Imam priliku zamijeniti svoj EOS M za neki od navedenih kamera. 550d je najbliži EOS M(650D) Ali vidim i odlicne slike sa 350D i 40D. Ali 350D nije fully suprotan u BackyardEOS, nema live view, a 40D je dosta tezak aparat (850g)

Ima li ko iskustva i preporuku?

Canon EOS 550D je 18 Mp i time ima manje piksele od 40D. Obzirom da je tebi losiji flattener, bolji ti je 550D pa onda croppaj na rezoluciju moje kamere (3008x3008px). Koji god fotic da uzmes, obavezno kupi i dummy bateriju sa kabelom i slozi regulator napona sa 12 na 8V (LM338 ili LM350).

Slazem se sa stipom, takodjer ako kameru ne podrzava BackyardEOS onda ti vjerovatno nece raditi ni sa jednim drugim softverom za snimanje, sto je veliki minus

Ili za malo više uzmeš 2000d relativno novi ali puno bolji od ovih ostalih...

obavezno kupi i dummy bateriju sa kabelom i slozi regulator napona sa 12 na 8V (LM338 ili LM350).

Sta god da uradis, nemoj sa linearnim regulatorima (LMxxx ili 78xx) koji visak napona konvertuju u toplotu. Najbolje da i za ovo koristis DC-DC step-down konverter, preporucujem Mini-360. Jeftin je (kupio sam 5 komada za 5 EUR u Novom Sadu, na aliexpress je bilo 5 komada za 1 EUR), velicine je novcica od jednog centa i moze da isporucuje 1.8A kontinuirano sa 95% efikasnosti, 2.5A peak, 3A surge protection. Linearni regluatori su veoma neefikasni (ako svoj rig napajas preko napajanja iz 220V mreze onda to i nije problem, ja svoj napajam tako od kuce ali sa 12V baterije kada idem na udaljene lokacije i svaki amper je bitan). I opet ako imas linearni regulator u kucistu kamere (u dummy bateriji) bespotrebno ce podizati temperaturu u blizini senzora.
