold a matching extension tube to get to 1:1. When that lens was replaced with an AF lens in 1990 there was no associated extension tube, because the lens was an Internal Focus design. It did go to 1:1 without help too.
Just a nit-picking fact check: I have an AF Micro Nikkor 105mm 1:2.8 D that goes to 1:1, and it is not IF; not sure when they went to IF, but it was after this D version.

Does anyone remember box cameras, 116 verichrome pan film, MQ developer, tray processing, and contact prints? I'm 87 years old now and started out with the above when I was twelve. It has been a great hobby.
Sure: my first camera was a Brownie Hawkeye. For my first roll of film in the darkroom, I developed the protective paper backing and left the film itself on the darkroom (i.e., closet under the basement steps) floor! :oops:
