I have a neat little WHITE Lumix LX7 that really screams *amateur* *tourist* and shoot through a fast Leica zoom lens that slips past most of those screeners in a coat pocket easily..

You are still in the camera system trap and that's something that grows and grows as if it has a life of it's own. Why not ditch the system idea and think about really lightening the load with the recent Panasonic Lumix LX 100 II. It's Micro Four Thirds sensor with 17 MP (crop factor 2) and has a fixed Leica Summilux 24-75mm (35mm equivalent) f1.7-2.8 Zoom Lens. Weight 392 grams (just less than a pound) all up. Add a couple of the Godox radio sync TTL speed lights a decent tripod or monopod and you're good to go.

I'm going with the other two responders who suggest going to the advanced search of eBay and entering each individual item in the description box then check the box for sold items and click the "search" button. The results are actual sales which are the best indication of real values.

If you are thinking about what kind of camera to buy I suggest you stop and think carefully about making a business of portrait photography. The first thing you need before buying an expensive set of tools is experience in a customer oriented business and a business plan.

If you use a crop sensor Nikon DSLR your best bet for a portrait lens is 50mm Nikkor lens which acts as the equivalent of a 75mm and saves you a bundle of lens money.

I once operated a portrait studio for Expressly Portraits. an upscale chain that used Mamiya RB67s (60mm x 70 mm negatives) and 90mm lens. We delivered the finished portraits up to 11x14 in one hour after the sitting was completed. Few customers wanted more than one or two 11x14s and most preferred more 8x10s and 5x7s plus a handful of wallet sized prints. Very, very few wanted 16x20 or 20x24 which were also sold, just took a week more or less because those were all printed in a central lab which put express mail time into the delivery equation.

Today's crop sensors Nikon digital cameras make perfectly acceptable 11x14s which I'm fairly sure would please a customer assuming your work as a photographer met there expectations.

When I was a kid in the 1930's I spent many hours looking at a huge stereo photo collection in the Baldwin Public Library which had at least a dozen of those viewers in a special alcove devoted entirely to viewing the collection, a small addition to the building to house it, and comfortable furnishings all left to our city in a wealthy resident's last will and testament.

Remember how to get a very large umbrella effect for the shadow fill light by using the corner of two white walls and a white ceiling and aim a wide flash at the point formed by the three surfaces.

Have a strange impression of artificiality on the upside down Scooby Do photo. Almost as if it's put together with library paste. Does anyone else think it strange?

I don't see any blurring, however, my eyes at 86 are getting a bit blurry themselves.

Sounds to me as if the mirror is not getting out of the light path. It's a job for a repair technician on the camera body not the lens.

Just sold my last 35mm rangefinder Kodak Retina (model IIa) as a fully functioning sweet looking user to a younger photographer who is going back to some film work again. When I was a kid in Michigan (late 1930-1945) we too called all cameras Kodaks.

By the way, as an old writer of note once penned, the reports of it's demise are somewhat premature. Among hundreds of current products are some very good ink jet photo printers. Walk in any half decent drug store and you are bound to see the word KODAK somewhere (perhaps in the small battery rack). Kodak is almost everywhere if you are really looking.

Panatomic X was my go to film for many years and your cat photo illustrates perfectly what I truly miss in digital photography. Thanks for the reminder.
