The Second Battle of Komárom, sometimes known as the Battle of Ács, took place at 2 July 1849, between the Hungarian army led by General Artúr Görgei and the imperial army of Austria led by Field Marshal Julius von Haynau, which had an 12 000 strong Russian contingent led by Lieutenant General Fyodor Sergeyevich Panyutyin. The imperial army outnumbered the Hungarian troops by 2 to 1, was superior regarding the multitude of infantry and light as well as heavy cavalry unit types, the quality of the weapons. Except the problems of military kind, problems of other kind influenced negatively the Hungarian army. Short before the battle, the conflict between the Hungarian commander, Görgei, the political leadership of Hungary, Lajos Kossuth and the Szemere-Government, escalated abruptly; the government lead by Kossuth, decided to retreat the Hungarian troops from the defensible Komárom to Southern Hungary, leaving half of the country in the hands of the enemy, without consulting the war minister Görgei, the only person with the right to take a military decision.

Görgei considered this illegal decision as wrong, but he accepted to execute it, in order to avoid the confrontation with the political leadership in such a critical military situation, fixing the date of the depart towards southern Hungary to 3 July. But despite of this, on 31 June Kossuth laid off Görgei from the high command of the Hungarian army, because he had read two of the latters letters in the wrong order. All these caused uncertainty and conflicts among the Hungarian officers and soldiers before this important enemy attack. Kossuth sent Lieutenant General Lázár Mészáros to Komárom, to take the leadership from Görgei, send him to Pest, but when Mészáros approached on 2 July, on a steam boat, to Komárom, he heard the gunshots of the battle, returned to Pest. The Austrian Supreme Commander Field Marshal Julius Jacob von Haynau's plan was to force the Hungarian troops to retreat in the fortress of Komárom, to lay, with a part of his army, a siege against it from the south, opening in this way the road towards Buda and Pest.

After accomplishing this goal the bulk of Haynau's troops had to advance towards East, occupy the Hungarian capitals, before his allies, the Russian main troops led by Ivan Paskevich, arrived there. The battle started on the early morning of 2 July with the attack of the I corps led by General Franz Schlik of the imperial troops from the direction of Ács, chasing away the Hungarians from the Ács forest pushing them into the fortifications lying South from Komárom, capturing the Monostor-trenches, thus entering in the fortifications, menacing to occupy the whole southern fortification and trench system of the fortress, putting in danger the Hungarian troops from there, to be encircled. Artúr Görgei was not expecting a major enemy attack in that day, foreseeing that he will be dismissed from the military leadership, knowing the animosity of the political class against him, in that night and early morning, right when the enemy attack started, he was writing a letter in which he explained the causes of his military decisions, accusing Kossuth for the military and political problems.

He stopped the writing when he heard the sound of the gunshots of the battle, rushed to the battlefield. He arrived on the battlefield, faced the disastrous situation, in which the Hungarian VIII corps was fleeing from the battlefield, letting the Western external trenches of the fortress and some of the fortifications in the hands of the Austrians; the Hungarian main commander, after trying in vain to convince them to fight the advancing Austrians, stopped the rout of the Hungarian soldiers of the VIII corps by commanding grapeshots and volley fire against them, managing with this extreme method to stop them ordering them to regroup, with the support of the VII and II corps, to chase away Schlik's troops from the fortifications, as well as from the Ács forest. The Hungarian counter attack, supported from South by the Hungarian cavalry of the VII corps, led by General Ernő Poeltenberg, put in danger the Austrian left flank commanded by General Franz Schlik to be cut from the rest of the imperial army, but the latter was saved by the involvement in the fights of the Russian division led by Lieutenant General Fyodor Panyutyin and the Austrian Simbschen-brigade of the I. corps, which forced Poeltenberg to retreat, in order to escape the encirclement, thus stopping the Hungarian advancement.

During these fights on the imperial troops left flank, on the right flank, the Austrian brigade of the IV corps, led by General Lajos Benedek occupied Ószőny, which opened the way of the imperials towards Buda and Pest. General György Klapka, the commander of the Hungarian III corps, ordered several counter attacks to reoccupy this crucial locality, but despite some initial successes, his troops were forced to retreat. During these events Haynau was unaware of the situation on the battlefield, thought that his troops had won the battle, ordering his center to retreat from the battlefield, thus putting his army in danger to be destroyed by a Hungarian attack, by cutting his lines in two. Görgei noticed the opportunity, tried to concentrate his cavalry in the middle, massing important artillery units there. Luckily for Haynau, his brigade commanders, as well as Panyutyin, understood the danger and intervened with their troops, closing the gap from their forefront. Görgei unde

The camera has Wi-Fi with NFC, PC sync port and shadow control, a'silent mode' which uses the electronic shutter only. Video features added to the DMC-GH4 include Focus peaking, zebra overlay, luminance level adjustment, cinema gamma presets. Along with the GH4, Panasonic released the YAGH interface unit, a camera-attached device to increase input and output options for the GH4; the YAGH connects to the GH4 via attachment screw on the bottom of the camera, as well as a sliding mechanism which plugs into the camera's HDMI port on the side. The interface contains two 3-pin XLR Connector inputs, which are controlled by a pair of preamplifiers inside the unit, offering phantom power, more control over input gain levels and microphone choice, input metering via LED meters on the interface; the YAGH provides a timecode input for multi-device synchronization. For outputs, the YAGH offers four BNC connector terminals for Serial Digital Interface use with outboard recorders and monitors. In addition, a full-size HDMI port is present.

These video outputs differ from the camera's native recording in that they offer a 10-bit 4:2:2 signal rather than the camera's internal 8-bit 4:2:0. The YAGH interface is not powered by the camera, instead relying on 12-volt DC power provided by a separate battery or power supply using a four-pin XLR type connector.
