Good point (also without "and-shoot")

Not too bad!

Nice gun, but rather expensive. Almost as expensive as a good used Canon EOSD-1DX

I always carry a small point-and-shoot for my MTB rides in the forests and suburbs here in Sweden. I know, the discussion camera vs. cellphone always comes up. If you just want a good photo in wide-angle and do not give a rat's ass about depth-of-field and background bokeh, the phone is okay.
Still, there is one terrible property of the phone regardless of the picture quality, and that is the handling. The phone is very bad for quick actions and especially bad if you have gloves on. You can handle a point-and-shoot with gloves on. Try that with a phone!
A good point-and-shoot has a zoom too. It is closer to a real DSLR concerning general properties than a phone. Of course, a phone is far better than nothing . . .

I have varying experience of 3rd party batteries. My modern Li-Ion Canon batteries have been okay. However, I have found that the batteries for my Canon EOS-1D Mk II N have not lasted as long as the originals. Those old types of Canon professional cameras have a kind of cell configuration that is a nightmare for designers. They used *TEN* AA Ni-MH cells *in series*! They are almost doomed to a sudden death! If, or rather when, one cell goes slightly bad, the entire voltage balance in the pack is quickly corrupted and an avalanche destruction takes place. The same was valid for early multi-cell power tool battery packs.

I like the dinosaur 1D so I plan to make a pack with Li-Ion cells instead. Of course, it can NOT be charged with the original Ni-Mh charger. I have to build in a BMS in the pack or make the cells easily removable and charge them in the charger that often comes with them. Some battery cells have built-in BMS, but it is still not a walk in the park to charge them without the designated charger. In that case I have to design an own BMS and charger. Too much job.
Assume the following: The 1D runs on 12 V. However, it has to be capable to run on 12 V minus some voltage [when the cells get low charge] so I will try to see if it can run on 3x3.7 V = 11.1 V. Each Li-Ion cell has nominally 3.7 V except on full charge situation. They stay there pretty constantly. If I can squeeze them into an empty battery pack that easily can be opened I have reached the finish line.

B&H has a reputation to sell only good stuff. My overall own experience of B&H is extremely good.

Nice view! What is the tall building to the left? University?

I have Canon EOS series. 1D Mk. II, 5D Mk. III, 6D and 60 D. The 1D has Ni-MH battery packs, the others have Li-Ion. When I am out there doing Street or hunting for funny dogs or cute cats on the prawl, I ALWAYS have the switch in ON position! I have even forgotten to switch it off when back home, but the battery did not die fast.

Talking about batteries, I noticed once that my battery, Li-Ion, died quicker than Fido munched the Sunday steak he stole. It was 10 degs. F outside! I had two freshly charged batteries with me on a car race. The battery died within 15 minutes. I thought that it was defective. I put in my second battery. It died after 15 min. too. I realized that the very low temperature was to blame. I took battery #1, put it in a plastic bag and put the package in my very warm armpit. It sat there in the warm hairy environment for 20 minutes and heated up again. It worked like a charm! I just swapped the two batteries between my armpit and my Canon (I swapped armpit too). They could take all photo shoots the entire day!

I have/had no bone to pick with Nikon. I just mention my experiences. I used EXACTLY the same chemicals, film, enlarger lens, enlarger paper chemicals in both cases. This was an almost one yr long unintended experiment. I know what I saw. My observations are real.

WRONG! It definitely will. Okay, I go back to mid sixties. I was a teenager then. I used two Leica M bodies and three original Leitz lenses. I could make enlargements like 50x60 cm^2 super sharp with a wonderful brilliance and contrast range. I used Ilford film and developer. I had a Leitz Focotar enlarger lens. A very skilled seller talked me into Nikon. I went to the seller with my father and I got two Nikon F bodies and three Nikkor lenses. I started again with my B&W experiments. No brilliance in my prints. I looked for errors in my procedures. I experimented for a rather long time. I found nothing wrong. I went to my father who was somewhat pissed on the salesman. We went there and got two Leica M and three Leitz lenses again. Next roll of Ilford film gave me immediately the brilliance and contrast range I had before my "Nikon Period".

However, I was satisfied with my color slides from the Nikon. The main reason was that the "Photomic" add-on was very good and gave very correct exposure for the critical Ektachrome X. But for B&W, never Nikon again. I found that my friends who had Canon FD lenses got better brilliance than I got with my Nikon. Okay, this was around 55 yrs ago!

Today I use Canon EOS6D, 60D, 1D Mk. II for digital, my (now) old Leica M4, a Hasselblad 500ELM and, a Kiev 60 hand-held, for B&W.

I found some test reports, user reports, with sample photos. NOTE! NO bloody Youtube movies with time consuming yada yada and mumbo jumbo. Here is a link:

This is obviously a cheap, but very portable [slow] telephoto lens. Still is might be interesting to buy it. I have not found (quick look) any test reports of value. Unfortunately, the Youtube movies are pretty much super crap. Like my experience of Youtube in other areas, like car fix. Much mumbo jumbo and yada yada and very little solid information, like I often see on Youtube. I think that I and perhaps some more who is interested in the lens will be grateful if someone finds some real, non-Youtube, test report.

If you do not fly, you do not need a parachute. If you live in a totally different part of the world with a very much stable and safe society, you do not need a gun. A gun can also PUT you in a bad situation. If the bad guy KNOWS that you have no gun, the risk is far lower that he will use it. It will be far worse for him in court if he does. I think that most of the people here know very little about the Northern European societies. If you have USA as a reference only, I can agree to some point. Depends where in the US you live. I spent a few yrs in Morgantown, WV. That place felt very safe. I had no gun. University people usually do not carry guns, even if they own guns.

Periscope! That explains the space for a longer lens. Thanks!
