First budget Nikon with Full HD: D3100 diagnostics

Nikon D3100 (2010) was a real technological breakthrough in the budget segment: the first entry-level Nikon DSLR with Full HD video recording with phase detection autofocus when shooting video. The 14.2-megapixel sensor and excellent picture at an affordable price made the D3100 an absolute bestseller. Millions of aspiring photographers and videographers bought it. Accordingly, on the secondary market there is a huge selection of used D3100s of various conditions.

Beginning photographers shoot differently than professionals: a lot, experimenting with settings, not sparing the shutter button. Early YouTube videographers filmed for hours, taking thousands of stills along the way. More than 13 years in circulation - all this is history that cannot be restored without a shutter counter.

Budget resource 100,000 and age

The D3100 shutter is designed for 100,000 guaranteed operations. With careful use it lasts longer. The optimal mileage when purchasing is up to 30 thousand. Over 70 thousand - an estimate is needed taking into account the total age of the camera.
